Prevalence of Accessory Renal Artery in Aortic Aneurysms

Abstract

INTRODUCTION: Open surgical procedures and endovascular aortic procedures are the most feared renal injuries in abdominal aortic surgery. The presence of renal anomalies and clear localization during aneurysm repair brings surgical success. In this article, we aimed to show the importance of renal anomalies in terms of mortality and morbidity in aneurysm repair. METHODS: Between January 2017 and January 2019, 250 patients with aortic aneurysm and CT angiography were included in the study. The files of the patients who underwent computerized contrast angiography for aortic aneurysm in ALKU Alanya Training and Research Hospital were reviewed retrospectively. RESULTS: Bilateral renal artery was detected in four male patients; and left accessory renal artery was detected in five male and three female patients. At the end of the study, 250 patients were screened; and bilateral renal arteries were detected in 1.6%, left accessory arteries were detected in 3.2% of the eight patients. DISCUSSION AND CONCLUSION: It is important that surgeons and radiologists know the accessory arterial variations not only in abdominal aortic surgery, but also in recent years due to increased renal transplantation reconstruction, urological and radiological surgical techniques.
