Superior Mesenteric Artery Syndrome After Successful Coil Embolization of a Ruptured Pancreaticoduodenal Artery Aneurysm: Report of a Case

Superior mesenteric artery (SMA) syndrome is a rare condition in which the third part of the duodenum is trapped between the abdominal aorta and the SMA. Any disease process decreasing the angle between the aorta and the SMA can result in external compression of the duodenum and subsequent intestinal obstruction. Aneurysms of the pancreaticoduodenal artery (PDA) and its branches are also rare and account for only 2% of all splanchnic artery aneurysms. We report a case of SMA syndrome that developed after successful coil embolization of a ruptured PDA aneurysm.
