title: Hypovolemic shock caused by a true aneurysm of the pancreatico-duodenal artery: case report and review of the literature.
abstract: True pancreatico-duodenal artery aneurysm (PDAA) is a rare condition that since 1973 has been described in only 54 cases. It is frequently associated with celiac axis stenosis and often present with rupture. Even if most PDAAs that are not ruptured are asymptomatic and are diagnosed during investigation for other diseases, they may have some symptoms, such as chronic abdominal discomfort and an abdominal pulsating mass, that can be helpful for diagnosis. The treatment of this condition has evolved in time from a merely surgical one to an angiographic noninvasive approach. We present a case of a PDAA that manifested with sudden hypovolemic shock requiring an emergency operation, and through a review of the literature, we discuss the different diagnostic/therapeutic protocols to use in different situations.
