Abstract
Non-ischemic, high-flow priapism is defined as the state of painless and permanent erection of the penis which generally develops by perineal trauma. Selective transarterial embolisation is one of the treatment options. We present an 18-year-old men who had complaints of painless and permanent erection after a blunt perineal trauma. Colour Doppler ultrasound revealed a pseudoaneurysm and fistula at the left cavernosal artery. Hence autologous blood clot injection was performed to embolise the pseudoaneurysm. Due to the recanalization on the postprocedural seventh day, second embolisation was performed. One month after the second procedure, colour Doppler ultrasound revealed a 50% shrink but mild refilling in the pseudoaneurysm, whereas complete thrombus formation was observed on follow-up imaging. His priapism had fully recovered and erectile functions were totally normal at the six months and one year follow up. Autologous blood clot embolisation seems as a safe and successful treatment.
