Abstract

Transcatheter sinus venosus defect (SVD) closure with covered stents is emerging as an alternative to surgery. An adequate anchor zone in the superior vena cava is mandatory for the stability of the covered stent to prevent caudal embolization. There is a potential risk of innominate vein occlusion by the fabric of the covered stent in patients with a very short superior caval vein. Three among a total of 105 patients who underwent SVD closure at our institution developed innominate vein occlusion. Predisposing anatomical factors, identification and management of occluded innominate vein, and follow-up outcomes are discussed.

摘要

带覆膜支架的经导管静脉窦缺损（SVD）闭合术正在成为外科手术的替代方法。为了使覆膜支架稳定，必须在上腔静脉中有足够的锚固区，以防止尾栓塞。对于上腔静脉非常短的患者，覆膜支架的织物存在无名静脉闭塞的潜在风险。在我们机构接受SVD关闭的105例患者中有3例出现无名静脉阻塞。诱发解剖学因素，闭塞无名静脉的识别和管理，并讨论了后续结果。
