28,084 | Post-transplant erythrocytosis: a review of 47 renal transplant recipients. | Post-transplant erythrocytosis (PTE) is a well known phenomenon occurring in 5-17% of renal transplant recipients (RTR). In this retrospective study, we studied 47 RTR which included 39 males and eight females. They were divided into two groups according to the presence or absence of PTE, which was defined as a hematoc... |
28,085 | Insertion of short introducer sheaths into a polyurethane vascular access graft for immediate hemodialysis access. | While native AV fistulae are considered the 'gold standard' for hemodialysis patients in need of long-term access, synthetic grafts are the best option for patients who are not candidates for an AV fistula. While AV fistulae should be allowed to mature for 3 - 4 months prior to cannulation, PTFE grafts may be cannulate... |
28,086 | A porcine model of intimal-medial hyperplasia in polytetrafluoroethylene arteriovenous grafts. | Vascular access polytetrafluoroethylene (PTFE) graft failure is a major cause of morbidity in the hemodialysis population. The most common cause of graft failure is thrombosis secondary to stenosis at the venous outflow tract. Venous outflow stenosis is characterized by intimal-medial hyperplasia. We have developed a p... |
28,087 | Internal jugular vein thrombosis after positioning CVC in dialysis patients: The most common ultrasound patterns. | Frequently patients are started on hemodialysis after the placement of a central venous catheter (temporary or tunneled) in the internal jugular vein (IJV). Currenty this procedure is facilitated by ultrasound probes that improve the rate of success of catheter placement in vessels and diminishes the possible complicat... |
28,088 | Antibiotic lock technique for prevention of cuffed tunnel catheter associated bacteremia. | Central venous cuffed tunnel catheters are commonly used for short term or long term hemodialysis access. However, catheter-associated bacteremia is a common complication. It has been suggested that the addition of antibiotics to the catheter during the interdialytic interval results in a decrease in bacterial coloniza... |
28,089 | Surgery versus interventional radiology in the management of thrombosed vascular access for hemodialysis. | Thrombosis is the most frequent complication occurring in vascular access (VA). The two widely used treatment strategies for thrombosed VA are surgical and endovascular. Which is the best and whether different approaches should be used on proximal versus distal VA, is still debated. This is a retrospective study. Over ... |
28,090 | Central venous catheter and the hemodialysis patient: a difficult symbiosis. | In the last ten years, tunneled central venous catheters (pCVCs) have been increasingly utilized in chronic hemodialysis patients, sometimes in the place of fistulas. They have gained popularity for their unquestioned advantages, such as the possibility for immediate use. However, several problems have emerged followin... |
28,091 | Improved measurement of vascular access pressure. | Vascular access stenosis and thrombosis is one of the key problems for hemodialysis patients. Prospective monitoring of static venous dialysis pressures can be applied to detect outflow stenoses in a vascular access. However, the location of stenoses within the access may influence the diagnostic value of venous pressu... |
28,092 | Measuring central venous structures in humans: implications for central-vein catheter dimensions. | The tip of a central vein catheter for hemodialysis should be located in the upper right atrium for the best performance. Hemodialysis catheters do have internal diameter unadjusted to the catheter length; however, the longer the catheter the slower the flow at the same pressure difference. On the other hand, the cathe... |
28,093 | Restoration of acutely thrombosed arterio-venous fistulae by rTPA and percutaneous angioplasty. | Acute thrombosis in native arterio-venous fistulae (AVF) results in considerable patient morbidity.
