Establishing Reference Diameters of Abdominal Aortic and Inferior Vena Cava of Sudanese Using Computed Tomography

Abstract

Computerized angiography (CTA) is a standard tool for investigating vascular diseases .The aims of this study were to study Reference Diameters of Abdominal Aortic and Inferior Vena Cava of Sudanese Using Computed Tomography and to study the variation in aortic diameters with age and gender. A total of 200 patients (108 males and 92 females) with a mean age of 48.6 years consecutive adults free of cardiac or aortic structural disease or arrhythmia who referred for abdominal CT scanning in the radiology department of Royal Care Hospital in Khartoum- Sudan during the period from August 2015 to May 2018. This study revealed that the mean internal diameters of the suprarenal and infrarenal abdominal aorta were measured at T12 and L3 vertebral levels and tabulated according to various age groups for both men and women. The results revealed that the mean diameter of the suprarenal abdominal aorta, measured at T12 vertebral level was19.44 mm in women and 20.97mm in men. The mean diameters of the infrarenal abdominal aorta, measured at L3 vertebral level were 14.13 mm. in women and 17.34 mm. in men. The mean± standard deviation (SD) of the anteroposterior (AP) diameter of the IVC in men measured was 25.471.69 mm, 24.151.58 in women . The mean± standard deviation (SD) of the transverse (TV) diameters, measured were 14.111.46 mm. in women and 15.31121.49919mm in men. It concluded that normal dimensions abdominal aorta by CT scan was established and correlated with age and gender which is similar to previously published studies, that normal dimensions IVC by CT scan was established and correlated with age and gender, The information provided in this study will allow radiologists to detect and accurately characterize IVC abnormalities to guide clinical decision making and improve patient care. Recognition of IVC processes is essential to pa¬tient treatment.
