Abstract(s)

In 9 of 491 patients (1.8%) who underwent prostatic arterial embolization (PAE) for benign prostatic hyperplasia from March 2009-November 2013, prostatic arteries arose from the external iliac artery via an accessory obturator artery (AOA). Computed tomography angiography performed before the procedure identified the variant and allowed planning before the procedure. The nine AOAs were catheterized from a contralateral femoral approach. Bilateral PAE was technically successful in the nine patients. There was a mean decrease in international prostate symptom score of 6.5 points and a mean prostate volume reduction of 15.1% (mean follow-up, 4.8 mo) in the nine patients.
