Summary
Selective embolization effectively treats post-traumatic priapism by addressing arteriovenous fistulas and pseudoaneurysms. Colour Doppler sonography aids in diagnosing the cause of priapism before treatment.
Area of Science:
- Urology
- Interventional Radiology
- Vascular Surgery
Background:
- Post-traumatic priapism is a rare but serious condition.
- Arteriovenous fistulas and pseudoaneurysms are common causes.
- Effective management is crucial to prevent long-term complications.
Purpose of the Study:
- To evaluate selective embolization for managing post-traumatic priapism.
- To assess the role of colour Doppler sonography in diagnosing causative lesions and planning embolization.
Main Methods:
- Six male patients with post-traumatic priapism were included.
- Selective angiography and embolization were performed.
- Colour Doppler sonography with grey-scale was used for pre-angiographic assessment.
Main Results:
- Angiography revealed intracavernosal arteriovenous fistulas in all patients and pseudoaneurysms in three.
- Successful embolization led to detumescence in all patients.
- Colour Doppler sonography localized causative lesions in four patients.
Conclusions:
- Selective embolization is a safe and effective treatment for post-traumatic priapism.
- Colour Doppler sonography is a useful pre-angiographic tool for lesion characterization and localization.
