Purpose: With the advances in the new image techniques and 3D modeling, angiography computed tomography (A-CT) has become
a very useful image for studying vessels. Renal artery (RA) variations are common and have a clinical relevance in pre-operative
planning. There are several descriptive studies made in high income countries, but there are not many in middle and low income
countries. Our objective was to describe prevalence of RA variations in a study population in Cali, Colombia.
Methods: A database was made from a selection of A-CT 3D images from January 1, 2012 to September 30, 2014, from which
the RA could be visualized. Patients below 18 years of age were excluded, also with no 3D A-CT, or not of Colombian nationality.
Frequencies, percentages were calculated using Microsoft Excel.
Results: A total of 560 patients were selected, of which 296 fulfilled all criteria. The most common causes of performing the A-CT
were pathologies of the Aorta. Variations of the RA were present in 52% of the patients, 54% were man, 77% had unilateral variation
and 33% had bilateral variations, 58% in the right side. The two most common variations were extra Renal arteries (hiliar and polar)
seen in 70% of the patients.
