[Bypass on a single major artery of the leg. Theoretical modalities and results apropos of 100 cases].
Sub-crural bypass operations on a single leg artery were analysed retrospectively with a follow-up period ranging from six months to eight years. The vitality of the limb was threatened in the majority of cases (91/96). Whenever possible (79/96) the internal saphenous vein was used as a graft, preferably by the in situ technique. Mortality was 6%. Morbidity with the exception of thromboses was 14.5%. Patency by actuarial analysis was 71.6% at 5 years and 65.8% beyond. The majority of thromboses occurred during the first few months and led, in the majority of cases, to amputation. Secondary thromboses were better tolerated. The influence of various parameters was studied: clinical stage, peroperative flowmeter results, material used, technique, associated procedure (sympathectomy), implantation site and permeable vessel.
