A 78-year-old man came to our department because of obstructive jaundice, and was diagnosed as pancreatic head cancer. He underwent chemoradiation therapy. A metal stent was inserted into the common bile duct and the patient was followed up on an outpatient basis. The patient visited our emergency department 46 days after stent insertion due to abdominal pain. The patient was diagnosed with ruptured pseudoaneurysm of the superior pancreaticoduodenal artery by angiography and treated with coil embolization. He died due to sudden deterioration the next day. Pathological autopsy revealed that the cause of the ruptured pseudoaneurysm appeared to be vasculopathy due to radiation therapy.
一名78岁男性因梗阻性黄疸前来我院就诊，被诊断为胰头癌。他接受了放化疗。在胆总管内插入了金属支架，并对患者进行门诊随访。支架置入46天后，患者因腹痛前来我院急诊科就诊。通过血管造影诊断为胰十二指肠上动脉假性动脉瘤破裂，并接受了弹簧圈栓塞治疗。次日，患者因病情突然恶化死亡。病理尸检显示，假性动脉瘤破裂的原因似乎是放疗引起的血管病变。
