내시경역행담췌관조영술 후 발생한 복강 가성동맥류 파열

A visceral artery pseudoaneurysm after ERCP is a rare adverse event that is potentially life-threatening. Most cases reported pre­viously originated from the peripancreatic arteries, including the splenic artery, gastroduodenal artery, or pancreaticoduodenal artery. The mechanism of the occurrence of visceral artery pseudoaneurysms after ERCP has not been elucidated until now. Recently, a pseudoaneurysm rupture originating from the superior mesenteric artery after ERCP was observed in a patient with­out a history of pancreatitis. This paper reports this case with a review of the relevant literature.
