对吻式支架在慢性髂腔静脉闭塞中的应用

The application of kissing-stent in treatingg chronic iliac-vena cava occlusion

目的 评估对吻式支架治疗慢性髂腔静脉闭塞的临床疗效。方法 回顾性分析接受对吻式支架治疗的22例慢性髂腔静脉闭塞患者的临床资料,观察手术成功率及相关并发症,统计术后3、6、12个月的支架通畅率,比较术后6个月的Villalta评分变化。结果 对吻式支架成功置入率为100%。未发现相关手术并发症。术后3、6、12个月的通畅率分别为95.5%、90.9%、86.1%。术后6个月的Villalta评分为(12.14±2.80)分,明显低于术前的(20.91±3.16)分,差异有统计学意义(P<0.05)。结论 对吻式支架可成功重建髂腔静脉,治疗慢性髂腔静脉闭塞的短期疗效较好。

I Objective To evaluate the clinical efficacy of kissing-stent implantation in the treatment of chronic iliac-vena cava occlusion.Methods The clinical data of 22 patients with chronic iliac-vena cava occlusion,who received kissing-stent implantation,were retrospectively analyzed.The surgical success rate and the procedure-related complications were recorded,the postoperative 3-,6-and 12-month stent patency rates were calculated,and the postoperative 6-month Villalta score was compared with its preoperative value.Results The technical success rate of kissing-stent implantation was 100%.No procedure-related surgical complications occurred.The postoperative 3-,6-and 12-month stent patency rates were 95.5%,90.9%and 86.1%respectively.The postoperative 6-month Villalta score was(12.14±2.80)points,which was remarkably lower than preoperative(20.91±3.16)points,the difference was statistically significant(P<0.05).Conclusion The implantation of kissingstent can successfully reconstruct iliacvena cava with satisfactory short-term efficacy for chronic iliacvena cava occlusion.
