High-Flow Priapism Embolization

Synonyms : arteriocavernosal fistula embolization, endovascular priapism treatment

Background and indications

High-flow priapism is a prolonged erection caused by an arteriocavernosal fistula, often after perineal trauma. Unlike low-flow (ischemic) priapism, it is not an immediate emergency but requires treatment to prevent complications.

Benefits

Targeted fistula treatment with erectile function preservation in most cases.

Procedure

A catheter is guided via the femoral artery to the internal pudendal artery then cavernous artery. The fistula is embolized with resorbable gelatin (preferred for erectile function preservation) or microcoils. The procedure lasts 1-2 hours.

Risks

Erectile dysfunction (usually transient with resorbable gelatin), fistula recurrence requiring repeat embolization.

Recovery and follow-up

One-night hospitalization. Follow-up consultation at 1 month with erectile function assessment.

Practical information

Local anesthesia. Outpatient procedure (return home the same day).
