Anatomical variants in prostatic artery embolization in treatment of benign prostatic hyperplasia

Abstract

Prostatic artery embolization (PAE) is a safe minimally invasive, image guided therapy for symptomatic relief in patients with prostate enlargement/benign prostatic hyperplasia associated with benign prostatic hyperplasia with minimal post procedural complications. A thorough understanding of PA anatomy is required for treating BPH with PAE in order to improve technical success, decrease problems related to non-target embolization, shorten the procedure, and limit radiation exposure. There is insufficient data to support the regular use of preoperative CTA and intraoperative CBCT to improve safety or effectiveness. In this regard, randomised controlled trials are necessary. In our study we found that the most common origin was type I prostatic artery with nearly one third of the cases of the prostatic artery origin was from this type.
