Viabahn覆膜支架在15例下肢动脉疾病腔内治疗中的应用

Application of Viabahn covered stent in endovascular therapy for 15 cases of lower extremity arterial disease

目的探讨Viabahn覆膜支架治疗下肢动脉疾病的可行性、安全性和有效性。方法回顾性分析2015年1月至2015年10月采用腔内治疗15例下肢动脉疾病患者,其中动脉硬化闭塞症11例,医源性损伤2例,动脉夹层1例,车祸伤1例。所有患者在经血管造影明确病变后,植入Viabahn覆膜支架。结果15例患者均手术成功,共植入17枚Viabahn覆膜支架,技术成功率100%,无严重并发症和围手术期死亡,术后临床症状明显改善。术后随访15~24个月,仅有1例再次行球囊扩张术,余14例均未出现相关并发症。结论采用Viabahn覆膜支架进行下肢动脉疾病的血运重建,具有可行性好、安全性高、疗效确切的特点,可为下肢动脉疾病的腔内治疗提供了选择。

Objective To discuss the feasibility, safety and validity of the use of Viabahn covered stent in endovascular therapy of lower extremity arterial disease. Methods During the period from January 2015 to October 2015, a total of 15 pa- tients with lower extremity arterial disease were treated with Viabahn covered stent. The clinical data were retrospective ana- lyzed. The lesions included arteriosclerosis obliterans （n= 11）, iatrogenie injury （n= 2）, arterial dissection （n= 1）, and arte- rial injury （n= 1）. After the diagnosis was confirmed with angiography that was performed, the implantation of Viabahn covered stent was carried out in all patients. Resulls Successful implantation of 17 Viabahn covered stent was accomplished in all 15 cases, with a technical success rate of 100%, and without peri-operative death and severe complications. The symptoms were ameliorated. During the follow-up period of 15-24 months, no stent-related complications occurred in all patients except one patient with iatrogenie injury, who was carried out once more four months after the stent placement. Conclusion The use of Viabahn covered stent in endovascular repair of ower extremity arterial disease is clinically feasible with reliable effect and safety. Therefore, this technique can be employed as a good therapy choice for lower extremity arterial disease.
