The purpose of this study was to assess the relationship between the number of microcatheters required for prostatic artery embolization (PAE) and the anatomy of the prostatic artery (PA).
All consecutive patients who underwent PAE between May 2017 and December 2018 were included. The anatomical description of the PAs was assessed by both global cone beam computed tomography and selective angiography and data on the resources used, in terms of microcatheters, were prospectively collected.
A total of 215 consecutive patients (mean age, 66±8.7 [SD] years; range: 45-93 years), with a mean International Prostate Symptom Score of 21±7.4 (SD) and a mean prostate volume on magnetic resonance imaging of 88±38 (SD) mL (range: 30-200mL) underwent PAE. A single PA was observed in 347 hemipelvises (347/411; 84.4%) and double PAs in 64 (64/411; 15.6%). Eighty percent (173/215 patients) of PAEs were performed using a single microcatheter. Type I PA anatomy required significantly more microcatheters (1.15±0.39 [SD]; range: 1-3), than type II (1.04±0.19 [SD]; range: 1-2), type III (1.09±0.34 [SD]; range: 1-3) and type IV (1.06±0.27 [SD]; range: 1-2) (P=0.01 for all).
PAE is feasible with limited per-intervention changes in devices for all types of PA anatomy encountered. This could help in the design of appropriate reimbursement policies in various healthcare settings.
本研究旨在评估前列腺动脉栓塞术（PAE）所需微导管数量与前列腺动脉（PA）解剖结构之间的关系。
本研究纳入了 2017 年 5 月至 2018 年 12 月期间接受 PAE 的所有连续患者。通过全局锥形束计算机断层扫描和选择性血管造影评估 PA 的解剖描述，并前瞻性收集了微导管使用方面的资源数据。
共纳入 215 例连续患者（平均年龄 66±8.7[标准差]岁；范围：45-93 岁），国际前列腺症状评分（IPSS）平均为 21±7.4（标准差），磁共振成像前列腺体积平均为 88±38（标准差）mL（范围：30-200mL）。347 个半骨盆（347/411；84.4%）观察到单个 PA，64 个半骨盆（64/411；15.6%）观察到双 PA。80%（215 例患者中的 173 例）的 PAE 使用单个微导管进行。I 型 PA 解剖结构需要明显更多的微导管（1.15±0.39[标准差]；范围：1-3），而 II 型（1.04±0.19[标准差]；范围：1-2）、III 型（1.09±0.34[标准差]；范围：1-3）和 IV 型（1.06±0.27[标准差]；范围：1-2）需要的微导管更少（P=0.01 所有类型）。
对于遇到的所有类型的 PA 解剖结构，PAE 都可以在干预过程中使用有限的器械变化来完成。这有助于在各种医疗保健环境中设计适当的报销政策。
