A bleeding renal artery pseudo-aneurysm complicating renal biopsy. Treatment with transcatheter embolization.

We report the treatment of a bleeding renal artery pseudoaneurysm by transcatheter embolization. The patient, a 30 years old woman, developed macroscopic hematuria following renal biopsy. The presence of a leaking pseudoaneurysm of the lower pole segmental artery was confirmed by left selective renal angiogram; subsequently successful transcatheter embolization was performed using a 5.0 french Cobra catheter and 3 mm steel coils.
