Treatment of posttraumatic high-flow priapism in 8-year-old boy with percutaneous ultrasound-guided thrombin injection.

Treatment of high-flow priapism varies and has included transcatheter embolization when conservative approaches fail. We present the case of an 8-year-old boy with high-flow priapism, who was treated with ultrasound-guided thrombin injection because of encouraging experience with the method obtained when treating aneurysms and pseudoaneurysms. This procedure appears to be a useful alternative to transcatheter embolization and results in no radiation exposure.
