Measurement of Superior Mesenteric Artery using Computed Tomography Angiography

Abstract

A number of diseases are accompanied by the altered size of various abdominal vassals, including aneurysms, atherosclerosis, and infection conditions. Computed tomography (CT) has played an important role in helping physicians and surgeons for taking normal anatomical measurements and establishing a diagnosis. The present study attempts to measure the normal superior mesenteric artery (SMA) for the healthy Sudanese population using computed tomography angiography. A total of 113 CT abdominal angiography cases were retrospectively investigated in spinning from February 2020 to May 2021. Both 32-slice CT units (Siemens Medical Systems) were used to examine patients at two hospitals in Khartoum, Sudan. All measurements were calculated manually using the standard clinical method. The study shows that SMA length and diameter were 101.1±24.6 mm and 5.274±1.5 mm, retrospectively. The distance between the celiac trunk and SMA was 4.6±1.4 mm. Furthermore, the angle between the abdominal aorta and SMA was 66.1±29.5 mm. In conclusion, this study had established baseline measurements for SMA for the healthy Sudanese population. Furthermore, it found that CTA of abdomin is the best for investigation of the SMA and can provide a guide for the clinicians to manage SMA abnormalities.
