title: High-flow priapism treated with superselective transcatheter embolization using polyvinyl alcohol particles.
abstract: OBJECTIVE
  Priapism is a persistent erection of the penis not associated with sexual stimulation. High-flow priapism is caused by unregulated arterial inflow, usually preceded by perineal or penile blunt trauma and formation of an arterial-lacunar fistula. We present a case of high-flow priapism in a 13-year-old patient managed with polyvinyl alcohol particles.
  
  
  METHODS
  After obtaining informed consent of the parents of the minor, diagnosis was made with penile Color Doppler Ultrasound and confirmed with flush angiography. Selective arterial embolization was performed with the use of polyvinyl alcohol particles.
  
  
  RESULTS
  Complete detumescence was achieved without compromising the patient's erectile function.
  
  
  CONCLUSIONS
  The use of permanent occlusive agents like polyvinyl alcohol particles for embolization shows good occlusion rates compared to temporary agents. More studies are needed to find the safer and better agent for the treatment of high flow priapism without compromising erectile function.
