Background. Priapism, persistent erection without arousal, can be classified into low-flow (venous or ischemic) and high-flow (arterial or non-ischemic). The diagnosis of high-flow priapism can be confirmed by colour Doppler and arteriography and it is usually treated by the endovascular embolization.
Case report. We present a case of a 20-year-old man with a post-traumatic high-flow priapism as a result of the previous perineal trauma. After a period of watchful waiting and an unsuccessful attempt at endovascular embolization using the resorptive gelatinous foam he was successfully treated by the endovascular embolization using N-butylcyanoacrylate.
Conclusions. High-flow priapism can be successfully treated by the endovascular embolization, but the optimal choice of the embolization agent and a careful technique is essential.
