Vein graft stenosis is a well-recognized complication of infrainguinal bypass surgery. Balloon angioplasty is an accepted method for managing vein graft stenosis in selected patients. This intervention is not without complication. We present 2 cases of delayed pseudoaneurysm formation after balloon angioplasty of vein graft stenoses. Both cases showed a persistent contrast stain or blush as an indication of vein wall damage and propose that this is a radiological harbinger of delayed rupture and pseudoaneurysm formation.
静脉移植物狭窄是股动脉以下旁路手术中一种公认的并发症。球囊血管成形术是治疗特定患者静脉移植物狭窄的一种公认方法。这种干预并非没有并发症。我们报告2例静脉移植物狭窄球囊血管成形术后延迟性假性动脉瘤形成的病例。两例均显示持续的造影剂染色或造影剂外溢，提示静脉壁损伤，并提出这是延迟破裂和假性动脉瘤形成的影像学先兆。
