    Abstract:
    Renal artery aneurysms (RAAs) are an uncommon finding but are more often associated with other congenital disorders. The complex (hilar) RAAs constitute a subset of RAAs that present a therapeutic dilemma for the vascular surgeon because of their anatomic location. This dilemma worsens when hilar RAAs occur with a solitary kidney where organ preservation is vital. Ex vivo reconstruction with autotransplantation is especially suitable for hilar RAAs, even when they are associated with a solitary kidney. We report 2 of such cases of RAAs with a solitary kidney in patients with pertinent congenital anomalies. In 1 case, the hilar RAA was associated with a significant accessory renal artery, whereas in the other case, the hilar RAA was associated with a significant connective tissue disorder. Ex vivo reconstruction and autotransplantation was successful in both cases; however, treatment modalities had to be adapted to the patient's unique conditions.
