Abstract

The purpose of this study was to determine whether repeat carotid endarterectomy (CEA) poses a greater risk than first-time CEA. The authors analyzed data from 893 consecutive CEA cases (1981-1993). Thirty-three patients (3.7%) had repeat CEA, and 860 (96.3%) had first-time CEA. There were statistically significantly higher incidences of hypertension (60.6% vs 44.6%), smoking (84.8% vs 55%), hypertriglyceridemia (33.3% vs 16.2%), and coronary artery disease (66.6% vs 36%) in the repeat CEA group than in the first-time CEA group. Symptomatic disease was present in 25 (75.8%) patients in the repeat group and in 576 (67%) patients in the first-time group (P=0.05). The cause of recurrence was atherosclerosis in 25 patients (76%), myointimal hyperplasia in seven patients (21.2%), and intraluminal thrombus without an underlying lesion in one patient (3%). Redo CEA with vein patch angioplasty was performed in 27 patients (82%), vein patch angioplasty alone in five patients (15%), and interposition vein graft in one patient (3%). The hospital operative mortality was 0% (n=0) in the repeat CEA group and 0.6% (n=5) in the first-time CEA group (P=0.05). The incidence of postoperative stroke was 0% (n=0) in the repeat group and 1.2% (n= 10) in the first-time group (P=0.05). There was one case (3%) of transient ischemic attack (TIA) in the repeat group, and two cases (0.2%) of TIA in the first-time group. There was no difference in the incidence of cranial nerve dysfunction between the repeat group (n=2, 6%) and the first-time group (n=41, 4.8%; P=0.05). Late follow-up data were obtained for 30 patients (mean: 61.4 months, range: 5-158 months) in the repeat CEA group and 501 patients (mean: 55.8 months, range: 17-168 months) in the first-time CEA group. The incidence of late failure (ipsilateral stroke or TIA) was 3.3% (n= 1) in the repeat group and 3.2% (n= 16) in the firsttime CEA group; P=0.05. The overall late mortality was 20% (n=6) in the repeat CEA group and 14.6% (n=73) in the primary CEA group; P=0.05. Repeat CEA can be performed safely in individuals with severe recurrent carotid stenosis, and perioperative and long-term mortality and neurologic morbidity rates are similar to those for patients undergoing first-time carotid endarterectomy.
