医原性肝动脉假性动脉瘤的血管造影诊断与栓塞治疗（附24例报告）

Angiographic Diagnosis and Embolization Therapy of Latrogenic Hepatic Artery Pseudoaneurysm:A Report of 24 Cases

笔者报告了经选择性肝动脉造影证实的２４例医原性肝动脉假性动脉瘤，３例源于胆囊切除术后并破裂与胆道相通发生消化道大出血，其余２１例发生于经导管肝动脉灌注化疗与栓塞术后，由血管内膜损伤引起。所有病例均施行了肝动脉栓塞治疗并取得良好治疗结果。笔者描述了肝动脉假性动脉瘤的血管造影表现并讨论了诊断与治疗问题。

Twenty four patients with iatrogenic hepatic artery pseudoaneurysm demonatrated by selective hepat ic arteriography were reported.In 3 patients,the pseudaaneurysms occurred after cholecystectomy and ruptured into biliary duct with massive gastrointestinal hemorrhage.In the remain-ing 21 patients the pseudoaneurysms were caused by intimal injury following transcatheter hepatic artery infusion and embolization. Hepatic artery embolization therapy was performed for management in all 24 patients with good therapeutic result.The angiographic manifestations of hepatic artery pseudoa-neurysm were described and the problems of the diagnosis and treatment were discussed.
