Anatomical analysis of the abdominal aorta in a South African sample: influence of age and sex.

Purpose: The anatomy of the abdominal aorta (AA) varies with age and sex; however, limited studies exist from South Africa. Given the increased incidence of endovascular treatment of the AA, reference values are relevant for interventionalists for improving the safety of endovascular procedures. Therefore, the study aimed to determine the lengths, diameters and tortuosity of the AA and their association with age and sex in a South African sample.
