Polytetrafluoroethylene grafts for carotid repair.
Polytetrafluoroethylene grafts are well established for bypassing occlusive disease in the lower limb but there are few reports which deal with the long-term results of such grafts in the neck. The present study was undertaken to evaluate the immediate and long-term results of polytetrafluoroethylene grafts for carotid repair. Between 1982 and 1991, 591 carotid operations (mostly endarterectomies) were performed by the authors. In 32 cases a polytetrafluoroethylene graft was used to replace (n = 12) or to bypass (n = 20) a stenotic lesion of the internal carotid artery. Postoperative angiography was obtained in all patients and the follow-up extended from 1 month to 9 years (mean 30 months) with clinical and duplex scan surveillance. There were no deaths within the first postoperative month. There was one acute postoperative stroke (3%) caused by plaque dislodgement and one symptomless occlusion demonstrated by routine angiography. During follow-up, seven patients died from other causes. No patient developed new neurological symptoms but routine duplex assessment showed one symptomless graft occlusion. The cumulative survival rate was 96% at 1 year and 91% at 4 years. The cumulative primary patency rate was 93% at 1 month, 89% at 1 year and 89% at 4 years. In specific situations polytetrafluoroethylene grafting is an adequate alternative to carotid endarterectomy but is not recommended by the authors as a routine procedure because of its occlusion rate (> 6.2%).
