Prostate Embolization for Benign Prostatic Hyperplasia

"Each patient will have a selective internal iliac arteriogram, and as necessary, an arteriogram of the anterior division of the internal iliac artery performed to identify the prostatic arterial supply. This typically arises from the inferior vesicle artery (also known as the prostatic artery), but may have supply from the superior vesicle, the internal pudendal or obturator branches as well.~The prostatic arteries will be selected using standard micro-catheter technique. Embolization of the prostate will be performed with 300 to 500 um sized TAGM (Embosphere® Microspheres, Merit Medical, South Jordan, UT). The embolization endpoint will be absence of the normal blush of the prostate on post embolization angiography and stasis of flow in the prostate arteries."
