探讨前列腺癌患者的前列腺动脉造影表现。

回顾性分析2014年10月至2019年12月经活检证实前列腺癌并接受PAE治疗患者的血管造影表现。观察前列腺动脉（PA）数目、起源以及异常造影表现，通过国际前列腺症状评分（IPSS），生活质量（QoL）和并发症等指标评估造影异常患者PAE治疗前列腺癌源性下尿路梗阻或血尿的疗效。

61例患者完成121侧盆腔造影（1侧盆腔由于髂内动脉闭塞未行造影），共显影147支PAs。PA起源包括阴部内动脉（46例，31.3%），膀胱动脉（40例，27.3%），闭孔动脉（31例，21.1%），臀-阴动脉干（23例，15.7%），臀下动脉（3例，2.0%），阴部副动脉（3例，2.0%）和臀上动脉（1例，0.6%）。6例患者髂内动脉造影可见动静脉瘘，但术前及术后随访时间点IPSS、QoL评分差异均有统计学意义（P值均< 0.05）。所有患者术后随访均未出现盆腔脏器缺血坏死等严重并发症。

前列腺癌患者的PA起源复杂多样、高度可变。部分前列腺癌患者存在动静脉瘘，但只要术中选择合适的栓塞材料，PAE治疗前列腺癌源性下尿路梗阻或血尿仍然是安全、有效的。

To illustrate angiography findings in patients with prostate cancer during prostatic artery embolization (PAE).

The 2014.10-2019.12 angiograms of patients witha biopsy-proven diagnosis of prostate cancer during PAE were retrospectively analyzed. The number and origin of prostate artery (PA) and abnormal angiographic manifestations were observed. International Prostate Symptom Score (IPSS), quality of life (QoL) and complications at 3 and 12 months after PAE were collected to evaluate the efficacy of PAE in patients with abnormal angiographic manifestations.

One hundred and twenty-one pelvic sides were detected (One pelvic side was not evaluated because of the internal iliac artery occlusion) and 147 PAs were identified. The origins of the PAs included the internal pudendal artery (n = 46, 31.3%), the vesical artery (n = 40, 27.3%), the obturator artery (n = 31, 21.1%), the gluteal-pudendal trunk (n = 23, 15.7%), the inferior gluteal artery (n = 3, 2.0%), the accessory pudendal artery (n = 3, 2.0%), and the superior gluteal artery (n = 1, 0.6%). Arteriovenous fistula was present in6 patients and significant improvements were observed in the 3rd and 12th month IPSS and QoL (P < 0.05 for both). No major complications were observed.

The origin of PAs was complex and highly variable. Although arteriovenous fistula was present in some patients with prostate cancer, PAE was still safe and effective as long as suitable embolic particles were used.
