Surgical therapy of aorto-iliac aneurysm in a patient with congenital solitary pelvic kidney (CSPK): case report and literature review

We report a case of a man with an Aorto-Iliac aneurysm and a congenital solitary pelvic kidney (CSPK). The maximum diameter of the aneurysm was 58 mm and the pelvic kidney was perfused by a single renal artery originating from the aortic bifurcation. A computed tomography scan was used for pre-operative planning and the patient underwent aorto-iliac aneurysm replacement with a Dacron graft. The renal artery was reimplanted on the Dacron right limb with a ‘Carrel patch’. Several strategies were adopted to prevent renal ischemia such as sequential aortic cross clamping, selective cold perfusion of renal artery and a temporary Pruitt–Inahara shunt. The post-operative course was characterized by a transient increase in serum creatinine that did not require treatments and the patient was discharged after seven days. Congenital anomalies such as CSPK represent a challenge for the surgeon; however, the adoption of different intraoperative available strategies allowed to reduce possible complications.
