Assessment of Normal Diameter of Thoracic Aorta Using Computed Tomography Angiography

ObjectiveThis retrospectiv study aimed to asses normal diameter of the thoracic aorta in the healthy Sudanese population using Computed Tomography AngiographyMaterial and MethodAtotal of 50 chest were retrospective investigated in the period spanning from March 2021to May 2021. (160 – 16)slice CT units (Toshiba aquilion Medical Systems) were used to examine patients at two hospitals in Khartoum State, Sudan. The diameters of the thoracic aorta were calculated manually at five points by using the standard clinical MethodThe average thoracic aorta diameters of the all population at five points Sino tubular Junction, Mid-Ascending Aorta, Transverse aorta, Mid Descending aorta, and Diaphragmatic Hiatus.Resultwere Sino tubular Junction sagittal was 1.80 to 5.50Sino tubular Junction axial was1.41 to 4.44 Mid-Ascending Aorta sagittal was 2.20 to 3.90 Mid-Ascending Aorta axial was 2.02 to 3.88 Transverse aorta sagittal was 2.00 to2.90 Transverse aorta axial was2.03 to 3.72 Mid-Descending aorta sagittal was 1.23 to 3.11 Mid-Descending aorta axial was 1.20 to 3.50 Diaphragmatic Hiatus sagittalwas 1.34 to 3.50 Diaphragmatic Hiatus axial was1.07to2.99respectively.Conclusionthat These results provide normative data for evaluating a patient’s thoracic aorta enlargement. Furthermore, computed tomography is playing a great role in the measurement of the diameter of the thoracic aorta.
