Aorto-iliac aneurysm associated with congenital pelvic kidney: A short series of successful open repairs under hypothermic selective renal perfusion

The occurrence of congenital pelvic kidney (cPK) during aorto-iliac aneurysm repair is an extremely unusual finding. We report a series of four patients with aorto-iliac aneurysm and associated cPK who underwent aorto-iliac repair at our institution over the last 10 years. Aorto-iliac aneurysm repair under cPK selective hypothermic perfusion was successfully accomplished in all cases. All the cPK arteries were spared and were selectively reimplanted when required. No major complications or death were reported at long-term follow-up. Open surgical repair of aorto-iliac aneurysm in patients with cPK is safe and effective and, in our short series, we observed no worsening of the renal function; besides, we reported a persistent improvement of the renal function in two out of the four cases.
