Twelve patients underwent balloon-occlusion prostatic artery embolization (PAE) at a single center. Bilateral prostatic artery catheterization was achieved in all patients, but unilateral embolization was performed in 1 patient as a result of the presence of a prostatic arteriovenous fistula. Mean International Prostate Symptom Score and quality-of-life score decreased by 15 ± 7 (P < .01) and 4 ± 1 (P < .01) points, respectively, over a mean follow-up period of 22 weeks ± 8. Only self-limiting minor complications were encountered. The initial experience with balloon-occlusion PAE suggests that it is technically feasible and can be performed safely.
