title: [Prosthetic bypasses: can we improve the results?].
abstract: Two hundred and forty-five polytetrafluorethylene (PTFE) grafts have been followed up for 6 months to 10 years. There were 56 failures (23%), the main 4 problems being, in chronological order, technical errors, anastomotic hyperplasia, plications and the spread of the disease. Each of these complications is studied and an original technique aimed at preventing them is described. This consists in widening the distal anastomosis with a venous patch forming the distal end of the anastomosis and extending upstreams to a longitudinal and median incision in the PTFE.
