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 (PC vs all patching, p = 0.008; PC vs PTFE-PC, p = 0.0017; PC vs SVP, p = 0.028). In contrast, early postoperative dilation of the internal carotid artery to more than twice the measured diameter was not significantly higher in patched arteries than in PC arteries. The mean operative and hemostasis times were significantly longer for patching than for PC. Conclusions: Patch closure is less likely than PC to cause perioperative CVA, RIND, and early internal carotid artery stenosis. (J Vasc Surg 1996;24;998-1007.) |
