Arteria Renalis Varyasyonları: Bir Multidetektör BT Anjiyografi ÇalışmasıSerkan Öner1, Zulal Öner21Karabük Üniversitesi Tıp Fakültesi, Radyoloji Anabilim Dalı, Karabük, Türkiye2Karabük Üniversitesi Tıp Fakültesi, Anatomi Anabilim Dalı, Karabük, Türkiye Amaç: Aorta abdominalis’in bir çift dalı olan arteria renalis (AR)’in varyasyonları oldukça sık görülmektedir. Literatürde farklı popülasyonlarda kadavra çalışmaları ve görüntüleme yöntemleri ile bu varyasyonlar gösterilmiştir. Bu çalışmanın amacı MD-BTA ile AR çaplarını, sayılarını, orjin seviyelerini ve dallanmalarını değerlendirmek ve saptanan varyasyonların literatürde yer alan sonuçlarla karşılaştırmasını yapmaktır. Variations of Arteria Renalis: A Study of Multidedector CT AngiographySerkan Öner1, Zulal Öner21Karabük University Faculty of Medicine, Department of Radiology, Karabük, Turkey2Karabük University Faculty of Medicine, Department of Anatomy, Karabük, Turkey Aim: Variations of renal artery (RA), a pair of branches of the abdominal aorta, are very common. In the literature, these variations are shown by cadaveric and imaging methods in different populations. This study aimed to evaluate the diameters, numbers, origins, and branchings of RA by the Multi-detector (MD) Computerized Tomography Angiography (CTA), and to compare the results of the determined variations with those in the literature. Material and Method: The study included 206 patients aged 18– 85 years with CTA images. An experienced radiologist analyzed all images in two and three-dimensional reconstructions. The diameters, numbers, branchings and origin levels of RA were evaluated. Results: In a total of 206 patients, 50% RA variation was detected including 71 multiple RA and 32 early branching. The prevalence of multiple RA and early branching in men was 39.7% and 34.9%, respectively. RA anomalies were observed 26% and 18.8%, respectively in women. The most observed variation was the presence of an accessory RA in the right or left kidney (23.5%). The mean RA diameters are 5.17 mm (1.8–7.9 mm) for the right RA and 5.13 mm (1.5–9.1 mm) for left RA. All RA origin levels are between the T12 vertebral corpus and the L4–5 intervertebral disc distance. L1 vertebral corpus (46%) was the most common level. Conclusion: As a result, 50% variation is observed in RA according to the typical pattern. Knowledge of these variations is essential in kidney transplantation. CTA is a beneficial and effective method for demonstrating these variations. Keywords: arteria renalis, multiple arteria renalis; MD-CTA; variationSerkan Öner, Zulal Öner.
