title: Recurrent stenosis after carotid endarterectomy.
abstract: Thirteen of 1,250 patients required a second operation for recurrent stenosis following carotid endarterectomy performed at the Cleveland Clinic between 1958 and 1978. Two other patients underwent reoperation because of recurrent stenosis following primary operations at other institutions. Thirteen of the 15 patients experienced neurologic symptoms caused by recurent stenosis, while two patients remained asymptomatic. Atherosclerosis was responsible for recurrent stenosis in 12 patients and appeared to be related to hypercholesterolemia. Three of the patients had myointimal fibroplasia. Eleven of the 16 reoperations for recurrent stenosis of the carotid artery consisted of carotid endarterectomy with vein patch angioplasty. Three patients had carotid endarterectomy with closure of the primary arteriotomy. One patient with occlusion of the internal carotid artery underwent endarterectomy of the external carotid artery because of amaurosis fugax, and a saphenous vein interposition graft was used to replace a previous Dacron graft in one patient with anastomotic stenosis. One patient had a stroke during reoperation manifest as multiple retinal emboli. Fourteen patients have remained asymptomatic from one to 70 months following reoperation. One patient with occlusion of the contralateral internal carotid artery has experienced persistent vertebrobasilar symptoms.
