Fast-growing traumatic renal false aneurysm treated by percutaneous embolization.

Renal artery false aneurysms are rare after blunt abdominal trauma, however, its rupture can be fatal. We report the case of 34 years old patient who suffered blunt trauma in a traffic accident, CT scan revealing three false aneurysms and splenic arteriovenous fistula classified as AAST 3 treated by coil embolization and a 9 mm left renal artery false aneurysm. Control CT scan five days later showed an increase in renal artery false aneurysm size to 17 mm. To prevent rupture, trans-arterial embolization was indicated. Arteriography revealed an aneurysmal sac arising on the face of a truncal branch which embolization would cause infarction of an entire segment. We therefore performed selective percutaneous embolization under ultrasound guidance using the glue in order to maximum nephron preservation. The technique was satisfactory, with no immediate complications. End arteriography showed exclusion of aneurysmal sac and satisfactory enhancement of entire renal parenchyma.
