摘要
１６例静脉性阳萎在海绵体血管活性药物注射后，采用双功能彩色多普勒超声（ＤＣＤＳ）来监测血流动力学变化，并用３２例功能性阳萎作对照组。背深动脉监测指标：１．舒张期内径（ＡＤ），２．最大收缩期流速（ＰＳＶ），３．舒张末期流速（ＥＤＶ），４．阻力指数（ＲＩ），５．血流加速度（ＡＣＣ）。背深静脉监测指标：１．静脉内径（ＶＤ），２．血液流速（ＶＶ）。研究结果提示静脉性阳萎ＥＤＶ＞Ｏｃｍ／ｓｅｃ，ＲＩ＜１，均Ｐ＜０．０１。背深静脉显示持续性、高流速血液回流。我们认为采用ＤＣＤＳ监测对客观评估静脉性阳萎血流动力学变化和静脉性阳萎的诊断均有一定价值。
From Jun. 1995 to Mar. 1996, duplex and color doppler sonography (DCDS) combined with intracavernous injection of vasodilator was used on 48 cases with erectile dysfunction (ED) in order to study hemodynamics of venous impotence. Sixteen cases showed venous ED, 32 cases were functional ED served as a control group. The results of patients with venous ED suggest that end-diastolic velocity (EDV) of cavernous artery is higher than zero cm/sec, resistance index (RI) of cavernous arterial flow is lower than 1 and deep dorsal vein is displayed persistent blood flow. The results of control group suggest that the EDV of cavernous artery is lower than or epual to zero cm/sec, the RI of cavernous arterial flow is higher than or epual to 1 and deep dorsal vein is displayed intermittent blood flow. The results showed that venous ED may be evaluated by DCDS for there are siginficant difference between two groups (P<0.01).
