■目的是分析技术,临床,和我们的恶性上腔静脉综合征(SVCS)患者的生存结局,并分析不同类型支架的疗效。
■它是一种观测,回顾性,单中心研究。从2006年到2023年,42名患者(32名男性,10女,平均年龄62岁,年龄范围,41-87岁)接受了恶性SVCS的经皮支架置入术。1个不锈钢支架(Wallstent)和2个静脉镍钛诺支架类型(Sinus-XL,Venovo)被使用。平均随访时间为276天。
■共部署了53个支架。不到24小时的临床成功率为97.6%。技术成功率为97.6%。除1例患者因支架迁移和心房分离而死亡外,无并发症发生(2.3%)。术中支架总移行率为11.9%(18.8%不锈钢支架,9.6%镍钛诺支架,p>0.05)。总生存率为87.8%,41.99%,34.12%,总体原发性通畅率为100%,93.3%,在1个月、6个月和12个月时为91.6%,分别。
■血管内治疗是一种安全有效的SVCS治疗选择,技术和临床成功率高,并发症和复发率低。
结论:恶性上腔静脉综合征是一种罕见的临床实体,通常用放疗和化疗治疗,反应较慢,或者手术旁路,这是一种积极的手术技术。血管内治疗提供了一种低侵入性技术,具有快速的临床分辨率和良好的渗透性结果。然而,缺乏对程序技术特征的进一步研究,使用的支架类型,技术并发症,以及中长期通畅性研究。本研究旨在评估所有这些项目,分析自膨式不锈钢和镍钛诺静脉裸金属支架,为血管内治疗增加价值,证实了这项技术的良好结果。
UNASSIGNED: The purpose was to analyze the technical, clinical, and survival outcomes of our patients with malignant superior cava vein syndrome (SVCS) treated with endovascular approach and analyze the efficacy of different stent types used.
UNASSIGNED: It is an observational, retrospective, single-center study. From 2006 to 2023, 42 patients (32 male, 10 female, mean age 62 years, age range, 41-87 years) underwent percutaneous stent placement for malignant SVCS. One stainless steel stent (Wallstent) and 2 venous nitinol stent type (Sinus-XL, Venovo) were used. Follow-up mean was 276 days.
UNASSIGNED: A total of 53 stents were deployed. Clinical success was 97.6% in less 24 hours. Technical success was achieved in 97.6%. No complications were found except 1 patient died during the procedure due to stent migration and atrial dissociation (2.3%). Overall intraprocedural stent migration rate was 11.9% (18.8% stainless steel stent, 9.6% nitinol stent, p>0.05). Overall survival rates were 87.8%, 41.99%, and 34.12%, and overall primary patency rates were 100%, 93.3%, 91.6% at 1, 6, and 12 months, respectively.
UNASSIGNED: Endovascular treatment is a safe and effective therapeutic option for SVCS with high technical and clinical success rates and low complication and recurrence rates.
CONCLUSIONS: The malignant superior cava vein syndrome is a rare clinical entity treated classically with radiation and chemotherapy with a slower response, or surgical bypass, which is an aggressive surgical technique. Endovascular treatment offers a low-invasive technique with quick clinical resolution and good permeability results. However, further studies are lacking to deal with procedure technical characteristics, stent type used, technical complications, and medium- and long-term patency studies. This study aims to evaluate all these items, analysing self-expanding stainless steel and nitinol venous bare metal stents, and add value to endovascular treatment, confirming the good results of this technique.
