目的 :对应用颈动脉内膜剥脱术改善大脑血液循环、预防和治疗缺血性脑卒中进行评价。方法 :1999年10月～ 2 0 0 2年 6月经MRI筛选对 4 6例颈动脉狭窄度超过 5 0 %的患者行颈动脉内膜剥脱术。所有病例均采用颈丛阻滞麻醉 ,对双侧颈动脉均有狭窄者 ,采用术侧颈动脉临时转流术。结果 :随访 2～ 2 4个月 ,4 5例(98.7% )患者术后恢复良好 ,1例 (2 .2 % )术后 30d死于严重心肺功能不全。结论 :严重颈动脉狭窄患者行预防性内膜剥脱术 ,对预防和治疗缺血性脑卒中的发生具有满意的疗效。
Objective: To evaluate the effect of carotid endarterectomy on cerebral blood circulation, prevention and treatment of ischemic stroke. Methods: From October 1999 to June 2002, 46 patients with carotid artery stenosis over 50% underwent carotid endarterectomy. All cases were anesthetized with cervical plexus block, both sides of the narrow carotid artery, the use of temporary carotid artery bypass surgery. Results: Forty-five (98.7%) patients recovered well after 2 to 24 months of follow-up. One patient (2.2%) died of severe cardiopulmonary dysfunction 30 days after operation. Conclusion: The patients with severe carotid stenosis underwent prophylactic endarterectomy, which has a satisfactory effect on the prevention and treatment of ischemic stroke.
