Abstract
BACKGROUND: For decades, the arch of aorta has been an area of interest for many cardiothoracic surgeons, researchers in radiology and researchers in anatomical sciences. The increasing rate of pathologies and surgical complications involving the cardiovascular system has served to propel further research in developmental and adult anatomical features of the arch of aorta.
The present study, set out to determine the anatomical variation in the dimension and prediction of aortic arch dimensions in some States in South-South Nigeria using computed tomography scan. Two hundred (200) retrospective tomographs from Computed tomography (CT) scans were used for data collection and the tomographs met all the inclusion criteria.
108 were males while 92 were females. With the use of DICOM software, images were reviewed accordingly and the branching patterns as well as positions were noted. The ages ranged from 26 to 72years, with a mean age of 51.21 years, SEM of 0.85 and SD of 12.02. From the 200 subjects, the aortic length of age group 25-34years for females was 37.43±0.62, while males 39.91±0.00 at P65 years shows significant difference between both sexes and females in this age group is the least having just six (6).
From the study, it has been unearthed that the aortic arch dimension increases with increase in age and males have higher values than females. Also, the aortic arch diameter and length can be predicted from the observed values for both males and females.
