26歳男.会陰部打撲後に発症した流入過剰型持続勃起症(high flow priapism)に対して片側陰茎深動脈塞栓術が有効であったA 26-year-old man with high flow priapism after blunt perineal trauma, is described herein. Patient evaluation included intracavernal blood-gasometry, cavernography, color flow Doppler sonography. The blood-gasometry showed pH 7.413, pO2 77.9 mmHg, pCO2 41.0 mmHg, HCO2- 26.1 mmol/L, BE 2.0 mmol/L. By direct cavernosography, pooling of contrast agent was seen at the root of the penis. Color flow Doppler sonography revealed pulsatile, turbulent flow within left corpus cavernosum. Our case was diagnosed as high flow priapism from these findings. Detumescence was not achieved by an alpha-adrenergic agent. Superselective embolization of the deep artery of the penis with autologous blood clot was performed with good results. Our case demonstrates that this procedure is a safe and effective therapy for high flow priapism and that erectile function can return to normal.
