本文对26例经海绵体灌注造影诊断为静脉性阳萎的患者行彩色多普勒检查,并以11例功能性阳萎患者作为正常对照组.检测的结果经统计学处理证实阴茎海绵体动脉的舒张末期速度(EDV)和阻力系数(RI)在两组之间有显著性差异(P<0.05).以EDV≥4.3cm/s为界值,诊断的灵敏度为96.2%,特异性为77.3%;以RI≤85%为界值,诊断的灵敏度为86.5%,特异性为86.4%.本文对彩色多普勒超声在静脉性阳萎诊断中的价值以及和灌注性海绵体造影的关系进行了讨论.
In this paper, 26 cases of patients with venous impotence diagnosed by cavernosal perfusion imaging were examined by color Doppler, and 11 cases of functional impotence were used as normal control group.The results of the test confirmed by statistical analysis of penile cavernous artery (EDV) and resistance coefficient (RI) were significantly different between the two groups (P <0.05) .The diagnostic sensitivity and specificity of EDV≥4.3cm / s were 96.2% and 77.3 %, The sensitivity of diagnosis was 86.5% and the specificity was 86.4% when RI≤85% .The diagnostic value of color Doppler ultrasound in venous impotence and the relationship with perfusion cavernous angiography Discuss.
