“…Any condition resulting in loss of mesenteric fat pad forming more acute angle (<22°) causes compression of the third part of the duodenum resulting in SMA syndrome [10]. Females, older children, and adolescents are most commonly affected (http//.www.learning radiology.com).…”

Measurement of the Distance and Angle Between the Aorta and Superior Mesenteric Artery on CT Scan: Values in Indian Population in Different BMI Categories

The primary intention of the study was to "prove" that the reduced angle and distance between the superior mesenteric artery (SMA) and aorta significantly correlates with reduced body mass index (BMI). This in turn indicates the strong etiological role of this factor for causation of SMA syndrome. (Most literature till date still mentions sudden depletion of fat pad between the vessels as a "proposed predisposing factor"). The superior mesenteric artery syndrome is characterized by the compression of the third segment of the duodenum by the mesentery at superior mesenteric artery level and a resulting duodenal (±gastric) dilatation. The disease is closely related with the depletion of the fat pad between the vessels narrowing the angle and reducing the distance between the vessels. A prospective study of 100 patients (58 males and 42 females) in the age range 15-85 years (mean age 50 years) who had undergone CT scan for various other complaints. CT scan had been performed with routine protocol comprising plain phase followed by arterial and venous phase by measuring the angle between the aorta and superior mesenteric artery, and also BMI was calculated. Mean values for distance and angle were obtained with standard deviation and 95 % confidence intervals. Pearson coefficients were also calculated and results tabulated. A strong positive correlation exists between BMI and the angle between the aorta and SMA. With increment in BMI, the angle also increases so less chance of developing superior mesenteric artery syndrome.

“…Beyond this bowel segment, the small bowel loops were collapsed. At the level of the third part of the duodenum which lies between the SMA and the aorta, the distance between these two vessels (aorto-mesenteric distance) is 10-28mm [5] . However, aortomesenteric distance in our patient was measured to be only 5 to 6 mm presumably due to depleted periduodenal fat.…”

“…It occurs more commonly in female children and adolescents and in those who have thin body habitus because of paucity of duodenal fat pad [4] . The SMA is normally encased in fatty and lymphatic tissue at its origin which is important for maintaining a wide enough aorto-mesenteric angle and distance, thereby providing protection to the duodenum against compression between the SMA and the aorta [5] . A reduction in the amount of mesenteric or retroperitoneal fat appears contributory to Superior Mesenteric Artery Syndrome.…”

“…The pathophysiological process of this syndrome, resulting in a decrease in aortomesenteric angle, is commonly regarded as being due to a decrease in retroperitoneal fat following acute weight loss (19). There are a number of known aetiologies for SMAS, including malignancies and malabsorption syndromes.…”

Abstract. Superior mesenteric artery syndrome (SMAS)is an uncommon cause of vomiting and weight loss due to compression of the third part of the duodenum by the superior mesenteric artery. Small bowel adenocarcinoma is an uncommon tumor, which is frequently delayed in diagnosis as its symptoms and signs are non-specific. The present study describes a case of SMAS occurring in a 51-year-old man, caused by intestinal obstruction secondary to a primary adenocarcinoma of the duodenal-jejunal junction. To the best of our knowledge, the present case is the first report of small bowel adenocarcinoma masquerading as SMAS. The present case highlights the importance of considering the possibility of SMAS in patients with upper bowel obstruction caused by intestinal
