We present a rare case of a patient who presented with acute abdominal pain with a previous history of alpha-1-antitrypsin deficiency (alpha1-antitrypsin deficiency). Further clinical deterioration necessitated computed tomography (CT) imaging, which demonstrated a hemoperitoneum. Angiography confirmed the rupture of multiple aneurysms originating from the mesenteric arterial arcade, which were treated successfully with endovascular embolization. The association between mesenteric arterial aneurysm rupture and alpha-1-antitrypsin deficiency is explored.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
