Prostate Artery Embolization for Symptomatic Benign Prostatic Hyperplasia

Right femoral arterial puncture is performed under local anesthesia. The blood supply to the prostate is mapped by angiography of the iliac vessels and the prostate arteries. Microcatheters are used for super-selective catheterization of the right and left inferior vesicle arteries. Embolization is performed with a microcatheter to deliver microspheres of 300 micron diameter. The microsphere mixture is slowly injected under fluoroscopic guidance. The endpoint of embolization is flow stasis in the prostatic vessels with prostatic gland opacification, without reflux of the mixture to undesired arteries.
