颈动脉支架成形术治疗颅外段颈动脉夹层的疗效观察

目的 评价颈动脉支架成形术治疗颅外段颈动脉夹层的有效性及安全性。方法 选择颅外段颈动脉夹层患者9例,均行颈动脉支架成形术,观察术后血管狭窄及夹层动脉瘤改善情况,围术期并发症的发生情况,对患者随访3个月到1年。结果 手术技术成功率为100%,术后平均残余狭窄率均≤30%,患者颈动脉平均狭窄程度从(75.0±17.6)%降低至(15.8±9.2)%,夹层动脉瘤均消失,支架置入手术前后比较,差异有统计学意义(P<0.05)。患者术后缺血相关症状均有明显改善,围术期所有患者均未出现症状性脑卒中,无手术相关死亡事件发生,随访无缺血性脑血管事件发生,1例患者可见支架内再狭窄。结论 颈动脉支架成形术治疗颅外段颈动脉夹层安全、有效。

Evaluation of endovascular stenting for extracranial carotid artery

ObjectiveTo evaluate the efficacy and safety of stenting for extracranial carotid artery dissection.Methods 9 patients with extracranial carotid artery dissection admitted in our center underwent stenting procedure. Post-operational stenosis, aneurysm obliteration and perioperative complications were evaluated. Clinical follow-ups were done within 3 to 12 months.Results Satisfactory stent deployment and aneurysm occlusion were achieved in all these 9 patients. The mean carotid artery stenosis was significantly reduced from(75.0±17.6)% to(15.8±9.2)%, with the mean residual stenosis rate less than 30%(P<0.05). Ischemic symptoms were relieved after the procedure for all the patients. No perioperative symptomatic stroke, procedure-related death or ischemic cerebrovascular events were observed during the follow-up period. In-stent restenosis was observed in 1 patient.Conclusion It is safe and effective to treat extracranial carotid artery dissection by endovascular stenting.
