Rutin bilgisayarlı tomografi incelemelerinde renal vasküler varyasyonların değerlendirilmesi

Abstract

Aim: Anatomical variations of the kidney, including multiple renal arteries are crucial for renal and abdominal aortic surgery and renovascular hypertension. In this study, we aimed to investigate the frequency of multiple renal arteries in a Turkish population by evaluating the images of patients who underwent contrast-enhanced computed tomography (CT) for various reasons.Material and Methods: Images of patients who underwent contrast abdominal computed tomography in our hospital due to various health problems were evaluated retrospectively. The presence, number, and exit levels of multiple renal arteries were examined.Results: In the study, CT scans of 470 patients, aged between 18 and 69 years (43.7 ± 14.1) were analyzed retrospectively. Of the 940 kidneys evaluated, 113 had multiple renal arteries. Of the multiple renal arteries, 59 belonged to women and 54 to men, and the difference was found to be statistically insignificant. The incidence of multiple renal arteries was determined as 20.6% in evaluated cases and 12% in evaluated kidneys. The number and frequency of occurrence is 53 (47%) in the right kidney and 60 (53%) in the left kidney, respectively, and there is no significant difference between the two sides. Accessory renal arteries originated from the abdominal aorta between lumbar 1 vertebra (L1) and L4, except for 2 cases where they originated from the iliac artery.Conclusion: The incidence of multiple renal arteries in the Turkish population was found at rates similar to the literature, using CT. CT is found to be a reliable method in detecting multiple renal arteries. Considering the presence of multiple renal arteries in CT examinations, we think that valuable information can be obtained in the investigation of renovascular hypertension.
