Abstract
BACKGROUND: High-flow (non-ischemic) priapism is a rare urological condition usually related to blind trauma to the penis or perineum causing an arterial-lacunar fistula. It can be treated conservatively, but in some cases when conservative treatment fails, the interventional approach is indicated. In the past, only surgical treatment was available, which was associated with a significant risk of complications. Endovascular techniques use a novel approach and offer clinical benefits for the patient.
CASE REPORT: A 51-year-old man was admitted to the hospital after referral from the urology department with high-flow priapism related to blunt trauma. Angio-computed tomography showed extravasation of contrast medium to the corpus cavernosum, and angiography revealed a fistula between the distal segment of the left internal pudendal artery and corpora cavernosa. A successful endovascular microembolization of the arterial-lacunar fistula with the use of microcoils was performed. The postprocedural period was uneventful and the patient was discharged. Despite incomplete angiographic follow-up at 6 months, the initial symptoms were fully resolved with the absence of any erectile dysfunction and no recurrence of priapism occurred.
CONCLUSIONS: Post-traumatic high-flow priapism can be safely and effectively treated by endovascular means. Microembolization has proven to be successful and beneficial to preserve sexual functions.
