• Abstract Background Understanding the difference of Adamkiewicz artery (AKA) presentation in healthy and diseased subjects, and the influence of atherosclerotic factors prevalent in aortic disease patients, are important for aortic disease therapeutic planning. This study used a 320-detector row computed tomography (CT) device to examine the impact of clinical aspects of AKA identification in individuals with and without aortic disease. Materials and Methods angio-CTs obtained from 115 patients were assessed and the individuals grouped according to the presence or absence of aortic disease. Datasets were analysed using OsiriX software, and AKA was identified by 3D multiplanar reconstruction. Results The group without aortic disease (Group A) comprised 32 (52.5%) males and 29 females, with a mean age of 53.7 ± 16.8 years. The group with aortic disease (Group B) comprised 31 (57.4%) males and 23 females, with a mean age of 64.8 ±11.6 years. AKA was identified in 49 (80.3%) participants of Group A and in 23 (42.6%) of individuals of Group B (p ≤ 0.0001). In 53 cases (73.6%), AKA originated on the left side. AKA was mainly detected on the left side (73.6%), at the level of T10 to T12 (70%). Tobacco smokers, former smokers, and hypertensive patients had increased odds of having undetected AKA. Conclusion: using the method described and a state of the art 320-detector row CT device, AKA was detected more frequently among individuals without aortic disease. Thus, aortic disease and atherosclerotic risk factors hindered AKA detection.
