用彩色多普勒超声血流显像配合阴茎海绵体内血管活性药物注射（ＩＣＩ），观察３６例阴茎勃起功能障碍患者双侧阴茎海绵体动脉收缩期峰血流速度（ＰＳＶ）、舒张末期血流速度（ＥＤＶ）及阻力指数（ＲＩ）。结果表明：（１）１１例患者做ＩＣＩ前用彩色多普勒超声不能测出上述指标；（２）２５例在ＩＣＩ前测得ＰＳＶ、ＥＤＶ参数与３６例ＩＣＩ后ＰＳＶ、ＥＤＶ参数有显著性差异。本文并对多普勒超声在诊断血管性ＥＤ的价值及可能发生的误差进行讨论。
Color Doppler flow imaging with intracapsular vasoactive drug injection (ICI), 36 cases of erectile dysfunction in patients with bilateral penile cavernous systolic peak blood flow (PSV), end-diastolic blood flow Speed (EDV) and resistance index (RI). The results showed that: (1) The above indexes were not detected by color Doppler ultrasound in 11 patients before ICI; (2) PSV and EDV parameters of 25 patients before ICI and 36 patients after ICI were significant difference. This article also discusses the value of Doppler ultrasound in the diagnosis of vascular ED and possible errors.
