[Stenosis of hemodialysis grafts. Treatment with a short graft].

In elective or emergency operations 363 short venous or polytetrafluoroethylene grafts were inserted to correct stenosis of haemodialysis grafts. Such stenoses are located in the upper part of the graft or in the receiving vein in 80% of the cases. After 2 years, 74% of the short grafts were still permeable. This original technique has several advantages: the initial venous approach is respected, the graft can be used immediately for dialysis, and the patient's venous "capital" is spared.
