Prostate artery embolization is a minimally invasive treatment for benign prostatic hyperplasia, and imaging is indispensable for the technical success of this procedure; however, imaging is a major source of radiation exposure for patients and healthcare providers. Radiation emission during prostate artery embolization procedures at a single institution was evaluated to determine radiation exposure with the goal to work toward minimizing exposure. All patients at a single institution that underwent outpatient unilateral/bilateral prostate artery embolization between 4 January 2019 and 16 November 2021 were retrospectively evaluated; data collected included body mass index, prostate volume, and indications for prostate artery embolization. Technical parameters recorded were air kerma, procedure time, fluoroscopy time, number of acquisitions, and intra-procedural imaging modalities. Fisher's t-test, ANOVA, and chi-square analyses were used as appropriate for statistical analysis (P < 0.05). Overall, 56 patients were included in the study. Body mass index (obesity; P = 0.0017) was a significant predictor of increased air kerma; prostate size and bilateral vs. unilateral prostate artery embolization were not significantly associated with increased air kerma despite the number of acquisitions being significantly different between bilateral and unilateral embolization (P = 0.0064). When evaluating radiation exposure during prostate artery embolization, increased body mass index significantly predicted increased air kerma. Contrary to the literature, the extent of embolization (bilateral vs. unilateral) was not associated with increased air kerma regardless of higher acquisitions and procedure time associated with bilateral prostate artery embolization. Increased radiation protection efforts should be considered for patients with higher body mass index to protect patients and practitioners.Health Phys. 124(0):000-000; 2023.
前列腺动脉栓塞术是治疗良性前列腺增生的一种微创治疗方法，该手术的技术成功离不开影像学的支持；然而，影像学也是患者和医护人员接受辐射的主要来源。本研究旨在评估单一机构前列腺动脉栓塞术的辐射发射情况，以确定辐射暴露，并努力将其降至最低。对 2019 年 1 月 4 日至 2021 年 11 月 16 日期间在单一机构接受门诊单侧/双侧前列腺动脉栓塞术的所有患者进行回顾性评估；收集的数据包括体重指数、前列腺体积和前列腺动脉栓塞术的适应证。记录的技术参数包括空气比释动能、手术时间、透视时间、采集次数和术中成像方式。Fisher's t 检验、方差分析和卡方检验用于适当的统计分析（P < 0.05）。共有 56 名患者纳入研究。体重指数（肥胖；P = 0.0017）是空气比释动能增加的显著预测因素；尽管双侧前列腺动脉栓塞术与单侧前列腺动脉栓塞术的采集次数存在显著差异，但前列腺大小和双侧与单侧前列腺动脉栓塞术之间并无明显相关性，与空气比释动能增加无关（P = 0.0064）。评估前列腺动脉栓塞术期间的辐射暴露时，体重指数增加显著预测空气比释动能增加。与文献相反，栓塞范围（双侧与单侧）与空气比释动能增加无关，尽管双侧前列腺动脉栓塞术与更高的采集次数和更长的手术时间相关。应考虑为体重指数较高的患者增加辐射防护措施，以保护患者和医护人员。健康物理。124（0）：000-000；2023 年。
