Natural History of Asymptomatic Superior Mesenteric Arterial Stenosis.

Natural History of Asymptomatic Superior Mesenteric Arterial Stenosis Depends on Celiac and Inferior Mesenteric Arteries Status.

The aim of this study was to evaluate asymptomatic superior mesenteric artery (SMA) stenosis prognosis according to the presence of coeliac artery (CA) and/or inferior mesenteric artery (IMA) associated stenosis.

Study Overview
