作者回顾性分析了 2 47例经双核素阴茎海绵体血液动力学动态检查 (Penograme) ,确诊为静脉性勃起功能障碍患者 [阴茎动脉系统显像指数 (PIA) 15 8.8± 6 7.5 ,阴茎静脉系统显像指数 (PIV) - 6 3.7± 12 .4]的硬度测试仪 (Rigiscan)资料。 2 47例中 ,周径变化线或硬度指数高点间连线呈“锯齿波”样变化者 196例 ,其PIA 142 .1± 45 .9,PIV - 5 7.6± 5 .1;呈“斜向降低”者 40例。PIA 145 .9± 5 3.2 ,PIV - 6 4.2± 7.6 ;无变化者 (未勃起 )者 11例 ,PIA140 .4± 47.1,PIV - 6 0 .9± 9.8;三种变化之间 ,PIA、PIV无统计学差异 (P >0 .0 5 )。作者认为 ,“锯齿波”及“斜向降低”样变化是静脉性勃起功能障碍Rigiscan检查的主要表现 ,其机理是因为静脉回流过快导致阴茎海绵体内压力不稳定甚至渐降低所至
The authors retrospectively analyzed a panel of 477 patients with venous erectile dysfunction diagnosed with penograme (penis arterial imaging system, penis arterial system imaging index (PIA) 15 8.8 ± 7.5 7.5, penile venous system Development Index (PIV) - 6 3.7 ± 12 .4] Rigiscan data. Of the 474 cases, 196 cases were found to have a “sawtooth” pattern with changes in the diameter of circumference or hardness index, with PIA 142.1 ± 45.9 and PIV -5 7.6 ± 5.1; To reduce “those 40 cases. PIA 145.9 ± 5 3.2, PIV - 6 4.2 ± 7.6; 11 patients without change (no erection), PIA140.4 ± 47.1, PIV - 60.9 ± 9.8; PIA, PIV No significant difference (P> 0.05). The author believes that the ”sawtooth wave“ and ”diagonal down" kind of change is the main manifestation of venous erectile dysfunction Rigiscan check, the mechanism is because of excessive venous return pressure penile sponge body is unstable or even decreased gradually
