Retrospective Clinical Observation Of Bypasses To Femoral Or Popliteal Arteries In Lower Extremities With Arteriosclerosis Obliterans

AIMS: Bypasses to femoral and popliteal arteries can effectively revascularize and salvage the severely ischemic lower extremity with arteriosclerosis obliterans. Both ePTFE and autogenous greater saphenous vein can be the substitute. In this article, a restropective observation is performed on the clinical effect of bypasses to femoral and popliteal arteries with ePTFE and autogenous greater saphenous vein seperately to investigate the advantages and disadvantages of them as grafts and to provide basis for clinical use.Methods: Fifty-seven cases with arteriosclerosis obliterans are chosen that underwent bypasses to femoral and popliteal arteries during the period of 2004 Nov. to 2007 Jan. in our hospital and divided into two groups according to the grafts. There are 41 cases in Group ePTFE and 16 cases in Group SV. A retrospective observation is performed on the scales of symptom-relief and patency of the bypasses.Results: Artrial bypasses can effectively relieve the symptoms of patients with arteriosclerosis obliterans. The patency rate of ePTFE is 80.49% and for autogenous greater vein is 93.75%.Conclusions: Artrial bypasses can effectively revascularize and salvage the severely ischemic lower extremity with arteriosclerosisobliterans. Autogenous greater vein is superior to ePTFE as graft on patency. SV is the first choice for bypasses to femoral and the distal arteries and ePTFE is used for proximal arteries upon the inguinal ligment.
