目的研究腔内支架成形术治疗症状性颅内动脉狭窄的安全性及有效性。方法对7例症状性颅内动脉狭窄的患者行腔内支架成形术治疗。结果7例患者中6例成功置入8枚冠脉支架,1例因支架置入困难仅行经皮腔内血管成形术(PTA),6例患者术后均未发生脑缺血发作,2例患者术后3～8个月复查经颅多普勒超声(TCD)血流通畅,未见内膜过度增生,1例单纯PTA患者术后症状明显改善,1例基底动脉支架成形术后出现动眼神经麻痹。结论腔内支架成形术是治疗症状性颅内动脉狭窄的安全、有效的方法,其长期疗效还需进一步随防研究。
Objective To study the safety and efficacy of endoluminal stenting in the treatment of symptomatic intracranial arterial stenosis. Methods Seven patients with symptomatic intracranial arterial stenosis underwent endovascular stent thrombolysis. Results Six of the seven patients were successfully treated with eight coronary stents. One patient was treated with percutaneous transluminal angioplasty (PTA) due to stent placement difficulties. Six patients had no postoperative ischemic attack. Two patients Patients underwent repeat transcranial Doppler (TCD) blood flow 3 to 8 months postoperatively with no hyperplasia of the intima, and 1 patient with PTA had significantly improved postoperative symptoms and 1 patient with basilar artery stenting Eye nerve paralysis. Conclusion Endovascular stenting is a safe and effective method for the treatment of symptomatic intracranial arterial stenosis. Long-term curative effect needs to be further studied with prevention.
