颈动脉内膜剥脱术的临床应用

目的 探讨颈动脉内膜剥脱术的适应证及围手术期处理。方法 回顾性总结11例因短暂性脑缺血(TIA)伴有颈动脉硬化狭窄患者而行颈动脉内膜剥脱术的临床资料。结果 术后所有患者的TIA表现消失，4例慢性脑缺血症状也得到明显的改善。术后未出现偏瘫或脑出血等严重的并发症。结论 对于TIA病人在经Doppler超声或DSA或MRA检查发现-侧或双侧颈总动脉或颈内动脉狭窄大于50％，可以考虑行颈动脉内膜剥脱术。对于双侧颈动脉狭窄者，分期手术治疗较为安全。作好围手术期处理，有助于减少手术并发症发生。

Clinical applicaton of carotid endarterectomy

Objective To study the indications of carotid endarterectomy(CEA) and perioperative managements . Methods The clinical data of 11 patients with transient ischemia attack (TIA) and carotid artery stenosis who underwent CEA were reviewed retrospectively. Results After CEA, the TIA symptoms disappeared in all patients, and the chronic symptoms of cerebral ischemia had obvious improvement in 4 cases . There were no serious postoperative complications, such as cerebral hemorrhage, hemiplegia, etc. Conclusions CEA may be considered when one or both sides of carotid stenosis more than 50% is discovered by Duplex scanning, digital subtraction angiography or MRA in patients with TIA. Stage operation for bilateral carotid occlusive lesion is safer. Paying attention to perioperative managements is important for reducing operative complications.
