血管内支架成形术在症状性脑血管狭窄治疗中应用的初步探讨

目的探讨血管内支架成形术治疗症状性脑动脉狭窄的效果及安全性。方法对33例症状性脑动脉狭窄患者进行了37处血管内支架成形术治疗,其中颈内动脉颅外段狭窄14处,颈内动脉颅内段狭窄3处,大脑中动脉狭窄3处,椎动脉颅外段狭窄13处,椎动脉颅内段2处,锁骨下动脉2处。结果本组33例患者行37处支架置入术,其中成功置入35枚支架,手术成功率94.59%;1例手术中并发脑血管痉挛,1例手术中并发造影剂过敏,1例手术后并发高灌注综合征。结论血管内支架成形术治疗症状性脑动脉狭窄是安全有效的,其远期疗效尚待进一步随访观察。

Therapeutic effect observation of endovaseular stent-assisted angioplasty to treat brain artery stenosis

Objective To observe the effect and feasibility of endovaseular stent-assisted angioplasty to treat brain artery stenosis.Methods Endovaseular stent-assisted angioplasty was performed in 33 patients with brain artery stenosis,including 14 cases of extracranial ternal carotid artery stenosis,3 cases of intracranial internal carotid artery stenosis,3 cases of middle cerebral artery stenosis,13 cases of extracranial vertebral artery stenosis,2 cases of intracranial vertebral artery stenosis and 2 cases of subclavian artery stenosis.Results Among 33 patients,35 of 37 stents were implanted successfully（94.59%）.The complications include angiospasm,radiography medicament allergy and hyperperfusion syndrome in 3 patiens.Conclusion Endovaseular stent-assisted angioplasty is a effective methed to treat intraeranial artery stenosis,however the long-term effect needs to evaluate by flow-up.
