Abstract

Segmental arterial mediolysis (SAM) is a rare, non-inflammatory, vascular condition that predominantly affects medium-sized to large-sized abdominal arteries and can present with haemorrhage into the abdominal cavity. We report the case of a patient with SAM of the coeliac, splenic, renal and gastroduodenal arteries in whom endovascular coil embolisation was successfully used to treat a bleeding gastroduodenal artery pseudoaneurysm.

Keywords: general surgery; interventional radiology; vasculitis.

(A) Catheter angiogram of the gastroduodenal artery via the coeliac axis: proximal and distal pseudoaneurysms of the gastroduodenal artery (smaller proximal pseudoaneurysm marked by white arrowhead; larger distal pseudoaneurysm marked by white arrow). (B) Catheter angiogram post-coil embolisation: no flow into the gastroduodenal pseudoanerysms (site of smaller proximal pseudoaneurysm marked by white arrowhead; site of larger distal pseudoaneurysm outlined by dotted white oval).
