胰十二指肠动脉动脉瘤（PDA）罕见，仅占所有内脏动脉动脉瘤的2％，但其半数以上发生破裂而致高死亡率。处理前必须明确真性或假性动脉瘤性质，后者多维发于胰腺炎、腹部外伤或脓毒性栓子，常破人胃肠道。作者分析瑞士日内瓦大学医院1985～1995年所收治的6例穿破性PDA资料，并? Pancreaticoduodenal artery aneurysms (PDA) are rare and account for only 2% of all visceral arterial aneurysms. However, more than half of them rupture and cause high mortality. The nature of the true or pseudoaneurysm must be clearly established prior to treatment, with the latter multidimensional in pancreatitis, abdominal trauma, or septic emboli, often breaking the gastrointestinal tract. The authors analyzed 6 cases of punctured PDA data from the University of Geneva Hospital in Switzerland from 1985 to 1995.
