假性動脈瘤破裂引起腸胃道出血是少見，卻是致命的胰臟炎併發症。在治療上，即使是病情危及的病人，血管攝影加上動脈栓塞仍是最安全、且最有效的治療方法。我們報告一個經由動脈栓塞，成功治療的假性動脈瘤破裂引起大量吐血的病例，並討論胰臟炎引起之假性動脈瘤的機轉、診斷及治療。
Ruptured pseudoaneurysm with gastrointestinal bleeding is a rare but frequently fatal complication in patients with pancreatitis. Arteriographic embolization of visceral artery pseudoaneurysms is a safe and highly effective technique for the identification and treatment of hemorrhage even in critically ill patients. We report a case of massive hematemesis caused by rupture of a pseudoaneurysm successfully treated by transcatheter embolization.
