Stent occlusion after stenting for chronic iliofemoral venous disease has an incidence of around 3% to 12% in the literature. The reasons for such occlusion vary, with patient and stent-related factors playing a role. One stent-related issue leading to stent occlusion is the use of undersized stents. Although undersized nitinol stents can be fractured and relined, this is not an option with a woven stent (eg, Wallstent). With an undersized, occluded woven stent, an option would be to bypass the occluded stent. This case report outlines the author's experience in such a setting where a patient presented with an undersized, occluded iliofemoral venous stent with severe quality-of-life impairing symptoms, and an endovenous bypass was created around the occluded stent column using Wallstent-Z stent combination. Nine months on, the patient remains significantly better with a patent stent.
在慢性髂股静脉疾病支架置入术后，支架闭塞在文献中的发生率约为3%至12%。这种闭塞的原因各不相同，患者因素和支架相关因素都起作用。导致支架闭塞的一个支架相关问题是使用尺寸过小的支架。尽管尺寸过小的镍钛诺支架可能会断裂并重新内衬，但对于编织支架（如Wallstent）来说这不是一个选择。对于尺寸过小且闭塞的编织支架，一种选择是绕过闭塞的支架。本病例报告概述了作者在这样一种情况下的经验，即一名患者出现尺寸过小且闭塞的髂股静脉支架，并伴有严重影响生活质量的症状，通过使用Wallstent-Z支架组合在闭塞的支架柱周围创建了静脉旁路。九个月后，患者情况显著改善，支架保持通畅。
