Prostate artery embolization (PAE) has emerged as a new treatment option for patients with symptomatic benign prostatic hyperplasia. The main challenges related to this procedure are navigating arteries with atherosclerosis and anatomical variations, and the potential risk of non-target embolization to pelvic structures due to the presence of collateral shunts and reflux of microparticles. Knowledge of classical vascular anatomy and the most common variations is essential for safe embolization, good clinical practice, and optimal outcomes. The aim of this pictorial essay is to illustrate the pelvic vascular anatomy relevant to PAE in order to provide a practical guide that includes the most common anatomical variants as well as to discuss the technical details related to each.
前列腺动脉栓塞术（PAE）已成为有症状的良性前列腺增生患者的一种新的治疗选择。与该手术相关的主要挑战包括在存在动脉粥样硬化和解剖变异的情况下引导动脉，以及由于存在侧支分流和微粒反流而导致对盆腔结构进行非靶栓塞的潜在风险。了解经典血管解剖结构和最常见的变异对于安全栓塞、良好的临床实践和最佳结果至关重要。本文的目的是阐述与PAE相关的盆腔血管解剖结构，以提供一份实用指南，其中包括最常见的解剖变异，并讨论与之相关的技术细节。
