OBJECTIVE OF THE STUDY: To determine the relevance of the transverse aortic arch diameter in the evaluation of early aortic and cardiac enlargements.
SUBJECT AND METHOD: A total of 1818 chest radiographs of male and female normotensive and hypertensive Nigerians of age range 4-80 and 10-80 years respectively were used for this study. Ages of subjects were obtained and transverse aortic arch, chest and heart diameters were determined.
RESULTS: Mean aortic arch diameter for the normotensive groups were noted to be 5.0 +/- 0.5cm, 4.5 +/- 0.4cm and 4.7 +/- 0.5cm for males, females and both sexes respectively while 5.9 +/- 0.9cm, 5.4 +/- 0.6cm and 5.6 +/- 0.8cm for males, females and both sexes respectively were noted in the hypertensive group. Mean values were also generated for the chest and heart diameters. The study reports a mean difference in the aortic arch, heart and cardiothoracic ratio of 15% between the two groups.
CONCLUSION: Relationship between aortic arch and heart diameter was established and aortic arch diameter was noted to be significant (p< 0.05) in evaluating aortic and cardiac enlargements.
