High-flow priapism results from disruption of the intercavernosal artery resulting in an arteriocavernosal fistula and is rarely encountered in the pediatric and adolescent population. Clinically it manifests as a painless, prolonged erection after perineal trauma. Treatment has ranged from expectant management to open surgical exploration with vessel ligation. Internal pudendal arteriogram and superselective embolization with autologous blood clot has emerged as a safe and effective treatment modality in the young male population. Here the authors present 3 patients with high-flow priapism and discuss management of this rare clinical entity.
