摘要
目的应用颈动脉内膜切除术改善大脑循环并预防缺血性脑卒中。方法 1995年 12月至 2 0 0 0年 12月对经核磁血管成像 (MRA)筛选的 30例颈动脉狭窄度超过 5 0 %患者行颈动脉内膜切除术。所有病例均采用颈丛神经阻滞麻醉 ,阻断颈动脉前 ,测定残端指数 (SI)。对于先前有严重脑功能障碍者 ,对侧颈动脉闭塞者及SI <40者使用颈动脉临时转流术。结果随访 3～ 36个月 ,97%(2 9/30 )患者术后恢复良好 ,1例患者术后 30d死于肺部感染、严重心肺功能不全。
ObjectiveTo prevent late cerebral ischemic stroke by carotid endarterectomy (CEA). Methods From Dec. 1995 to Dec. 2000, CEA was performed under local anaesthesia for 30 patients with more than 50% of carotid stenosis detected by MRA. Stemp index (SI) was measured before carotid was clamped. Temporary intraluminal shunts were used in cases with demonstrated contralateral carotid occlusion, prior cerebrovascular accident (CVA), or SI less than 40. Results At follow-up of 3～36 months, 97%(29/30) patients were at satisfactory condition, and one died perioperatively from cardiac insufficiency, and severe respiratory infection.Conclusion CEA effects a definite prevention for cerebral stroke in patients with severe carotid stenosis.
