Mo．Ma脑保护装置在颈动脉支架置入术中的效用分析

Short-term efficacy of Mo.Ma proximal cerebral protection during carotid artery stenting

目的探讨颈动脉狭窄支架置人术（CAS）中使用Mo．Ma脑保护装置的价值。方法回顾性分析青岛市中心医院神经内科自2009年3月至2011年9月收治的8例行CAS并使用Mo．Ma脑保护装置的颈内动脉重度狭窄患者的临床资料。结果Mo．Ma脑保护装置保护成功率及CAS手术成功率均为100％，颈内动脉重度狭窄均有改善，残余狭窄率均低于30％：1例回抽血液中见捕获的小斑块，无患者发生栓子脱落事件；术后复查头部MRJ，未发现新发的缺血病灶：术后1个月复查颈部血管彩超均未发现再狭窄。结论对颈内动脉重度狭窄的患者行CAS时，使用Mo．Ma脑保护装置安全、有效，但仍需大样本病例进～步证实。

Objective To investigate the safety and effectiveness of Mo.Ma proximal cerebral protection device during carotid artery stenting （CAS）. Methods Eight patients with high-grade carotid artery stenosis, admitted to and underwent carotid artery stenting using Mo.Ma cerebral protection device in our hospital from March 2009 to September 2011, were chosen in our study; their clinical data were retrospectively analyzed. Results The device success rate and procedural success rate were 100%, and the residual stenosis was less than 30%. The debris was captured in the aspirated blood in one patient. No patient had deficit caused by emboli. No new ischemic lesions were found in post-operative MRI-diffused weighted imaging, and no restenosis was noted under neck vascular ultrasound one month after the operation. Conclusion The Mo.Ma proximal cerebral protection device is safe and effective for patients with high-grade internal carotid stenosis undergoing carotid artery stenting, but the orosoective multicenter registry trials need to date.
