Angiography > Exams & Procedures > Renal Artery Embolization

This is an arterial study performed similar to a renal angiogram. The purpose of this procedure is to block the blood supply to the kidney (before nephrectomy surgery) or a specific region of the kidney for abnormal blood flow or bleeding.

The procedure takes about one to two hours.
