摘　　要：目的：探讨血管内支架成形术治疗颅内动脉狭窄的可行性及疗效。材料和方法：对27例症状性颅内动脉狭窄行血管内支架成形术,其中颈内动脉颅内段狭窄8例、大脑中动脉狭窄11例、基底动脉狭窄1例和椎动脉颅内段狭窄7处。结果：27例中,支架成形术成功26例(96．3%),狭窄程度从术前76．3±10．1%降至术后8．2±6．9%。其中1例因颈内动脉虹吸段过度迂曲导致支架植入失败,2例术后24h内发生颅内出血,1例术后发生支架内血栓再形成,无手术死亡。22例随访0．5～1a(平均7．5个月),无缺血性脑卒中发生。结论：血管内支架成形术是治疗颅内动脉狭窄的有效方法,具有较高的成功率及一定的安全性,但长期疗效有待于进一步随访。Purpose： To observe the effect and feasibility of endovascular stem-assisted angioplasty to treat intracranial artery stenosis. Materials and Methods： Eendovascular stent-assisted angioplasty was performed in 27 cases with intracranial artery stenosis, including 8 cases of intracranial internal carotid artery stenosis, 11 cases of middle cerebral artery stenosis, 1 cases of basilar artery stenosis and 7 cases of intracranial vertebral artery stenosis. Results 26 cases had perform Endovascular stent-assisted angioplasty successfully, one was failure to perform the endovascular angioplasty because of uninflexion in petrous segment of internal carotid artery, the mean preoperative stenosis of（76.3 ±10.1）% reduced to（8.2 ±6.9）% after endovascular angiop lasty, only one case recurred thrombosis in vascular after PTAS,none died. During six-twelve mon （ mean 7.5mon） flow-up,22 cases did not curre ischemic stroke. Conclusion： Endovascular stent-assisted angioplasty is a effective methed to treat intracranial artery stenosis,however the long-term effect needs to evaluate by flow-up.
