| Abstract |
|
The use of superselective embolization was assessed as a treatment for bleeding from arteriovenous fistulas and pseudoaneurysm after renal biopsy procedure. But unless it is sufficiently selective, the procedure results in loss of significant amount of renal parenchyme. We experienced one case of renal arterial pseudoaneurysm, which happened at 5days after percutaneous renal biopsy. Diagnosis of pseudoaneurysm was made by ultrasound examination with Doppler flow and was confirmed with arteriography.
The rupture of pseudoaneurysm was occluded by transcatheter embolization with placement of a steel coli and polyvinlyl alcohol from the renal arterial approach.
This procedure was allowed non surgical closure of the AV fostula and pseudoaneurysm without significant change of renal function. |
