Our aim is to introduce the cavernous artery ondulation index (CA-OI) as a new parameter that could be accepted as an indirect indicator of vascular hemodynamics and also gives us information about the efficiency of erection.
A total of 27 patients with erectile dysfunction were evaluated with penile Doppler ultrasonography (PDUS). After injection of papaverine intracavernously, arterial diameter and peak-systolic and end-diastolic velocities were measured. For measuring at a standart time, five minutes after injection, bilateral cavernosal arteries were examined and gray scale and color Doppler US images through the long axis were recorded at the mentioned phases. Cavernosal artery ondulation index (CA-OI) showing the amount of ondulation was calculated for each subject using these images.
In 9 of total 27 patients, erection could not pass the tumescence phase with 3 flaccid phases, while the remaining 18 had full erection. Mean CA-OI values were measured as 2.51±0.37 mm, 3.15±0.38 mm, and 2.68±0.09 mm in normal, arterial insufficiency and venous insufficiency groups, respectively.
It is possible to differentiate the arterial insufficiency by using the cut-off value of CA-OI ≥ 2.5 values as a criteria.
我们旨在引入海绵体动脉波动指数（CA-OI）作为一个新的参数，该参数可作为血管动力学的间接指标，同时为勃起效率提供信息。
共评估了 27 例勃起功能障碍患者的阴茎多普勒超声（PDUS）。在海绵体内注射罂粟碱后，测量动脉直径和收缩期峰值及舒张末期速度。为了在标准时间测量，即注射后 5 分钟，检查双侧海绵体动脉，并在上述各期通过长轴记录灰阶和彩色多普勒 US 图像。使用这些图像为每位患者计算海绵体动脉波动指数（CA-OI），以显示波动量。
在总共 27 例患者中，有 9 例勃起不能通过肿胀期，出现 3 个疲软期，而其余 18 例有完全勃起。正常、动脉功能不全和静脉功能不全组的平均 CA-OI 值分别为 2.51±0.37mm、3.15±0.38mm 和 2.68±0.09mm。
通过将 CA-OI≥2.5 值的临界值作为标准，可以区分动脉功能不全。
