Bilateral Arterial Embolization of the Prostate Through a Single Prostatic Artery: A Case Series

Peri-prostatic shunts are frequent during PAE, carrying the risk of non-target embolization of penis/corpus cavernosum or rectum but also the potential advantage to irrigate the contralateral lobe. Sometimes, bilateral embolization is impossible, carrying the risk of limited clinical success. The possibility to reach contralateral prostatic territory from the ipsilateral prostatic artery (PA) and embolize it via peri/intra-prostatic anastomoses could be of interest in this situation. We describe a series of three consecutive patients (among 89 consecutive patients treated by PAE for symptomatic BPH) who underwent successful embolization of both prostatic lobes through catheterization of a PA on only one side. All patients had clinical success after a mean follow-up of 3.3 months. Dosimetry of these three procedures indicates that there may be radiation dose savings.
