The problem first showed up when a big blood clot blocked veins in her brain, and a clot also went to her lungs. She took blood thinners and steroid pills. Later she took a medicine that calms the immune system to help her use fewer steroids. Tests showed no inherited blood-clotting problem. She had several flare-ups of the kidney problem. Steroid pills controlled them until 2017. After that she had no relapses. Her doctors stopped the blood thinner and the immune-calming medicine. One year later she had sudden, very bad belly pain all over. She threw up after eating. Both legs were swollen. Tests showed the kidney problem was back. A special X-ray picture (CT scan) showed a new clot in the main artery that feeds the small intestine. It was like a plug in a pipe that stops water. Blood could not reach the intestines. In surgery, most of her small intestine was dead. Taking out that much bowel would not allow life. She died 48 hours later.",

After being directly admitted into ICU, she lost consciousness and lapsed into a coma. Tests revealed that she had hyperparathyroidism, a rare disease in which a defective parathyroid gland allows dangerously high calcium levels (hypercalcaemia). Being too weak for an operation to remove her parathyroid, she was placed on an artificial lung and heart machine. After five days and requiring dialysis several times a day, Stella showed signs of improvement. Unfortunately, complications soon developed. A restricted blood-flow to her right leg caused infection and an above-the-knee amputation was required. Soon after the removal of the leg, and with signs of infection having disappeared, Stella's parathyroid gland was then safely removed, ensuring her survival. Stella woke from the coma one month after she was admitted.",

Kidney biopsy was deferred because there was no kidney failure, gross hematuria, hypertension, or extra\u2011renal signs suggestive of secondary NS at presentation. She was treated with an oral vitamin K antagonist and oral corticosteroids with good evolution. Subsequently, she had multiple steroid\u2011dependent relapses and was started on mycophenolate mofetil (MMF) as background therapy to spare corticosteroids and ensure normal growth. An exhaustive thrombophilia assessment was negative: homocysteine, fibrinogen, protein C, protein S, antithrombin III, factor V Leiden, JAK\u20112, cryoglobulins, anticardiolipin antibodies, lupus anticoagulant, and anti\u2011\u03b22\u2011glycoprotein I antibodies were all normal. Anticoagulation was stopped after nine years. Several relapses occurred but were controlled with oral corticosteroids. NS remission was documented from 2017; MMF was gradually discontinued in 2019, and she remained asymptomatic without relapse.\n\nOne year later, she presented to the emergency department with acute intense diffuse abdominal pain without irradiation, associated with postprandial vomiting and bilateral lower\u2011limb edema for six hours. Examination showed intense epigastric tenderness with normal vital signs (BP 120/70 mm Hg, HR 83 bpm, SpO2 100% on room air) and no fever or neurological impairment. Urinalysis detected proteinuria. Hemogasanalysis showed metabolic acidosis with respiratory compensation. Labs revealed hypoalbuminemia, hypercholesterolemia, prothrombin time 90%, elevated D\u2011dimer, LDH, and creatine phosphokinase, with inflammatory markers (CRP 37 mg/L) and leukocytosis (26.4 \u00d7 10^3/\u00b5L); renal and liver function were normal. Urgent abdominal ultrasound showed a low\u2011to\u2011moderate intra\u2011abdominal effusion. Contrast\u2011enhanced CT demonstrated acute thrombosis of the superior mesenteric artery with acute mesenteric ischemia. She underwent emergency laparotomy: intraoperative exploration confirmed mesenteric ischemia with extensive necrosis of almost the entire small bowel, rendering resection incompatible with life. She died 48 hours later.\n\nThis case illustrates catastrophic arterial thrombosis in the setting of NS despite a negative thrombophilia work\u2011up. NS is a hypercoagulable state with multifactorial mechanisms, including urinary loss of anticoagulant proteins (e.g., antithrombin III, protein S), increased fibrinogen, hemoconcentration, dyslipidemia, and systemic inflammation. While venous thromboembolism is more common in NS, superior mesenteric artery thrombosis is rare but often fatal, underscoring the need for high clinical suspicion and rapid imaging when severe acute abdominal pain occurs in patients with active or relapsing NS.",
            "selected_wiki_anchor": "Cholesterol embolism occurs when cholesterol is released, usually from an atherosclerotic plaque, and travels as an embolus in the bloodstream to lodge (as an embolism) causing an obstruction in blood vessels further away. Most commonly this causes skin symptoms (usually livedo reticularis), gangrene of the extremities and sometimes kidney failure; problems with other organs may arise, depending on the site at which the cholesterol crystals enter the bloodstream. When the kidneys are involved, the disease is referred to as atheroembolic renal disease. The diagnosis usually involves biopsy (removing a tissue sample) from an affected organ. Cholesterol embolism is treated by removing the cause and giving supportive therapy; statin drugs have been found to improve the prognosis.",

On examination she was alert, oriented, and without focal language, motor, or sensory deficits; a right lateral tongue bite was noted. Laboratory tests and ECG were unremarkable. Given a first epileptic seizure in pregnancy, an urgent cranial MRI was performed. The protocol included 3D T1 pre- and post-contrast (axial, coronal, sagittal), axial FLAIR, axial T2, VEN BOLD and magnetic susceptibility sequences, as well as axial diffusion and ADC mapping. MRI demonstrated multiple venous cortico-medullary vascular structures converging centripetally to a large central draining vein that emptied via the inferior anastomotic vein into the left transverse sinus, forming the classic \u201cMedusa head\u201d sign. On T1 post-contrast, the drainage vein showed increased signal with central hyphocaptation, suggesting partial thrombosis versus slow flow. On T2 and FLAIR, the parenchyma surrounding the drainage vein was hyperintense, without diffusion restriction, compatible with edema. Overall, the findings are diagnostic of a developmental venous anomaly with signs of partial peripheral thrombosis and more proximal slow flow, causing perilesional edema. Management was initiated with clexane 60 mg every 12 hours and levetiracetam 500 mg every 12 hours, with symptomatic improvement and stability after one week. Contextually, DVAs are typically benign venous variants; however, pregnancy-associated hypercoagulability may predispose to thrombosis. Partial thrombosis and impaired outflow in a DVA can lead to venous congestion and edema, manifesting clinically with seizures.",

This disease is further divided into three subgroups, namely neonatal arterial ischemic stroke, neonatal cerebral sinovenous ischemic stroke, and presumed perinatal stroke. Several risk factors contribute to perinatal stroke including birth trauma, placental abruption, infections, and the mother's health. Detection and diagnosis of perinatal stroke are often delayed due to prenatal onset or inadequacy of neonatal signs and symptoms. A child may be asymptomatic in the early stages of life and may develop common signs of perinatal stroke such as seizures, poor coordination, and speech delays as they get older. Diagnostic tests such as magnetic resonance imaging, electroencephalogram, and blood tests are conducted when doctors suspect the patients have developed signs of  a perinatal stroke. The prognosis of this disease is associated with the severity and the development of the symptoms. This disease can be treated by anticoagulant and anticonvulsant drugs, surgical procedures, and therapeutic hypothermia, depending on the condition of the patient.",

The episode began with fever followed by pimple-like lesions on the lips. She had used pod-type vapes for approximately one year, often trying different e-liquid flavors; she had never smoked conventional cigarettes. She reported no medication exposure prior to onset (no antibiotics, analgesics, anticonvulsants, NSAIDs, or antifungals), no drug or food allergies, and unhealthy eating habits.

Intraoral examination showed multiple painful white ulcers with yellowish edges, irregular and variable in size, on the labial and buccal mucosa, lateral and ventral tongue, and floor of mouth. Anti-HSV-1 IgG was non-reactive. Based on isolated oral mucosal involvement, absence of cutaneous lesions, and negative HSV serology, a diagnosis of vaping-related oral erythema multiforme, minor type, was established. Management comprised 0.9% NaCl\u2013moistened gauze compresses to the lips three times daily; a dexamethasone mouthrinse (1 mg in 10 mL hyaluronic acid) three times daily with a 30-minute post-rinse fasting period; 2% miconazole cream applied to the wound at the right labial commissure twice daily; and vaseline album (petrolatum) for dry lips.

He had previously received azithromycin and supplemental oxygen without improvement. On exam, there was mild subcostal retraction, decreased vesicular breath sounds over the left hemithorax, and scant wheezes predominating on the right; he required 4 L/min oxygen via binasal cannula. Laboratory studies showed WBC 8.03 \u00d7 10^3/\u03bcL, platelets 209 \u00d7 10^3/\u03bcL, hemoglobin 13.2 g/dL, and CRP 36.6 mg/L. Imaging included a chest study and head and neck tomography; chest tomography visualized several pulmonary cysts. Forty-eight hours after admission, he developed worsening stridor and respiratory distress, prompting emergent OR transfer for tracheostomy, microlaryngoscopy, and excision of papillomatous lesions. Intraoperative findings demonstrated extensive papillomatous disease with appendicular tumor-like lesions and ventricular bands involving the epiglottis, glottic surface, vocal cords, subglottis, and trachea to ring 5. Histopathology showed koilocytotic atypia consistent with HPV and mild focal dysplasia. Postoperatively, he was managed in the PICU with respiratory monitoring and was weaned off oxygen within 48 hours. He received a single intravenous dose of bevacizumab 400 mg and showed prompt clinical improvement. He completed a seven-day hospitalization with normalization of oxygen saturation and progressive oxygen weaning, then was transferred for ongoing care. He also received respiratory therapy. On telemonitoring at eight months, there was no evidence of recurrence or intercurrent events. Clinical context: RRP is typically HPV-related (often low-risk types) and can cause multifocal papillomas leading to airway stenosis; anti-VEGF therapy such as bevacizumab is used off-label to reduce angiogenesis and disease recurrence, and in this case was associated with a favorable short- to mid-term outcome.",

On admission (August 8, 2016): BMI 24.5 kg/m2, T 39.0\u00b0C, tachypnea 35 breaths/min, severe hypoxemia (SaO2 86%). Auscultation revealed good bilateral air entry with scattered diffuse crackles and rhonchi. Chest CT demonstrated multiple bilateral ground-glass opacities. Initial labs showed a normal WBC count with elevated neutrophils and increased inflammatory markers (CRP, ESR) and elevated (1\u21923)-\u03b2-D-glucan. Serology was positive for RSV antibodies on hospital day 4; other pathogen testing was negative. He had laboratory evidence of immunosuppression with decreased total IgG and reduced CD4 and CD8 T-lymphocyte counts, consistent with chronic exposure to corticosteroids and immunosuppressants.\n\nManagement: Immediate respiratory monitoring and supplemental oxygen were initiated. Empiric anti-infective therapy included antibiotics (moxifloxacin for 4 days, then cefminoxine for 8 days) and antifungal therapy (voriconazole for 10 days). The glucocorticoid and immunosuppressant doses were largely unchanged. After 10 days, clinical status and oxygenation worsened with radiographic progression. He was transferred to the Emergency ICU for noninvasive mechanical ventilation, broad-spectrum antibiotics (i.v. meropenem, oral moxifloxacin, cotrimoxazole), antifungal therapy (micafungin), systemic corticosteroids (methylprednisolone 40 mg bid i.v.), and supportive care. Ganciclovir was added for possible viral coinfection (e.g., CMV). Five days later, chest x-ray showed further aggravation. Despite escalation to invasive ventilator-assisted ventilation, higher-dose methylprednisolone (80 mg bid), additional antibacterials (cefoperazone-sulbactam, tigecycline, cotrimoxazole), and continued micafungin, he developed rapid progression culminating in respiratory failure and death two days later.\n\nInterpretation: The presentation is consistent with severe viral pneumonia due to RSV in an immunocompromised host, with imaging showing multifocal ground-glass opacities and laboratory evidence of systemic inflammation. Elevated (1\u21923)-\u03b2-D-glucan prompted antifungal coverage, while broad-spectrum antibacterial and antiviral regimens addressed possible coinfections.

The clinical course began with lower back pain attributed to bilateral renal lithiasis; after spontaneous passage of a stone she had 3 days of haematuria and was given tranexamic acid q12h. Three weeks later she developed progressive pain and induration of the left distal thigh. Following intramuscular diclofenac for persistent pain, she developed ecchymosis and ongoing bleeding in the gluteal area despite compression. An outside \u201cparticular Doppler ultrasound\u201d reportedly showed deep venous thrombosis (left lower limb), and she was started on enoxaparin 30 mg SC q24h plus morphine and hospitalized. The next day she developed epigastralgia, blurred vision, HR 117 bpm, BP 113/85 mmHg, and SpO2 93%; enoxaparin was discontinued. Hemoglobin fell from 10.4 g/dL (day prior to admission) to 6.4 g/dL, prompting 2 units of packed red cells. With a working diagnosis of vasculitis, methylprednisolone was started and she was referred for further evaluation.\n\nOn admission she had severe pallor, extensive ecchymosis of the left thigh and lateral knee, and a right thigh haematoma. Hemogram: Hb 9.8 g/dL, normocytic, normochromic. Chemistry notable for glucose 160 mg/dL; AST 52 U/L, ALT 86 U/L. Coagulation profile showed isolated prolongation of the activated partial thromboplastin time (aPTT) to 91.2 s; the remainder of hemogram, biochemistry, electrolytes, liver profile, and coagulation parameters were within reference limits. Soft-tissue ultrasound of the right gluteal region revealed a subcutaneous collection (TCSC) with oedema extending to the upper third of the thigh. Repeat Doppler ultrasound of the left lower limb showed normal flow without thrombosis in the common femoral, superficial, or deep venous systems. Blood and urine cultures were negative. ANA, C3, C4, and ferritin were within reference ranges.\n\nGiven suspected acquired haemophilia, a mixing test demonstrated partial correction of the aPTT. Factor VIII activity was <1.0 U/dL, and a factor VIII inhibitor was detected at 8.64 Bethesda units/mL, confirming acquired haemophilia A, likely postpartum in onset. Therapy included prednisone 50 mg PO at breakfast plus 10 mg at lunch, cyclophosphamide 50 mg (2 tablets) PO q24h, and FEIBA for haemostasis. After 5 days, FEIBA was discontinued due to chest tightness, dyspnoea, and nausea (suspected adverse drug reaction) and replaced with activated recombinant factor VII (rFVIIa; NovoSeven). Clinical evolution was favourable, with decreasing ecchymoses and no new symptoms, and she was discharged.\n\nContext: Postpartum acquired haemophilia A is mediated by autoantibodies to factor VIII and typically presents with isolated aPTT prolongation, low FVIII activity, and an inhibitor measured in Bethesda units. Partial correction on mixing supports an inhibitor pattern. First-line immunosuppression (e.g., prednisone with or without cyclophosphamide) and bypassing agents (FEIBA or rFVIIa) are standard to control bleeding while eradicating the inhibitor.",

On ED arrival he was afebrile, with non-evaluable BP, depressed consciousness, generalized hypertonia, and bilateral pretibial oedema. He was intubated and loaded with phenobarbital 10 mg/kg. In the ICU, BP was 134/94 mmHg (p95 for age 108/66; p95+12 120/78), consistent with hypertensive emergency. Initial labs: urinalysis with haematuria (>100 RBC/hpf), proteinuria 3+, leucocyturia 10\u201325/hpf; creatinine 0.3 mg/dL; anaemia Hct 21%, Hb 7 g/dL with normocytic, normochromic indices; leukocytosis 23,900/mm3; thrombocytosis 756,000/mm3; no elevation of acute-phase reactants; hypocomplementemia with C3 25 mg/dL (VN 80\u2013150) and normal C4. Throat rapid antigen for group A Streptococcus was positive and ASO positive. Non-contrast head CT was unremarkable. Renal ultrasound showed bilateral nephromegaly with increased cortical echogenicity and decreased corticomedullary differentiation. The working diagnosis was nephritic syndrome due to complicated GNAPE with hypertensive emergency and status epilepticus. He required mechanical ventilation and phenobarbital; EEG the next day was normal; CSF was normal. Cefotaxime was started for Streptococcus pyogenes eradication and furosemide for diuresis. By day 2 he developed AKI (creatinine 0.99 mg/dL), hypertension, and 24-hour proteinuria 36.6 mg/m2/h without oliguria. Antihypertensive therapy included amlodipine and IV labetalol with initial control. After extubation at 48 hours, he deteriorated neurologically within 24 hours (GCS 8) with BP > p95+12 despite labetalol infusion up to 3 mg/kg/h, amlodipine 10 mg/day, and furosemide, necessitating reintubation and sodium nitroprusside infusion up to 3 mcg/kg/min with a planned gradual BP reduction of 25% per day to mitigate secondary neurologic injury. Given acute neurologic deficits with severe HTN in GN, PRES was suspected and confirmed by brain MRI on day 5 showing increased subcortical T2/FLAIR signal in bilateral symmetric occipital regions without diffusion restriction, consistent with vasogenic edema. Ophthalmologic exam was normal; repeat EEG showed occasional generalized voltage depression. Enalapril was added. Over 10 days, BP normalized with slow pharmacologic weaning; follow-up MRI on day 12 showed radiologic regression, and he was successfully extubated after 5 days. During the ICU course, Hb fell to 5 g/dL with normocytic, normochromic indices and no thrombocytopenia; hemolytic anemia was diagnosed given a positive direct Coombs test and hemoglobinuria. He required two packed RBC transfusions. Methylprednisolone 1 mg/kg/day was given for 72 hours. Stool culture and urinary antigen for Streptococcus pneumoniae were negative. Serologies for EBV and Parvovirus B19, ENA profile, ANCA, anti-dsDNA, anti-\u03b22 glycoprotein I, anticardiolipin, and lupus anticoagulant were all negative; all cultures (blood, urine, endotracheal aspirate, pharyngeal) were negative. ANA was positive at 1:160. Clinical status improved with BP control, rising complement levels, and resolution of proteinuria and haematuria; the direct Coombs remained positive on hospital day 9. He was discharged on day 31 normotensive, non-anaemic, with preserved renal function, no proteinuria or haematuria, normalized C3, and asymptomatic neurologically. Discharge medications: prednisone, amlodipine, enalapril, and folic acid. He remained asymptomatic with no recurrence at 6 months. Overall, the case represents GNAPE with hypocomplementemia (low C3) and elevated ASO complicated by hypertensive emergency causing encephalopathy and secondary PRES, plus autoimmune hemolytic anemia with Hb nadir 5 g/dL, successfully managed with antihypertensives, neuroprotective measures, and corticosteroids, with full clinical and radiologic recovery.",

His history included an inferior STEMI in 2009 with severe 3-vessel disease (proximal LAD CTO, 90% mid/distal LCx stenoses, 95% mid RCA stenosis) treated with CABG (LIMA\u2013LAD; sequential SVG to OM1, OM2, and PL). Current angiography via 6 Fr left radial access showed patent LIMA\u2013LAD and SVG\u2013OM1/OM2, but complete occlusion of the sequential SVG to PL. The native LM was occluded at the ostium and the native RCA was occluded in the mid segment with bridging collaterals. The strategy was to treat the native RCA CTO. Dual arterial access was obtained with an additional 6 Fr right femoral sheath. The right and left coronaries were engaged with 6 Fr AL 0.75 (Launcher; Medtronic) and 6 Fr EBU 3.5 (Launcher; Medtronic) guide catheters, respectively. An antegrade approach from the left radial artery failed: neither a Fielder XTR nor a Gaia 3 with a Finecross microcatheter could enter the distal true lumen. A parallel wire technique with a Crusade microcatheter and two Gaia 3 wires also failed. The team then switched to a retrograde approach via septal channels from the LAD through the occluded left coronary system. A Gaia 3 crossed the occluded LM and LAD to reach the distal LAD true lumen. A Sion wire was exchanged via a Finecross into the distal LAD, followed by dilation of the LM and proximal LAD with a 2.0 \u00d7 15 mm balloon. Septal surfing technique (SST) was then used to identify a viable septal channel. A Sion wire, supported by a 150-cm Finecross, was advanced retrogradely through a distal septal branch into the distal RCA. A Gaia 3 traversed the RCA CTO retrogradely into the proximal RCA true lumen and was advanced into a Guidezilla guide extension catheter positioned in the antegrade guide. The Finecross was delivered to the antegrade guide and an RG3 wire was externalized. The CTO segment was predilated with a 2.0 \u00d7 15 mm balloon and stented with two overlapping DES (2.5 \u00d7 38 mm and 3.0 \u00d7 38 mm), achieving an excellent angiographic result with TIMI 3 flow in all distal branches.

            "selected_wiki_anchor": "Background\nCoronary artery disease is a condition in which the blood vessels to the heart become clogged.\nIt often leads to heart attacks and is one of the leading causes of death in the United States. Beginning in the mid-1960s, the leading treatment consisted of invasive bypass surgery, in which a healthy blood vessel from another part of the body is grafted onto the coronary artery, forming a detour around the afflicted region. Due to the high cost and risk of this procedure, an alternative was in high demand. In 1977, Andreas Gruentzig performed the first successful percutaneous coronary angioplasty. In this procedure, a catheter attached to a small balloon is inserted into the afflicted artery. The balloon is subsequently expanded, compressing the accumulated plaque to allow increased blood flow. This was a substantial improvement over bypass surgery in terms of invasiveness, but unfortunately restenosis, a recurrence of arterial clogging, occurred in nearly 50% of patients after the balloon was removed.",

Primary angioplasty of the right coronary artery was performed with successful placement of a drug-eluting stent. The hemodynamicist noted possible aortitis given arch involvement and vessel friability during balloon advancement and recommended an inflammatory/etiologic evaluation prior to definitive management of the left main lesion.\n\nLaboratory testing showed mild anemia (hemoglobin 11.6 g/dL), mild leukocytosis (13,800/mm3), elevated ESR 42 mm/h, CRP 4.9 mg/L (normal <1), and elevated high-sensitivity troponin. Autoimmunity panel: normal complement C3/C4, negative ANA, anti-DNA, and ENA profile; non-reactive VDRL.

He had never undergone surgery or prosthetic device implantation and had no history of immunosuppressive therapies.\n\nEight days after a routine visit, he developed dyspnea and fever >38\u2103. On arrival: BP 192/82 mmHg, HR 118/min, orthopnea, SpO2 80%. Exam: Levine 3/6 systolic murmur; no Osler nodes, Janeway lesions, or conjunctival petechiae. Labs: WBC 20,800/\u03bcL, CRP 6.06 mg/dL, CK\u2011MB 6.0 IU/L, troponin T negative. CXR showed pulmonary congestion with cardiomegaly (CTR 55%). ECG had ST elevation in V1\u2013V4, but emergent echocardiography showed no systolic dysfunction. He was diagnosed with acute heart failure due to valvular disease and treated with non\u2011invasive positive pressure ventilation and nitrates.\n\nTransthoracic echocardiography demonstrated severe aortic regurgitation and severe mitral regurgitation with a mobile mitral vegetation. Transesophageal echocardiography identified a 16.5\u00d76\u2011mm mobile vegetation on the anterior leaflet of the mitral valve and an 11.2\u00d75\u2011mm nonmobile vegetation on the noncoronary cusp of the aortic valve, raising strong suspicion for native valve endocarditis (NVE). Head CT and MRI showed no cerebral infarction or hemorrhage.\n\nRetrospective review revealed subtle abnormalities starting four months pre\u2011admission: mildly elevated WBC, albumin decreased to 3.0 g/dL the following month, and gradual hemoglobin decline over two months, with a 4\u2011kg weight loss. EGD and whole\u2011body CT were unrevealing. He partially regained weight and labs nearly normalized except for a CRP of 0.54 mg/dL. At the last pre\u2011admission visit (8 days prior), WBC was 9,300/\u03bcL, Hb 13.1 g/dL, Alb 3.0 g/dL, CRP 4.18 mg/dL, and diastolic BP had fallen; he remained afebrile and asymptomatic aside from weight loss.\n\nEmpiric antibiotics were initiated with ampicillin\u2013sulbactam 12 g/day plus gentamicin 120 mg/day. Three admission blood culture sets all grew Staphylococcus warneri, a coagulase\u2011negative staphylococcus (CoNS) and resident skin flora (MICs: ABPC/S \u22648 \u03bcg/mL; GM \u22641 \u03bcg/mL; CEZ \u22642 \u03bcg/mL), confirming S. warneri IE. Per Japanese Circulation Society guidance, emergency surgery is generally recommended for NYHA III\u2013IV heart failure or urgent surgery for NVE with mobile vegetation >10 mm and severe valve dysfunction. Because heart failure improved rapidly and appropriate antibiotics were started (reducing embolic risk), and given poorly controlled type 1 diabetes increasing operative risk, elective surgery was planned after stabilization of infection and glycemia. Antibiotics were narrowed to cefazolin 6 g/day; dental evaluation showed no periodontitis.\n\nAfter four weeks of antibiotics, surgery revealed a bicuspid aortic valve with intact aortic and mitral annuli and no abscess. Large vegetations were exenterated, and both valves were replaced with mechanical prostheses. The postoperative course was uneventful; he was discharged on postoperative day 22 without apparent embolism and has remained recurrence\u2011free for over two years.

After multidisciplinary review, robot-assisted TPC was performed under approvals from the Evaluating Committee for Highly Difficult New Medical Technologies (H-0051) and the Kyoto University IRB.\n\nUnder general anesthesia in lithotomy with arms tucked, a 5-cm vertical umbilical incision was made and a wound protector placed. After pneumoperitoneum, 4 robotic and 2 assistant trocars were inserted. Instruments included a camera, monopolar curved shears (right hand), bipolar fenestrated forceps (left hand), and Cadiere/double-fenestrated forceps (reserve arm). Two table positions (Trendelenburg and flat) were used with specific docking tilts; arm cart angles were unchanged.

This corresponds to a D3 lymph node dissection of the left colon/rectum.\n\nStep 3: After undocking and repositioning the patient flat, CVL along the superior mesenteric artery (SMA) was performed, ligating the ileocolic, right colic, and middle colic vessels; the inferior mesenteric vein (IMV) was ligated at its root (exposed in Step 2).\n\nTransanal and small laparotomy procedures: After transection of the terminal ileum, a transanal specimen extraction was performed with complete rectal mucosectomy from just below the dentate line due to multiple adenomas in the anal canal. An ileal pouch was constructed via the small umbilical incision, its reach to the anal canal confirmed, and a transanal hand-sewn IPAA was completed.

He initially self-managed with analgesics and did not seek care. He reported inability to fully extend the right middle finger. Examination demonstrated edema and a boutonniere posture (PIP flexion, DIP hyperextension). Active PIP ROM was 45\u2013110 degrees, with passive PIP ROM within normal limits. Radiographs of the right hand (AP/lateral) revealed no osseous pathology, supporting a soft-tissue etiology consistent with a central slip injury. \n\nSurgical technique: Central slip defect reconstruction was performed using the partial ulnar slip of the flexor digitorum superficialis (FDS) tendon. Under anesthesia and tourniquet control in the supine position, a midlateral incision was made on the ulnar aspect of the middle phalanx centered at the PIP joint with dorsal oblique extension, and a transverse incision was made over the MCP flexion crease proximal to the A1 pulley. The ulnar digital neurovascular bundle was identified and protected. Full-thickness dorsal flaps were elevated to expose the central slip and extensor mechanism to the PIPJ. Scar and pseudotendinous tissue were excised. The central slip was not amenable to primary repair; therefore, the ulnar slip of the FDS was selected for reconstruction. The ulnar neurovascular bundle was mobilized to visualize the periosteal insertion of the A3 pulley. The extensor tendon was mobilized and tenolyzed; the dorsal PIP capsule was incised with removal of interposed tissue. The A3 pulley periosteal insertion and the volar capsule of the PIP joint were incised longitudinally. A 2\u20130 non-absorbable monofilament suture was placed around the ulnar FDS slip at the PIP level. Through the proximal incision, the flexor sheath and A1 pulley were incised longitudinally to expose the FDS; the ulnar slip was isolated and transected, preserving the radial slip. The previously placed 2\u20130 suture facilitated delivery of the distally based ulnar FDS slip distally. A 2.8\u2011mm dorsal-to-volar bone tunnel was drilled at the base of the middle phalanx; an elevator protected the FDP, volar plate, and volar structures. With the PIP reduced in full extension, the FDS slip was passed through the tunnel and routed through the intact proximal segment of the central slip/extensor tendon. A tendon weaver completed a Pulvertaft weave under appropriate tension with the PIP in full extension and reduction, secured with 3\u20130 non-absorbable suture. The capsule and central slip reconstruction margins were approximated; adhesions were released and lateral bands mobilized. Tenodesis effect, posture, stability, and motion were assessed. Wounds were irrigated, the tourniquet deflated, hemostasis obtained, and capillary refill confirmed. Skin was closed with horizontal mattress sutures. A sterile dressing and a well-padded PIP extension splint were applied to allow early DIP and MCP motion.\n\nPostoperative course: First wound check at postoperative day 4; the patient received meloxicam 7.5 mg PO BID and doxycycline 100 mg PO BID for 3 days. A second wound visit occurred 3 days later. At 2 weeks, the back slab and external sutures were removed, and active and passive PIP ROM exercises were initiated. By 3 weeks, the wound had healed and PIP ROM was 0\u201390 degrees. At 1 month, PIP ROM improved to 0\u2013100 degrees, with continued functional gains. After 7 weeks of rehabilitation, he returned to work with PIP ROM 0\u2013110 degrees. Overall function improved substantially, with the DASH score decreasing from 50 to 4.2.\n\nInterpretation: Clinical and radiographic findings were concordant with a chronic central slip injury producing boutonniere deformity (PIP flexion, DIP hyperextension due to dorsal apparatus disruption and volar migration of lateral bands). Reconstruction using an ulnar FDS slip via bone tunnel and Pulvertaft weave restored PIP extension and yielded progressive ROM gains and marked functional recovery.",

Low blood pressure and a fast heart rate after the event may indicate blood loss or dehydration, while low blood oxygen levels may be seen following the event in those with pulmonary embolism. More specific tests such as implantable loop recorders, tilt table testing or carotid sinus massage may be useful in uncertain cases. Computed tomography (CT) is generally not required unless specific concerns are present. Other causes of similar symptoms that should be considered include seizure, stroke, concussion, low blood oxygen, low blood sugar, drug intoxication and some psychiatric disorders among others. Treatment depends on the underlying cause. Those who are considered at high risk following investigation may be admitted to hospital for further monitoring of the heart.",
