OBJECTIVE Central vein occlusion is a common complication related to central vein catheter insertion for haemodialysis which can be unmasked by an ipsilateral fistula creation, leading to a dysfunctional arteriovenous fistula (AVF). We describe an extra-anatomical venous bypass surgical procedure performed to maintain vascular access and reduce the symptoms of swelling of the ipsilateral upper ...

OBJECTIVE The aim of this paper was to evaluate the repair of onlay autogenous bone grafts covered or not covered by an expanded polytetrafluoroethylene (e-PTFE) membrane using immunohistochemistry in rats with induced estrogen deficiency. MATERIAL AND METHODS Eighty female rats were randomly divided into two groups: ovariectomized (OVX) and with a simulation of the surgical procedure (SHAM)....

We investigated tissue responses to endoskeleton stent grafts for saccular abdominal aortic aneurysms (AAAs) in canines. Saccular AAAs were made with Dacron patch in 8 dogs, and were excluded by endoskeleton stent grafts composed of nitinol stent and expanded polytetrafluoroethylene graft. Animals were sacrificed at 2 months (Group 1; n = 3) or 6 months (Group 2; n = 5) after the placement, res...

Penile augmentation surgical procedure includes diverse graft materials such as artificial collagen material as well as dermo-fat graft. Important factors of postoperative satisfaction are natural appearance of genitalia at the flaccid state and minimal resorption of graft volume. Artificial collagen materials and acellular dermal matrix are available for surgical procedure with variable size. ...

INTRODUCTION Our aim was to evaluate the patency and efficacy of expanded Polytetrafluoroethylene (ePTFE) vascular graft in hemodialysis patients. MATERIALS AND METHODS In a prospective study from January 1999 to January 2001 at Sina hospital 41 patients underwent implantation of 6-mm vascular grafts and 42 underwent implantation of 8-mm grafts in order to make vascular assess for hemodialysi...

Early thrombosis of artificial microvascular grafts (AMG, grafts < or = 2 mm internal diameter) prevents their reliable clinical use. The present studies were undertaken to examine the effect of hirudin, a thrombin-specific inhibitor, and of the F(ab')2 fragment of PG-1, a monoclonal antibody (MoAb) directed against guinea pig platelet membrane glycoprotein Ib (GPIb), on AMG patency in an anima...

UNLABELLED Purpose. We hypothesized that adventitial transplantation of blood outgrowth endothelial cells (BOEC) to the vein-to-graft anastomosis of polytetrafluoroethylene grafts will reduce neointimal hyperplasia by reducing hypoxia inducible factor-1alpha (HIF-1alpha), by increasing angiogenesis in a porcine model of chronic renal insufficiency with haemodialysis polytetrafluoroethylene graf...
