Key result
Endovascular aneurysm repair successfully relieved duodenal obstruction in a patient with aortoduodenal syndrome, without requiring aneurysmal sac shrinkage.
Why the study?
The mechanism of duodenal blockage in aortoduodenal syndrome remains unclear, and reports of endovascular aneurysm repair (EVAR) for this condition are rare.

EVAR may be a feasible, less invasive treatment option for aortoduodenal syndrome that can relieve duodenal obstruction without requiring open aneurysmal sac resection.
EVAR may relieve obstruction in aortoduodenal syndrome without sac shrinkage; hypothesis-generating pending prospective data.
Aortoduodenal syndrome is a rare duodenal obstruction caused by an abdominal aortic aneurysm. Current treatment involves open aneurysmal repair according to the theory that this procedure releases the duodenum from mechanical compression. However, the mechanism of duodenal blockage remains unclear and reports of endovascular aneurysm repair (EVAR) for aortoduodenal syndrome are quite rare. We report our successful case of EVAR for aortoduodenal syndrome without aneurysmal shrinkage and discuss the mechanism of duodenal obstruction.

Kawaguchi et al. (2020) conducted a case report in Aortoduodenal syndrome (n=1). Endovascular aneurysm repair (EVAR) was evaluated on Relief of duodenal obstruction. Endovascular aneurysm repair successfully relieved duodenal obstruction in a patient with aortoduodenal syndrome, without requiring aneurysmal sac shrinkage.
