Stretch polytetrafluoroethylene grafts for hemodialysis angioaccess three-year experience

الملخص EN

We report the results of 90 stretch polytetrafluoroethylene (PTFE) grafts in 78 chronic renal failure patients over a 3-year period from 1995-1998.

The grafts were used as primary access in 15 % of the patients.

The cumulative patency was 63.3 % and there were no complications in 48.8 % of the cases.

Infection was encountered in 15.5 % and thrombosis in 31.1 % of the grafts.

Intimal hyperplasia, venous anastomotic stenosis, improper puncture technique and subclavian vein stenosis were the major causes of failure of grafts.

We conclude that stretch PTFE grafts as angioaccesses may provide good patency and durability.
