Fig. 1From: Prostatic artery embolization with polyethylene glycol microspheres: evaluation in a canine spontaneous benign prostatic hyperplasia modelPAE procedure in a dog with spontaneous BPH. Left internal iliac arteriogram (a) shows the prostatic artery arises from the anterior division of the internal iliac artery. b Shows the microcatheter in the left prostatic artery. The white arrow indicates the cranial branch (caudal vesical artery) of the prostatic artery. c Shows the tip of microcatheter in the prostatic branch, where microspheres are injected. d Shows radiogram immediated after PAE on the left side, indicating the mixture of microspheres with contrast medium injected into part of the left lobeBack to article page
