Introduction:
Selective angioembolization for high flow priapism (Step-by-step guide).
Aim:
Describe the indications and techniques of angioembolization for high flow priapism.
Methods:
We outline patient selection, preparation, technique, outcomes, and potential complications of angioembolization for high flow priapism as supported by the literature.
Main Outcome Measure:
The effectiveness of embolization for treating high flow priapism.
Results:
Transarterial embolization is minimally invasive, low risk, and effective method from managing high flow priapism. Success rates range from 70% to 87% depending on the type of agent used for embolization. Side effects include erectile dysfunction with a reported rate of 7%-19%. Complications may be mitigated by embolizing as selectively as possible and using temporary embolic agents.
Conclusion:
Embolization is a safe and effective treatment for nonischemic, high flow priapism in patients who have not responded to conservative management.
