[Aortic aneurysm and anomalies of the kidney (author's transl)].

Because of the embryological position of the kidney in the small pelvis anomalies of the kidney are mostly localized in the area of the distal aorta. Therefore they can make the resection of an aortic aneurysm more difficult. While anomalies of the renal veins and the urinary tract hardly impair the resection of an aortic aneurysm, an abnormal arterial vascularization of the kidney can be an essential problem during operation. According to criteria concerning localization the arterial anomalies are divided into 4 types. For every type techniques of resection and reconstruction guaranteeing the viability of the abnormal arteries and the kidney are demonstrated.
