Abstract:

Objective To investigate the application of standard and eversion carotid endarterectomy for carotid artery stenosis in clinical practice. Methods The clinical data of 265 patients with carotid stenosis(11 of them underwent bilateral operation at two different stages. Each patient was calculated as 2; therefore, there was a total of 276 patients) treated with carotid endarterectomy from April 2008 to October 2011 were analyzed retrospectively. Our study had 80 cases undergoing standard carotid endarterectomy(sCE) and 196 cases treated with eversion carotid endarterectomy(eCEA). Clamp time, nerve injury rate, remission rate, restenosis rate and application of bypass pipe were analyzed retrospectively. Results There were no significant differences in the clamp time(sCEA[25.3±11.2]min vs eCEA [23.1±9.8]min, P=0.106), nerve injury rate(sCEA[3.75%] vs eCEA[6.12%], P=0.62), remission rate(sCEA[95.00%] vs eCEA[96.93%], P=0.669) between both groups. During the operation, there were 12 patients who used bypass pines. There was significant difference in the restenosis rate between both groups. Two cases treated with sCEA developed restenosis(2.50%), and none treated with eCEA developed restenosis(P=0.026). No ischemic stroke occurred in both groups after a follow-up period ranging from 3 to 35 months. Conclusion Both sCEA and eCEA can effectively treat carotid artery stenosis.
