目的探讨颈动脉狭窄患者颈动脉血管成形和支架置入术(CAS)中应用脑保护装置的有效性和安全性。方法颈动脉狭窄患者CAS治疗时,12例应用脑保护装置(滤网型),16例未使用脑保护装置。结果28例颈动脉狭窄患者成功释放31枚自膨式支架。未使用脑保护装置组球囊预扩1次(6·2%),无一例后扩;使用脑保护装置组球囊预扩4次(33·3%),后扩6次(50%)。CAS治疗中,7例(25·0%)患者出现短暂性心率减慢和低血压。回收的脑保护装置中2例(16·7%)肉眼可见组织碎片。使用脑保护装置组在围手术期和随访期无神经并发症;未使用脑保护装置组围手术期发生1例(6·3%)脑梗死,随访期发生1例(6·3%)脑梗死。结论脑保护装置的使用有助于减少颈动脉狭窄患者CAS治疗的神经并发症。
Objective To investigate the effectiveness and safety of brain protection device in carotid angioplasty and stent implantation (CAS) in patients with carotid artery stenosis. Methods CAS treatment in patients with carotid artery stenosis, 12 cases of brain protection device (filter type), 16 cases did not use brain protection device. Results Twenty-eight patients with carotid stenosis were successfully released 31 self-expanding stents. In the brain protection device group, the balloon was pre-expanded 1 time (6.2%) without any posterior extension. The brain protection device was used to pre-expand the balloon 4 times (33.3%) and then expanded 6 times (50% . CAS treatment, 7 patients (25.0%) patients with transient heart rate slowdown and hypotension. Two (16.7%) of the brain protection devices recovered showed macroscopic tissue fragments. There was no neurological complications during the perioperative and follow-up periods in the brain protection device group. One patient (6.3%) developed cerebral infarction during the perioperative period without cerebral protection device group, and one (6.3%) brain occurred during the follow-up period Infarct. Conclusion The use of brain protection devices can help reduce the neurological complications of CAS therapy in patients with carotid artery stenosis.
