Duplicated Prostate Artery Central Gland Blood Supply: A Retrospective Analysis and Classification System.

Angiograms and cone-beam computed tomography scans of 36 consecutive prostate artery embolization patients (72 hemipelves) between October 2014 and February 2018 were reviewed. The hemipelves were classified according to the presence of dual central gland (CG) blood supply and the pattern of vascularization: Type 1 with a single CG blood supply (83.3%; n = 60); Type 2 with 2 independent CG arteries with overlapping territories (9.7%; n = 7); and Type 3 with 2 independent CG arteries with isolated territories (7%; n = 5). Up to 20% of pelvic sides may have more than 1 independent CG prostate artery that should be searched for during prostate artery embolization.
