Abstract：
Iliac vein stenting for the treatment of iliac vein compression syndrome (IVCS) has been gradually developed. This article investigated the long-term patency and improvement of clinical symptoms after endovascular stenting for iliac vein obstruction patients. From 2020 to 2022, 83 patients at a single institution with IVCS underwent venous stent implantation and were divided into two groups: non-thrombotic IVCS (n = 55) and thrombotic IVCS (n = 28). The main stent-related outcomes include technical success, long-term patency, and thrombotic events. The technical success rate of all stent implantation was 100%. The mean length of hospital stay and cost were higher in the thrombotic IVCS group than in the non-thrombotic ICVS group, as well as the length of diseased vessel segment and the number of stents implanted were higher than in the control non-thrombotic group. The 1-, 2-, and 3-year patency rates were 85.4%, 80% and 66.7% in the thrombosis group, which were lower than 93.6%, 88.7%, and 87.5% in the control group (P = .0135, hazard ratio = 2.644). In addition, patients in both groups had a foreign body sensation after stent implantation, which resolved spontaneously within 1 year after surgery. Overall, there were statistically significant differences in long-term patency rate outcome between patients with thrombotic and non-thrombotic IVCS, the 1-, 2-, and 3-year patency rates in non-thrombotic IVCS patients were higher than those in thrombotic IVCS patients.
摘要：
用于治疗髂静脉压迫综合征(IVCS)的髂静脉支架已逐渐发展。本文探讨了髂静脉阻塞患者血管内支架置入术后的长期通畅性和临床症状的改善情况。从2020年到2022年，一个机构的83例IVCS患者接受了静脉支架植入，分为两组：非血栓性IVCS（n=55）和血栓性IVCS（n=28）。与支架相关的主要结果包括技术成功，长期通畅，和血栓事件。所有支架植入术的技术成功率为100%。血栓性IVCS组的平均住院时间和费用高于非血栓性ICVS组，病变血管段的长度和植入支架的数量均高于非血栓形成对照组。1-,2-,3年通畅率为85.4%，血栓形成组的80%和66.7%,低于93.6%，88.7%,对照组为87.5%（P=0.0135，风险比=2.644）。此外,两组患者在支架植入后都有异物感,在手术后1年内自发解决。总的来说,血栓性和非血栓性IVCS患者的长期通畅率结果差异有统计学意义,1-,2-,非血栓性IVCS患者的3年通畅率高于血栓性IVCS患者。
