Identification of the prostatic arteries (PAs) is one of the most challenging aspects of prostate artery embolization for treatment of benign prostatic hyperplasia-associated lower urinary tract symptoms. Operators require a detailed understanding of the prostate arterial anatomy to ensure technical and clinical success with minimal complications. Due to substantial variability in internal iliac artery branch patterns and specifically the origin of the PA, we focus on 3 clinically relevant classification systems used to categorize the pelvic vasculature. These include classification systems to understand the internal iliac artery branching pattern, PA origin variation, and intraprostatic branching.
