多支架治疗颅内外动脉狭窄

目的 探讨多支架治疗颅内外动脉狭窄的临床体会。方法 采用2枚或2枚以上支架对8例颅内外动脉狭窄的患者12支狭窄血管行血管成形术，共植入17枚支架，其中颈动脉颅外段狭窄使用自膨胀支架，颅内段和椎动脉使用球囊膨胀型支架。结果 所有患者的手术均成功，术后狭窄均明显改善，随访6～12个月，所有患者均无脑缺血发作，除1例动脉闭塞外，其余无再狭窄发生。结论 多个支架治疗颅内外动脉狭窄安全有效，但仍需长期随访。

Endovascular treatment of intracranial and extracranial arterial stenosis using multiple stents placement

Objective To explore our clinical experience on treatment of intracranial and extracranial arterial stenosis using multiple stents placement. Methods 17 stents were deployed into 12 arteries in 8 patients with intracranial and extracranial arterial stenosis. We utilized self expanding stents in extracranial carotid arteries and balloon expanding stents for intracranial arteries or vertebral arteries. Results All procedures were performed successfully and all stenoses were dilated and improved. Short term follow up angiogram revealed only one vessel occlusion and no significant restenoses in other stented vessels together with no recurence of clinical symptoms. Conclusions Multiple stents placement is a valid alternative for the treatment of intracranial and extracranial arterial stenoses.
