Background: Cardiovascular disease (CVD) is now a public health problem due to its high prevalence and associated high morbidity and mortality. Measurement of aortic diameters can help in predicting CVD in patients. The objective of this study was to determine the normal value of infrarenal and suprarenal transverse aortic diameter and their relationship on ultrasound among adults in Zaria, Nigeria
Patients and Methods: Three hundred consecutive Nigerian adults without CVD attending ultrasound unit of Radiology Department of Ahmadu Bello University Teaching Hospital, Zaria, were recruited for this study. Routine protocol for scanning the abdomen in the transverse, longitudinal and craniocaudal planes were used to scan the aorta for supra- and infrarenal dimensions.
Results: The mean suprarenal aortic diameter (SAD) of the subjects was 1.79 ± 0.25 cm with a range of 1.15-2.61 cm. The mean infrarenal aortic diameter (IAD) was 1.63 ± 0.23 cm with a range of 1.01-2.46 cm. The mean ratio of infra- and supra-renal diameter was 0.91 (±0.04), in male subjects, it was 0.92 (±0.04) and in female subjects, it was 0.90 (±0.05). IAD, IAD/SAD ratio, and weight were independent predictors of SAD on multilinear regression analysis. SAD, IAD/SAD ratio, age and body mass index were also independent predictors of IAD.
Conclusion: This study has established the normal ratio values of infrarenal to suprarenal transverse aortic diameter in healthy adults and the factors that correlate with transverse aortic diameter, as well as independent predictors of transverse aortic diameter in Zaria. These values would be of help to radiologists, surgeons, and other clinician in the diagnosis, management, and follow-up of cardiovascular patients. |
