目的 研究支架成形术治疗症状性颅内动脉狭窄的可行性和安全性。方法 155例症状性颅内动脉狭窄病人(170处病变 )接受了支架成形术。结果 支架成功率 92. 4% ( 157 /170 ),操作相关并发症率 11.8% ( 20 /170 ), 30d的卒中和死亡率 6. 5% ( 10 /155例 )。临床随访 150例(443d± 271 3d), 30d后的卒中和死亡率为 2 0% (2 /150)。造影随访 44例、49条支架血管,再狭窄率 16% (8 /49)。结论 支架成形术是治疗症状性颅内动脉狭窄可行的方法,但有较高的并发症。为了减少卒中与死亡,需要严格的手术和围手术期措施。尚需进行随机对照研究。
Objective To study the feasibility and safety of stenting in the treatment of symptomatic intracranial arterial stenosis. Methods 155 patients with symptomatic intracranial arterial stenosis (170 lesions) underwent stent-plasty. Results The success rate of stent was 92.4% (157/170), the operation-related complication rate was 11.8% (20/170), and the 30-day stroke and death rate was 6.5% (10/155 cases). Clinical follow-up of 150 cases (443d ± 271 3d), 30d after stroke and mortality was 20% (2/150). Forty-four patients with angiographic follow-up, 49 stents, and restenosis rate of 16% (8/49). Conclusion Stentoplasty is a feasible method for the treatment of symptomatic intracranial arterial stenosis, but has high complication. In order to reduce stroke and death, strict surgical and perioperative measures are required. Need to carry out randomized controlled studies.
