[The rupture of an abdominal aortic aneurysm in a patient with a fused horseshoe kidney. A clinical case report].

An emergency operation for a ruptured aortic aneurysm can be very difficult in the presence of horseshoe kidney. This concomitance is rare but represents an interesting challenge for vascular surgeons. The authors report a case of 80 year old male patient who reached the operating theatre for ruptured aortic aneurysm. Unexpectedly a preaortic horseshoe kidney was found. The authors describe the surgical technique adopted to get rapidly to the aneurysm collar preserving kidney integrity.
