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25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25例患者中24例成功置入26枚冠脉支架,1例因支架置入困难仅行PTA术。22例患者术后均未发生脑缺血发作,1例单纯PTA患者术后症状明显改善,1例患者术后9个月复查TCD可见内膜增生,1例基底动脉支架成形术后出现动眼神经麻痹,1例出现再灌注损伤。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 Twenty-five patients with symptomatic intracranial arterial stenosis underwent endovascular stent-graft. Results Twenty-six coronary arteries were successfully implanted in 24 of 25 patients, and only one of them was treated with PTA because of difficulties in stent placement. Twenty-two patients had no ischemic postoperative ischemic attack. One patient with PTA had significantly improved postoperative symptoms, one patient had a neointimal hyperplasia at TCD 9 months after operation, and one patient with basilar artery angioplasty Neurological paralysis, 1 case of reperfusion injury. 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.
