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。
Objective To evaluate the effectiveness and safety of carotid stenting in the treatment of extracranial carotid dissection. Methods Nine patients with extracranial carotid artery dissection were selected and undergone carotid stenting. Postoperative vascular stenosis and dissecting aneurysm were observed. The incidence of perioperative complications was observed. The patients were followed up for 3 months to 1 year . Results The success rate of surgical technique was 100%. The average residual stenosis rate was ≤30%. The average carotid stenosis degree decreased from (75.0 ± 17.6)% to (15.8 ± 9.2)%, and the dissection of the dissecting aneurysm disappeared. Before and after operation, the difference was statistically significant (P <0.05). Patients with postoperative ischemic-related symptoms were significantly improved in all patients during the perioperative symptomatic stroke did not occur, no surgery-related deaths occurred, followed by no ischemic cerebrovascular events, one case of patients with in-stent restenosis . Conclusion Carotid artery stenting is safe and effective in treating extracranial carotid artery dissection.
