Prospective randomized trial of carotid endarterectomy with primary closure and patch angioplasty with saphenous vein, jugular vein, and polytetrafluoroethylene: perioperative (30-day) results

Abstract

Purpose: The early outcomes of carotid endarterectomy (CEA) with primary closure (PC) versus vein patch closure (saphenous vein [SVP] and jugular vein [JVP]) and polytetrafluoroethylene patch closure (PTFE-PC) were compared.

Methods: Three hundred ninety-nine CEAs were randomized into the following groups: 135 PC, 134 PTFE-PC, and 130 vein patch closure (SVP alternating with JVP). Surviving patients underwent a carotid color duplex ultrasonographic scan 1 month after surgery. Demographic characteristics were similar in all groups.

Results: The incidence of perioperative cerebrovascular accidents (CVAs) was 4.4% for PC, 0.8% for PTFE-PC, and 0% for vein patch closure (PC vs vein patch, p = 0.0165; PC vs all patching [vein and PTFE], p = 0.007). The perioperative CVA and reversible ischemic neurologic deficit (RIND) combined rates for all patching were superior to PC (1.5% vs 5.2%; p = 0.04). These combined rates were also superior for vein patch closure when compared with PC (0.8% vs 5.2%; p = 0.037). The mean diameter of the internal carotid artery was similar in patients who had perioperative neurologic deficits and those who did not. After 1 month of follow-up, 11.9% of the PC arteries were narrowed 50% or more in contrast to 2.3% for PTFE-PC, 3.1% for SVP, and 10.3% for JVP.
