Superior mesenteric artery
syndrome (SMAS), which is also known as Wilkie's syndrome because it was described by Wilkie as chronic duodenal ileus in 1927 for the first time, is a life-threatening clinical picture that develops as a result of obstruction of the second or third part of the duodenum compressed between the aorta and superior mesenteric artery
CT angiogram revealed reduction of aortomesenteric angle and aortomesenteric distance which were both consistent with superior mesenteric artery
Multiple studies have also demonstrated the value of certain imaging findings, including pneumatosis intestinalis (Figure 1), isolated SMA occlusion, as well as celiac and inferior mesenteric artery
occlusion with distal SMA disease (branch vessel occlusions or narrowing), arterial embolism, or venous gas (Figure 2).
The superior mesenteric artery
(SMA) syndrome is a rare entity, usually presenting with acute or chronic upper gastrointestinal tract obstruction and weight loss, due to the compression of the third part of the duodenum between the abdominal aorta and the SMA itself .
