Multiple nonanastomotic aneurysms in an external velour ringed Dacron femoropopliteal vascular prosthesis.

Nonanastomotic aneurysms of arterial prosthetic grafts are an infrequent but well-documented complication of arterial bypass surgery. Several cases of nonanastomotic aneurysm formation of the external velour-type Dacron graft have been reported. We present a case of an external velour ringed Dacron (Sauvage EXS) femoropopliteal bypass graft with multiple nonanastomotic aneurysms. An extensive review of the English literature shows this to be the first reported case of multiple aneurysms occurring in this type of prosthesis.
