睾丸动脉舒张期反向血流的临床意义

Forming of reversal of diastolic plateau in testis and its value of clinical application

目的探讨阴囊急症中睾丸动脉舒张期反向血流的形成及其临床应用价值。方法回顾124例阴囊急症高频彩色多普勒超声检查结果，重点分析精索内动脉及其分支的多普勒频谱形态变化，并与治疗结果对照。结果在124例中共检出10例动脉舒张期反向血流，包括睾丸不全扭转7例，急性睾丸附睾炎2例，鞘膜积液伴急性感染1例。检出舒张期反向血流的血管为精索内动脉末段及包膜动脉和（或）睾丸穿隔动脉。8例施行手术均发现睾丸存在不同程度供血障碍。结论精索内动脉及其分支舒张期反向血流可作为睾丸急性血运障碍的评判指标，其临床应用值得进一步研究。

Objective To study the forming of reversal of diastolic plateau in testis in acute scrotal diseases and its value of clinical application. Methods One hundred and twenty-four patients with acute scrotal diseases were examined by color Doppler ultrasound with 10 - 13 MHz linear array transductor, analyzed emphatically the flow spectral waveform of testicular artery and its branches, compared with their therapy outcomes. Results In 10 of 124 cases with acute scrotal diseases, reversed diastolic flow was checked out by pulse Doppler in testicular artery, envelope artery, and/or transmediastinal artery. Of 10 cases, incomplete testicular torsion was in 7, acute epididymo-orchitis in 2, and hydrocele with inflammation in 1. Eight patients underwent surgery, confirmed the loss of testicular tissue perfusion. Conclusions Reversal of diastolic plateau of testicular artery and its branches could be a useful index for evaluation of testicular tissue perfusion in acute scrotal diseases, its value of clinical application worth while more research.
