Successful endovascular treatment of multiple mesenteric arterial aneurysms associated with alpha-1-antitrypsin deficiency

We present a rare case of a patient who presented with acute abdominal pain with a previous history of alpha-1-antitrypsin deficiency (α1-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 α-1-antitrypsin deficiency is explored.
