We investigated the effects of sequential and prolonged exposure to high and low wall shear stress on arterial remodeling using a rabbit arteriovenous fistula (AVF) model. Blood flow was increased by approximately 17-fold to 20-fold when the AVF was open, and returned to normal when the AVF was occluded. Repeated opening and closing of the AVF resulted in sequential exposure of the artery to hi...
BACKGROUND The FAVOURED study is an international multicentre, double-blind, placebo-controlled trial which commenced recruitment in 2008 and examines whether omega-3 polyunsaturated fatty acids (omega-3 PUFAs) either alone or in combination with aspirin will effectively reduce primary access failure of de novo arteriovenous fistulae (AVF) in patients with stage 4 and 5 chronic kidney disease. ...
The creation of an arteriovenous fistula (AVF) is frequently used to achieve easier access for haemodialysis in patients with chronic renal insufficiency. The most frequent late complication of AVFs is aneurysm formation, which carries the risk of spontaneous rupture. This study reports on 18 patients with giant aneurysms that developed on antebrachial AVFs who were operated on over a period of...
A pulse wave propagation model to support decision-making in vascular access planning in the clinic.
The preferred vascular access for hemodialysis is an autologous arteriovenous fistula (AVF) in the arm: a surgically created connection between an artery and vein. The surgeon selects the AVF location based on experience and preoperative diagnostics. However, 20-50% of all lower arm AVFs are hampered by a too low access flow, whereas complications associated with too high flows are observed in ...
Retrospective Study of Autologous Arteriovenous Fistula Creation as Vascular Access for Hemodialysis
IntroductionAn autologous arteriovenous fistula (AVF) creation is a common vascular procedure forhemodialysis (HD) patients. This surgical aim to design conduct thatwithstands hemodialysis for durable period. However, the functional outcome of this procedurevaries and depends on patients’ various predictors. .MethodsA retrospective observational study was carried out evaluate AVFcreation at car...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2014206870 DESCRIPTION A 67-year-old man presented with non-functioning left brachiocephalic arteriovenous fistula (AVF). The patient was referred for left internal jugular vein (IJV) dialysis catheter placement while awaiting right AVF creation. Ultrasound-guided le...
Refractory chronic colitis presents a medical and surgical challenge, and underlying etiologies are diverse with potential for misclassification as inflammatory bowel disease. We present an unusual case of chronic proctosigmoiditis with rare vascular etiology. A 48-year-old Caucasian male presented with severe diarrhea, weight loss, and abdominal pain. Computed tomography (CT) suggested proctos...
