非血栓性髂静脉狭窄支架成形术对深静脉瓣膜功能的影响

目的 探讨髂静脉支架成形术对非血栓性髂静脉压迫病变（NIVCL）患者深静脉瓣膜功能的影响。方法 收集2015年 4月~2018年4月我院血管外科22例行髂静脉支架成形术治疗的NIVCL合并下肢深静脉瓣膜反流患者的临床资料及随访结果，其中21例左侧髂静脉狭窄，1例右侧髂静脉狭窄，比较患者手术前后深静脉瓣膜反流持续时间（VCT）及静脉疾病严重程度评分（VCSS）。结果 22例患者手术均成功，成功率100.00%，术后无支架闭塞、下肢感染和深静脉血栓形成等严重并发症。术后3个月随访时，一期支架通畅率100

Effect of Non-thrombotic Iliac Vein Stenosis on Deep Venous Valve Function

Objective To investigate the effect of iliac vein stenting on deep venous valve function in patients with non-thrombotic iliac vein compression(NIVCL).Methods From April 2015 to April 2018, 22 patients with vascular surgery in our hospital underwent iliac vein stenting for clinical data and follow-up of NIVCL with deep venous valve regurgitation. 21 patients had left iliac vein stenosis. One patient had a right iliac vein stenosis. The duration of deep venous regurgitation (VCT) and venous disease severity score (VCSS) were compared before and after surgery.Results All the 22 patients were successfully operated with a success rate of 100.00%. There were no serious complications such as stent occlusion, lower limb infection and deep vein thrombosis. At 3 months follow-up, the first-stage stent patency rate was 100.00%, the swelling relief rate was 83.30%, and the ulcer healing rate was 80.00%. The VCT of the patients decreased 3 months after operation (1.68±1.67) s vs (2.46±1.36) s], the difference was statistically significant(P<0.05); the VCSS score decreased 3 months after surgery (5.00±1.54) score vs(5.59±2.13)score], the difference was statistically significant(P<0.05).Conclusion The iliac vein stenting is a safe and effective treatment for NIVCL, which has a significant improvement on mild deep venous insufficiency.
