[High flow priapism. Case report].

Area of Science:

• Urology
• Interventional Radiology
• Vascular Surgery

Background:

• Priapism, a prolonged erection, can lead to erectile dysfunction and requires prompt diagnosis and management.
• High-flow priapism, often secondary to perineal trauma and arteriovenous fistula (AVF) formation, presents unique diagnostic and therapeutic challenges.
• Literature review indicates varied etiologies and presentations of priapism, necessitating a comprehensive approach to differential diagnosis.

Observation:

• A patient presented with a four-year history of recurrent priapism.
• Clinical and radiological assessments were performed to determine the underlying cause.
• An arteriovenous fistula involving the internal pudendal artery was identified as the etiology.

Findings:

• The patient underwent successful embolization of the internal pudendal artery.
• Post-embolization, the patient experienced complete resolution of priapism.
• Radiological imaging confirmed the closure of the arteriovenous fistula.

Implications:

• Percutaneous embolization of the internal pudendal artery is a highly effective treatment for high-flow priapism secondary to AVF.
• This minimally invasive approach offers a viable solution for refractory priapism cases, preserving erectile function.
• The findings support interventional radiology as a key modality in managing complex vascular abnormalities causing priapism.
