Abstract：
Cystic artery stump pseudoaneurysm (CASP) is a potentially life-threatening condition that can be related to multiple etiologies, especially the iatrogenic factor owing to the increased number of hepatobiliary procedures. Most patients present with haemobilia. Here we report a successfully managed case of CASP that initially complained of right upper abdominal pain. A 38-year-old patient developed bile duct injury after laparoscopic cholecystectomy (LC) which was identified by magnetic resonance cholangiopancreatography (MRCP). Later, she developed haemobilia due to CASP which was then treated by trans-arterial embolization (TAE). CASP is a rare complication of post-LC, yet potentially life-threatening, with possible delayed complications occurring months to years after the surgery. Clinicians and radiologists should be aware of this important entity and its variable manifestations to facilitate early treatment.
摘要：
囊性动脉残端假性动脉瘤（CASP）是一种可能危及生命的疾病，可能与多种病因有关。尤其是由于肝胆手术数量增加导致的医源性因素。大多数患者表现为胆道出血。在这里，我们报告了成功管理的CASP病例，该病例最初抱怨右上腹痛。一名38岁的患者在腹腔镜胆囊切除术（LC）后出现胆管损伤，并通过磁共振胰胆管造影（MRCP）鉴定。稍后，她由于CASP而出现胆道出血，然后通过经动脉栓塞（TAE）治疗。CASP是LC后的罕见并发症，但可能危及生命，术后数月至数年可能出现延迟并发症。临床医生和放射科医生应该意识到这一重要实体及其可变表现，以促进早期治疗。
