Clinical and Doppler ultrasonography data of a polyurethane vascular access graft for haemodialysis: a prospective study.
BACKGROUND Absence of a permanent vascular access in most patients starting haemodialysis remains a cause of high morbidity and costs. This study obtained new clinical and colour Doppler ultrasound (CDU) data of a polyurethane vascular access graft (PVAG) proposing early post-operative cannulation. METHODS Baseline characteristics were determined in 15 patients and the PVAGs were evaluated pr...
متن کاملVascular access for acute haemodialysis.
Vascular access for acute haemodialysis was required on 29 occasions in 26 children over a six year period. Comparison was made of the forms of vascular access employed, these being the Scribner shunt, the Hickman line, and percutaneous polyvinylchloride cannulae. The Hickman catheter was used to provide vascular access in 17 patients (mean age 8.8 years (range 2.5-16 years) and mean weight 25....
متن کاملBovine ureter graft for haemodialysis access surgery.
Bovine ureter SynerGraft (SG) (CryoLife, Inc.) has been recently introduced into haemodialysis access surgery. It is a non-glutaraldehyde fixed acellular collagen and elastin matrix conduit that may withstand arterial pressures. There has only been one published report in humans with this graft for vascular access, except for a canine model which Matsuura et al. reported [1]. In this study, we ...

متن کاملMaintaining Patency of Vascular Access for Haemodialysis
All types of vascular access, a necessity for haemodialysis, are prone to thrombosis and if untreated this results in failure. Thrombosis results from the combination of impaired blood flow, endothelial and vessel wall injury and a propensity towards pro-coagulative states, either intrinsic or aggravated by dialysis or dehydration. The treatment of access thrombosis relies on removal of the clo...
