Measurement Of The Thoracic Aorta In Sudanese People By Using Computed Tomography

Abstract

Correctly defining aortic dilatation requires upper limits of normal for aortic diameters. This study measured normal thoracic aorta diameter in adult Sudanese using computed tomography. Computerize tomography studies for patientswere performed in Royal scan for medical services and Alyaa specialize hospital in Khartoum Sudan during the period from December 2019 to September 2020.The data were collected from 50 normal subjects. The patient's age, gender, height, weight, ascending aorta diameter, and descending aorta diameter were recorded. The measurements were taken from the axial slice at the level of pulmonary bifurcations at reproducible anatomic landmarks perpendicular to axis of blood flow. Data was analyzed as mean and standard deviation (SD) for all of the variables. The correlations were significant at P < 0.05. Out of 50 participants, 20(40%) were men and 30(60%) were women. The mean age was 53.68±19years. The mean diameter of the ascending aorta in men was 3.5±.6 cm, compared with 2.9±.2cm in female. The mean diameter of the descending aorta in male was 2.5±.3cm, compared with 2.4±.2cm in the female The study revealed that the aortic diameters foradult Sudanese were 3.2 ± 0.5 cm for the ascending aorta and 2.4 ± 0.2 cm for the descending thoracic aorta. The study found thatthe aortic diameters in a male are larger than a female.The study showed that is a positivelinear relationship between aortic diameters and age, while a negative linearrelationbetweenthe thoracic aorta and BMI was found in this study. In conclusion, Age, BMI as well as gender need to be taken into account when assessing an individual patient.
