Coil embolization of extra-prostatic arteries. (a) The middle rectal artery (white arrow) and prostatic artery (black arrow) share a common trunk with short distance between middle rectal artery and prostatic artery. To safely embolize the prostatic artery with particles, the middle rectal artery can be embolized with coils, (b) Selective injection of the middle rectal artery prior to coil embolization, (c) DSA imaging of the prostatic artery after coil embolization (white dotted arrow) of the middle rectal artery shows filling of the prostate without filling of the rectum. Following these steps, the prostatic artery can now safely be embolized with particles.
