目的:观察颈动脉支架植入治疗颈动脉狭窄的疗效及其安全性。方法:12例颈动脉狭窄患者进行了经皮腔内血管成形和支架植入术治疗。结果:所有患者均经DSA血管造影证实有颈内动脉狭窄,手术成功率100%,治疗后残余狭窄率均低于30%。12例患者中有1例出现术中球囊扩张时对侧肢体局灶性癜痫发作;2例血管痉挛;8例出现术中低血压、心动过缓;3例发生于术后低血压;1例出现术后高灌注综合征。结论:血管内支架成形术是一种治疗颈动脉狭窄安全有效的方法,提高术者操作技巧及围手术期监护可以降低手术并发症和死亡率,提高安全性。
Objective: To observe the efficacy and safety of carotid artery stenting in the treatment of carotid artery stenosis. Methods: Twelve patients with carotid artery stenosis underwent percutaneous transluminal angioplasty and stent implantation. Results: All patients had internal carotid artery stenosis confirmed by DSA angiography. The successful rate of surgery was 100%. The residual stenosis rate was less than 30% after treatment. One of the 12 patients had focal edema on the contralateral limb during balloon dilatation; 2 cases of vasospasm; 8 cases of intraoperative hypotension and bradycardia; 3 cases of postoperative hypotension; One case had postoperative hyperperfusion syndrome. Conclusion: Endovascular stenting is a safe and effective method for the treatment of carotid artery stenosis. Improving operative skills and perioperative monitoring can reduce the complications and mortality and improve the safety.
