Measurement of Normal Diameter of Thoracic Aorta using Computed Tomography

Abstract

This is a cross sectional descriptive study, deals with measurement of normal diameter of the thoracic aorta in Sudanese population. The study conducted at computed tomography departments of Alribat National hospital , Alamal National hospital diagnostic center and Doctor’s spthalized hospital. A 50 cases were selected randomly, The patients are not suffering from any pathological condition concerning the thoracic aorta. This study used the tools of computed tomography to measure the normal diameter of the descending thoracic aorta. The data designed to include the specific variables for the patients and were analyzed by SPSS program. The mean Length of the thoracic Aorta was 14.71±2.67 cm, The Proximal width of Aorta was 2.51±0.56 cm, the middle width of Aorta was 2.08±0.41 cm, the distal width of Aorta was 2.11±0.45 cm. The height and weight of the patient has showed no significant difference with the aorta diameter than the other variable (p-value is 0.000) respectively. Also highly significant difference (P=0.001) was detected between age and distal width of aorta, but low significant difference (P=0.018) was obtained between the height of the patient and distal width of Aorta. Also lower significant difference (P=0.015) was noticed between weight of the patient and distal width of Aorta. the study concluded that computed tomography is play a great role in the measurement of normal diameter of descending of thoracic aorta
