Access operation for chemotherapy and dialysis using freeze-preserved vein allografts.

Freeze-preserved vein allografts were used to perform 25 angioaccess operations, 17 for dialysis and 8 for chemotherapy purposes. The freeze preserved vein allograft has proved to be relatively cheap, highly dependable graft material, with a high patency rate and a low incidence of complications. Anticoagulation, while unnecessary in the dialysis patients, is recommended in the oncological group.
