Abstract    Postoperative pseudoaneurysm rupture is a major cause of delayed massive haemorrhage after surgical，interventional or endoscopic treatment in biliary and pancreatic patients，which is difficult to treat and carries a high risk of death. The causes of postoperative pseudoaneurysm in biliary and pancreatic diseases are complex and varied，and the clinical symptoms are insidious before the pseudoaneurysm ruptures and bleeds. Prevention the pseudoaneurysm formation from the source of pathogenic mechanism and paying attention to the characteristic clinical symptoms such as sentinel bleeding will effectively ensure the perioperative safety of biliary and pancreatic patients and improve the success rate of postoperative delayed massive haemorrhage.

Key words: biliary tract, pancreas, delayed massive haemorrhage, pseudoaneurysm, sentinel bleeding

摘要： 胆胰疾病病人经外科手术、介入或内镜治疗后发生迟发性大出血时，救治困难、病死率高，而术后假性动脉瘤形成和破裂是主要原因。胆胰手术后假性动脉瘤成因复杂多样，瘤体破裂出血前临床症状隐匿。从致病机制源头预防假性动脉瘤形成、重视前哨出血等特征性临床症状，将会有效确保胆胰疾病病人围手术期安全性，提高术后迟发性大出血的救治成功率。
