Characterization of Abdominal Aorta Among Sudanese using Computed Tomography

Abstract

The objective of this prospective study were to evaluate the normal transverse abdominal aorta diameter in normal Sudanese patient using CT scan and correlate the measurements to the mean of patients’ age, body surface area (BSA) and body mass index (BMI). 100 patients without cardiovascular disease with ages ranged between (18 - 20) years were included and patients with cardiovascular problems and congenital aortic anomalies were excluded. Axial CT with contrast image were obtained using CT machine with 120 KVP and 10mAs in the Radiology department (Modern Medical Center and Military Hospital). The measurements of aorta were taken at the levels of T12 to L3 in cms for both ganders. The results showed that the mean transverse diameter of abdominal aorta at levels of T12, L1, L2and L3 in females were (1.89±0.2), (1.69±0.2), (1.5±0.1)and (1.45±0.1) cms and in males were (2.1±0.3), (1.91±0.3), (1.68±0.2)and (1.54±0.2) cms respectively. . Linear relationships between age, BMI and BSA and the Aorta transverse diameter (ATD) were noticed. The transverse measurement for abdominal aorta in Sudanese peoples deferens from other populations.
