title: High-flow priapism caused by a pseudoaneurysm and an arteriocavernosal fistula: clinical and radiological approach of 3 cases.
abstract: OBJECTIVE
  We report three cases of high-flow priapism in three young patients who presented erectile dysfunction after perineal trauma.
  
  
  METHODS
  Complete clinical evaluation, blood tests, color Doppler ultrasonography (US), arteriography and selective embolization were performed.
  
  
  RESULTS
  The clinical history and physical assessment were compatible with high-flow priapism. Color Doppler US showed a pseudoaneurysm and an arteriocavernosal fistula, which was confirmed and embolized using arteriography.
  
  
  CONCLUSIONS
  High-flow priapism has a characteristic clinical presentation and physical examination. The radiologist has an important role in the diagnosis and treatment of this pathology. Color Doppler US and arteriography are essential in the diagnosis and allow embolization of the vascular injury. Prognosis is usually good.
