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.engHSJ UROAgedAngiography, Digital SubtractionArteries/abnormalitiesEmbolization, Therapeutic/methodsProstate/blood supplyProstatic Hyperplasia/complicationsProstatic Hyperplasia/diagnosisProstatic Hyperplasia/therapyRetrospective StudiesTomography, X-Ray ComputedTreatment OutcomeVascular Malformations/complicationsVascular Malformations/diagnosisThe Role of Accessory Obturator Arteries in Prostatic Arterial Embolizationjournal article
