Abstract:
We present a case of a 24 year old man who presented with high flow priapism. Priapism is defined as an erection lasting four or more hours, either after or unrelated to sexual stimulation. Priapism can be categorized into low-flow, stuttering, and high-flow types, each with unique mechanisms and treatments. High-flow priapism is caused by an abnormal communication between the artery and sinusoids of the penis, often in the form of an arteriovenous fistula. Super-selective embolization is the treatment of choice for high-flow priapism if conservative measures fail. Super-selective embolization is associated with an 80% success rate and a low chance of post-procedure erectile dysfunction.
