title: Autogenous profundaplasty: The key to long-term patency in secondary repair of aortofemoral graft occlusion.
abstract: The records of 281 patients undergoing aortic grafting to 522 femoral arteries over a period of 18 years were reviewed. Fifty-four patients suffering graft limb occlusion to 71 femoral arteries requiring subsequent secondary repair were identified for detailed analysis. Occlusive disease of the profunda femoris artery was identified as the primary cause of thrombosis. Repair consisted of profunda femoris angioplasty, and transfemoral retrograde graft thrombectomy was possible in all but three instances which were managed by cross-over femoral-femoral bypass. In no instance was laparotomy and abdominal graft replacement necessary. The 30 day operative survival and graft patency were 100%. Analysis of factors that have influenced late graft patency demonstrated that the key factors were the method of profundaplasty and the association of diabetes mellitus. When autogenous profundaplasty (on-lay arterial patches, saphenous vein, or limited endarterectomy) was employed, the overall patency combining diabetics and non-diabetics was two and one-half times greater than when profundaplasty was performed with an on-lay Dacron((R)) patch. If diabetics were separated from nondiabetics in the autogenous angioplasty group, the 36 month patency for non-diabetics was 85%, and 0% for diabetics. We conclude that autogenous profundaplasty provides considerable advantage from the standpoint of long-term patency and that the diabetic patients are relatively poor candidates for secondary arterial repair of an occluded aortofemoral bypass graft.
