颈动脉内膜切除术的临床应用

Clinical Application of Carotid Endarterectomy

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：回顾性总结18例因短暂性脑缺血（TIA）伴颈动脉狭窄患者而行颈动脉内膜切除术的临床资料。结果：术后所有患者TIA症状消失，TCD显示脑血流量明显提高，随访6～24个月症状无复发。结论：对于严重颈动脉狭窄患者行颈动脉内膜切除术可有效预防脑卒中的发生，严格掌握适应证是提高疗效及减少并发症的关键。

Objective： To prevent late cerebral icchemic stroke by canotid endarterectomy（CEA）. Method： The clinical date of 18 patients with transient ischemic attack（TIA） and carotid artery stenosis who underwent CEA were reviewed. Results： After CEA, the TIA symptoms disappeared in all patients. The cerebral blood flow was improved obviously by TCD. In 6 - 24 months followed up： none of the patients suffered from severe complication and TIA. Conclusion： CEA possess a definite prevention for cerebral stroke in patients with severe carotid stenosis. Appropriate patients choiced selectively help to reduce the occurrence of postoperative complication.
