Angiographic Findings Relevant to Prostatic Artery Embolization in Patients with Prostate Cancer

Abstract

The 2014–2018 angiograms of 58 patients with prostate cancer were retrospectively analyzed to illustrate angiographic findings during prostatic artery embolization. Arteriovenous fistulae were observed in 6 patients (6/58, 10.3%), with no difference between patients with or without prior iodine-125 seeds implantation (5/48, 10.4% vs 1/10, 10.0%; P > .05); tumor staining was not detected. The origins of the prostatic arteries included the internal pudendal artery (n = 45, 32.4%), the superior vesical artery (n = 38, 27.3%), the obturator artery (n = 28, 20.1%), the gluteal-pudendal trunk (n = 21, 15.1%), the inferior gluteal artery (n = 3, 2.2%), the accessory pudendal artery (n = 3, 2.2%), and the superior gluteal artery (n = 1, 0.7%).
