Vascular pseudoaneurysms are a rare yet life-threatening complication of untreated pancreatic pseudocysts related to their high risk of rupture and bleeding. Several studies and reports have established endovascular approaches as a successful first-line therapy in the management of arterial pancreatic pseudoaneurysms. However, no reports have been published describing endovascular repair of a venous pseudoaneurysm that developed after infection of a chronically stable pancreatic pseudocyst, most likely due to its rare occurrence. We report in this technical note the treatment of a superior mesenteric vein pseudoaneurysm that developed as a result of an infected small pancreatic pseudocyst, by radiologic placement of a covered endovascular stent.
血管假性动脉瘤是未经治疗的胰腺假性囊肿的一种罕见但危及生命的并发症，与它们高破裂和出血风险有关。一些研究和报告已经确定了血管内方法作为治疗动脉性胰腺假性动脉瘤的一种成功的一线治疗方法。然而，尚未有报道描述在慢性稳定的胰腺假性囊肿感染后发生的静脉假性动脉瘤的血管内修复，这很可能是由于其罕见发生。我们在此技术说明中报告了一例肠系膜上静脉假性动脉瘤的治疗，该假性动脉瘤是由感染的小胰腺假性囊肿引起的，通过放射学放置覆膜血管内支架来治疗。
