Abstract


Objective: The aim of this study is to evaluate the effect of visceral fat thickness on the distance and angle between the superior mesenteric artery (SMA) and the aorta in normal population.

Method: The aortomesenteric distance and  retroperitoneal fat thickness (RFT) were measured on axial plane and  the aortomesenteric angle and  the mesenteric fat thickness (MFT) were measured on sagittal plane using multidetector computed tomography (MDCT). The relationship between MFT, RFT and aortomezenteric angle and distance were evaluated.

Results: There was a weak/ moderate level significant positive correlation between aortomesenteric angle and MFT and RFT (r = 0,396, p<0.001 and r = 0,494, p<0.001 respectively).  There was also a moderate level significant positive correlation between aortomesenteric distance and RFT and MFT (r = 0,607, p<0.001 and r = 0,633, p<0.001 respectively).

Conclusion: The aortomesenteric distance and angle correlate with the retroperitoneal and mesenteric fat thickness. According to this results, retroperitoneal and mesenteric fat thickness might be used as an CT marker to aid in the diagnosis of suspected SMAS in addition to the measurements of the aortomesenteric distance and angle.
