“…This is in concordance with the findings of the study performed by Ozkurt et al [3] who concluded that the aortomesenteric angle and distance significantly correlate with BMI in normal population. Additionally, we also observe strong positive correlation between angle and distance.…”

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.

The nutcracker phenomenon [left renal vein (LRV) entrapment syndrome] refers to compression of the LRV most commonly between abdominal aorta and superior mesenteric artery. Term of nutcracker syndrome (NCS) is used for patients with clinical symptoms associated with nutcracker anatomy. LRV entrapment divided into 2 types: anterior and posterior. Posterior and right-sided NCSs are rare conditions. The symptoms vary from asymptomatic hematuria to severe pelvic congestion. Symptoms include hematuria, orthostatic proteinuria, flank pain, abdominal pain, varicocele, dyspareunia, dysmenorrhea, fatigue and orthostatic intolerance. Existence of the clinical features constitutes a basis for the diagnosis. Several imaging methods such as Doppler ultrasonography, computed tomography angiography, magnetic resonance angiography and retrograde venography are used to diagnose NCS. The management of NCS depends upon the clinical presentation and the severity of the LRV hypertension. The treatment options are ranged from surveillance to nephrectomy. Treatment decision should be based on the severity of symptoms and their expected reversibility with regard to patient's age and the stage of the syndrome.

“…The study patient was thin and her abdominal pain was exaggerated by physical activities. Regarding anatomy, when the body is upstanding, visceral proptosis diminishes the angle between the SMA and aorta, heightens the hemodynamic response especially if there is decreased retroperitoneal and mesenteric fat tissue (10).…”

Introduction: Renal vein entrapment, named nutcracker phenomenon, is a contraction of renal vein between abdominal aorta and superior mesenteric artery. Patients can be asymptomatic or clinically manifested, called nutcracker syndrome. Proteinuria, hematuria, flank pain, varicocele in males and pelvic congestion in females are reported in such patients. Case Presentation: The current report presented an eight-year-old girl with microscopic hematuria and chronic abdominal pain along with short review of anatomy, pathophysiology, clinical significance and management of this syndrome. Conclusions:The nutcracker syndrome should be differentiated from unexplained chronic abdominal pain.

Measurement of the distance and angle between the aorta and superior mesenteric artery: normal values in different BMI categories

Abstract: The aortomesenteric angle and distance significantly correlate with BMI in normal population. The mean values, we report, may be used as normal values to help reach the diagnosis of superior mesenteric artery syndrome.
