颈动脉次全闭塞患者支架置入术效果分析

Effect analysis of stenting in patients with in subtotal occlusion of internal carotid artery

目的探讨颈动脉次全闭塞患者行支架置入术的可行性及安全性。方法回顾性分析首都医科大学宣武医院2014年12月至2016年7月6例诊断为颈动脉次全闭塞并行支架置入术患者的临床资料。结果 6例患者均成功接受颈动脉支架置入术,狭窄率由术前95%-99%降至术后的0-20%。术中均采用近端保护装置MO.MA,1例患者术中出现短暂性脑缺血发作症状,1例患者术后头部MRI示有新发脑梗死,患者术后均未出现神经功能缺损的临床症状。随访3个月,1例患者发生轻度再狭窄（狭窄率〈50%）。结论对颈动脉次全闭塞患者行支架置入术,技术上安全可行,采用近端保护装置可能有助于预防术中栓塞事件。

Objective To investigate the feasibility and safety of stenting in patients with subtotal occlusion of internal carotid artery. M ethods The clinical data of 6 patients diagnosed as subtotal embolization with carotid artery stenting in Xuanwu Hospital,Capital Medical University from December2014 to July 2016 were analyzed retrospectively. Results All 6 patients received carotid artery stenting.The stenosis rate was reduced from 95%-99% before procedure to 0-20% after procedure. The proximal protection device MO. MA was used during the operation. One patient had transient ischemic attack during the operation. Head MRI revealed that 1 patient had new cerebral infarction after procedure. All patients did not have any clinical symptoms of neurological defect after procedure. One patient had mild restenosis（ rate of stenosis 50%） in the 3-month follow-up observation. Conclusions Stenting for patients with subtotal occlusion of carotid artery is technically safe and feasible. The use of proximal protection device may contribute to the prevention of intraoperative embolic events.
