title: Clinical experience with circumferentially reinforced expanded polytetrafluoroenthylene (E-PTFE) graft as a vascular access for haemodialysis.
abstract: Circumferentially reinforced E-PTFE grafts were implanted 50 times in 46 patients. Seven grafts became occluded during the observation period of 233 patient-months. Puncture and haemostasis were quite satisfactory in the majority of the patients. Histologically, the inner surface of the grafts was covered with a thin fibrin layer. Puncture sites were stuffed with fibro-fibrinous tissue preventing bleeding or aneurysmal dilatation. Clinical experience has proved the E-PTFE graft to be a suitable vascular prosthesis for blood access.
