目的研究静脉性阳萎阴茎血流动力学异常所致彩色多普勒频谱变化。方法32例静脉性阳萎和85例心理性阳萎在海绵体血管活性药物注射后，应用双功能超声（Biosound-AU4USA）进行检查，观察海绵体动脉和背深静脉血流频谱变化。结果彩色多普勒频谱显示静脉性阳萎海绵体动脉在整个舒张期或舒张早、中期有前向血流，约94％背深静脉存在持续血流。结奋静脉性阳萎在彩色多普勒频谱上有特征性表现，对本病诊断有一定价值。
Objective To study the changes of color Doppler spectrum caused by hemodynamic abnormalities of penile vein. Methods 32 cases of venous impotence and 85 cases of psychological impotence were examined by biosound-AU4USA after cavernosal vasoactive drug injection. The changes of blood flow spectrum in cavernosal artery and dorsal-veins were observed. Results Color Doppler spectrum showed venous occlusion cavernous arteries in the diastolic or early diastolic, interphase forward blood flow, about 94% of the dorsal veins continuous blood flow. Venous impotence in the color Doppler spectrum has a characteristic performance of the diagnosis of the disease have some value.
