显微颈动脉内膜切除术

目的评估显微颈动脉内膜切除的效果。方法回顾1998年至2004年4月施行的92例96侧显微颈动脉内膜切除的手术并发症,并分析其原因。结果与手术直接相关的并发症包括TIA1例、脑卒中2例、轻度颅神经损害3例、假性动脉瘤1例,但均非手术操作缺陷所致。死亡1例。结论颈动脉内膜切除的缺血性并发症多与手术操作不当相关,采用显微外科技术可以降低此类并发症率。显微外科技术还有助于远端颈内动脉显露和降低颅神经损伤发生率。

Microsurgical carotid endarterectomy

Objective To evaluate the beneficial effects of microsurgical carotid endarterectomy. Methods From 1998 to April 2004 ninety-six sides of microsurgical carotid endarterectomy were performed in ninety-two patients with atherosclerotic carotid stenosis. The surgical complications and their causes were analysed. Results The complications directly related to the surgery included one case of TIA, two cases of stroke, three cases of mild cranial nerve palsy and one case of pseudoaneurysm. All these complications were not the results of technical failures. One patient died after the second operation. Conclusion Most ischemic complications after carotid endarterectomy result from technical failures. Microsurgical technique is useful for decreasing such complications and the rate of cranial nerve injury, and promoting the exposure of distal internal carotid artery.
