29,783 | Hemodialysis access graft failure: time to revisit an unmet clinical need? | Hemodialysis (HD) access complications constitute a major cause of morbidity in HD patients. The failure of HD access grafts is predominantly due to progressive intimal hyperplasia (IH) at the venous anastomosis, resulting in a graft flow decline, which ultimately gives rise to graft thrombosis. To date, all tested pha... |
29,784 | Simultaneous rupture of the liver and spleen in a patient on warfarin therapy: report of a case. | Although there are many reports describing spontaneous rupture of either the spleen or the liver, the simultaneous rupture of both organs is a rare event, especially during anticoagulant therapy. We report a case of spontaneous rupture of the spleen and liver in a patient on warfarin therapy for deep venous thrombosis. |
29,785 | Acute mesenteric ischemia: the challenge of gastroenterology. | Intestinal ischemia has been classified into three major categories based on its clinical features, namely, acute mesenteric ischemia (AMI), chronic mesenteric ischemia (intestinal angina), and colonic ischemia (ischemic colitis). Acute mesenteric ischemia is not an isolated clinical entity, but a complex of diseases, ... |
29,786 | In-depth study of tripeptide-based alpha-ketoheterocycles as inhibitors of thrombin. Effective utilization of the S1' subsite and its implications to structure-based drug design. | Thrombin inhibitors are potentially useful in medicine for their anticoagulant and antithrombotic effects. We synthesized and evaluated diverse heterocycle-activated ketones based on the d-Phe-Pro-Arg, and related thrombin active-site recognition motifs, as candidate inhibitors. The peptide-based alpha-ketoheterocycles... |
29,787 | [Changes in D-dimer levels during pregnancy and the postpartum period: results of two studies]. | In outpatients D-dimer (DD) measurement is included in most algorithms to exclude venous thromboembolism (VTE). We have recently performed two studies to evaluate the evolution of DD during pregnancy and the postpartum. During pregnancy, DD increase progressively and are of poor value to exclude VTE after 20 weeks of g... |
29,788 | [Diagnosis of suspected deep venous thrombosis and pulmonary embolism during pregnancy]. | Venous thromboembolic disease (VTE) is a frequent clinical problem during pregnancy and post-partum. Pulmonary embolism (PE) remains the most common cause of mortality during pregnancy and post-partum in western countries. In the majority of cases, DVT may be diagnosed by non-invasive tests such as clinical probability... |
29,789 | [Thrombosis prophylaxis with heparins in intensive care patients]. | Venous thromboembolism is a common complication in critically ill patients, resulting in high morbidity and mortality. Most patients treated in intensive care units (ICU) face a high risk of thromboembolic complications. There is a need for well-defined strategies for prevention of thrombosis in ICU patients. Mechanica... |
29,790 | [Popliteal vein entrapment in patients with unspecific symptoms of venous insufficiency]. | Popliteal vein entrapment must be taken in consideration in patients with symptoms of venous insufficiency. Leg edema, swelling, calf pain, and muscle cramps are all unspecific signs. Most patients thus far have presented with deep vein thrombosis or chronic venous insufficiency. Popliteal entrapment syndrome must be t... |
29,791 | Multimodal percutaneous intervention for critical venous occlusive disease. | Critical deep venous thrombosis and occlusion constitutes a small percentage of patients with venous disease, who exhibit severe symptomatology. This study examined the results of multimodal percutaneous therapy for the treatment of complex critical venous thrombotic and occlusive disease. Twenty-five patients presente... |
29,792 | Clinical features of postoperative cerebral venous infarction. | There is a potential risk of sacrificing the cortical vein during neurosurgical operations, particularly in the interhemispheric or subtemporal approach. An impaired cortical vein might cause cerebral venous circulatory disturbances (CVCDs) resulting in venous infarction. In this article, we have reviewed the managemen... |
29,793 | Influence of warfarin on symptoms of fatigue: findings of a randomized trial. | Some patients develop fatigue while taking warfarin, but causality is uncertain.</AbstractText>To assess whether warfarin use is associated with fatigue.</AbstractText>This investigation was a substudy of a randomized double-blind trial in 13 outpatient thromboembolism clinics. Subjects who had received one month of op... |
29,794 | Impending paradoxical embolism across a patent foramen ovale: case report. | We describe a case of impending paradoxical embolism in a 43-year-old male patient with pulmonary embolism. Transesophageal echocardiography revealed a thromboembolus straddling a patent foramen ovale. The patient underwent emergency removal of the intracardiac clot with closure of the patent foramen ovale. A postopera... |
29,795 | Anticoagulant and antithrombotic activities of a chemically sulfated galactoglucomannan obtained from the lichen Cladonia ibitipocae. | A galactoglucomannan (GGM), isolated from the lichen Cladonia ibitipocae, consisted of a (1-->6)-linked main chain of alpha-mannopyranose units, substituted by alpha- and beta-D-galacto (alpha- and beta-D-Galp)-, beta-D-gluco (beta-D-Glcp)- and alpha-D-mannopyranosyl (alpha-D-Manp) groups, and was sulfated giving a ... |
29,796 | [Study on the risk factors of deep venous thrombosis in acute hospitalized stroke patients]. | To identify the risk factors of deep venous thrombosis (DVT) in hospitalized patients with acute stroke, under a perspective case-control study.</AbstractText>488 cases with stroke, identified by CT or MRI and admitted to the department of neurology and neurosurgery in Beijing Chaoyang Hospital between December 2001 an... |
29,797 | [Routine nursing measures for thrombosis prevention in a university hospital]. | A literature search on the subject of thrombosis prevention showed that there have been changes in preventive nursing measures in the last three decades. Data on preventive measures as actually employed at the different Clinics of the Innsbruck Medical University were gathered with the help of written questionnaires (c... |
29,798 | [Mesenteric vein thrombosis: clinical manifestations, treatment and outcome]. | Mesenteric vein thrombosis (MVT) is uncommon and accounts for 5-10% of all mesenteric ischemic events. In 80% of cases, an etiologic factor is found. The clinical presentation varies and the diagnosis is made based on imaging studies. The treatment involves anticoagulation alone or in combination with surgery.</Abstrac... |
29,799 | Subclavian vein obstruction without thrombosis. | Unilateral arm swelling caused by subclavian vein obstruction without thrombosis is an uncommon form of venous thoracic outlet syndrome (TOS). In 87 patients with venous TOS, only 21 patients had no thrombosis. We describe the diagnosis and treatment of these patients.</AbstractText>Twenty-one patients with arm swellin... |
