RESUMO
Introduction: High-flow priapism is rare, uncontrolled arterial inflow, preceded by penile or perineal trauma and arterial-lacunar fistula. There are several ways to treat high-flow priapism, i.e., conservative management, the use of ice packs, mechanical decompression, surgery, and super-selective arterial embolization. Embolization is currently widely accepted in patients who fail from conservative management. This study aimed to report the use of Gelfoam and microcoil embolization in recurrent high-flow priapism compared to PVA embolization. Case Study: A 36-year-old man complained of prolonged erection. The erection occurred three days before admission while waking up in the morning, not accompanied by either sexual stimulation or pain. There was a history of fall four days ago in the afternoon, with the patient's groin hitting a rocky ground. Physical examination revealed an erect penis, which felt warm, with an EHS of 4. Blood gas analysis of the corpus cavernosum showed bright red blood with a pH of 7.47, pCO2 of 23.6, pO2 of 145, HCO3 of 17.3, BE of -6, and SaO2 of 99%. Doppler ultrasound examination of the penis showed high-flow priapism. Embolization with PVA was performed, and there were decreased complaints. A few hours later, the erection occurred. Reevaluation was then performed and continued with embolization using Gelfoam and microcoil. There were immediate successful results (EHS of 3) accompanied by a decrease in symptoms. Long-term follow-up has shown a return to normal erectile function six months following the injury. Conclusion: Priapism may happen due to various etiologies. Differentiating high-flow and low-flow is paramount during the acute phase because of different treatment strategies. Conservative management may be applied to high-flow priapism. If conservative management fails, embolization may be attempted. The choice of embolization agent must be taken into account.
