摘　　要：目的观察颈动脉内膜切除术（CEA）后对侧颈内动脉变化情况。方法回顾性分析127例因一侧颈内动脉高度狭窄而实施CEA病人的临床资料,每隔1年行1次双侧颈动脉超声检查,定期检查双侧颈动脉狭窄情况。结果随访1~110个月,平均32.8个月,从实施CEA到对侧颈内动脉出现显著狭窄时间为50.7个月;出现对侧颈内动脉进行性狭窄达70%以上12例。这12例虽合并高血压、高脂血症或冠脉疾病,但与非进行性狭窄病人经统计学分析无显著差异（P〉0.05）。结论 CEA术后对侧颈内动脉出现进行性狭窄的显著危险因子尚未发现,定期检查及密切观察预后非常重要。Objective To observe the change of contralateral internal carotid artery after carotid endarterectomy（CEA）.Methods The clinical data of 127 patients with high-grade stenosis in one side of internal carotid endartenectomy who underwent CEA were analyzed retrospectively.The ultrasonic testing of bilateral carotid arteries was performed on all the patients every 2 years to examine the stenosis in bilateral carotid arteries.Results All the patients were followed up for 1 to 110 months with a mean period of 32.8 months.It was about 50.7 months from the implementation of CEA to the appearance of significant stenosis in contralateral carotid artery.The contralateral carotid artery progressive stenosis which came up to 70% occured in 12 patients.There was no significant difference between patients with nonprogressive stenosis and 12 patients with progressive stenosis,although these patients had hypertension,hyperlipidemia or coronary diseases（P0.05）.Conclusions The significant risk factors which may cause progressive stenosis in contralateral internal carotid artery after CEA have not been discovered.The regular inspections and close observation of prognosis are very important.
