To describe a case of extrinsic compression of the Ovation stent-graft following glue embolization for type II endoleak.
A 75-year-old man with a past history of ischemic heart disease and endovascular aneurysm repair with an Ovation stent-graft was admitted for treatment of type II endoleaks from the right L2 and left L4 lumbar arteries with egress via the inferior mesenteric and right L4 lumbar arteries, respectively. Successful embolization was performed via a translumbar sac puncture with a combination of coils and histoacryl glue. On final angiography severe lumen narrowing of the unsupported portion of the Ovation stent-graft was seen owing to extrinsic compression by the glue. This was successfully salvaged with percutaneous transarterial kissing balloon angioplasty.
Aortic lumen narrowing caused by extrinsic compression of an Ovation stent-graft following glue embolization of type II endoleak is an unusual and potentially problematic complication.
描述一例 Ovation 支架移植物在胶栓塞治疗 II 型内漏后发生外部压迫的病例。
一名 75 岁男性，既往有缺血性心脏病病史和 Ovation 支架移植物血管内修复史，因 II 型内漏分别从右 L2 和左 L4 腰椎动脉进入，通过肠系膜下动脉和右 L4 腰椎动脉流出。通过经腰囊穿刺，使用线圈和Histoacryl 胶成功进行了栓塞治疗。最后行血管造影显示，由于胶的外部压迫，Ovation 支架移植物无支撑部分的管腔明显变窄。经皮经动脉吻合并球囊血管成形术成功挽救了这一情况。
Ovation 支架移植物在胶栓塞治疗 II 型内漏后发生外部压迫导致主动脉管腔变窄是一种不常见且可能有问题的并发症。
