During pregnancy one should largely avoid invasive and radiological diagnostic methods. However, real-time sonography and venous occlusion plethysmography yield non-hazardous information on venous morphology and venous function. It became possible to demonstrate by means of these examination methods that the diameters of the veins are enlarged in pregnancy compared to the situation post partum. The difference in significant. Venous occlusion plethysmography points to a deterioration of venous function post partum, since the difference to the values in the third trimenon is not significant. Venous function measurement often pointed to the existence of an obstacle to flow during pregnancy, whereas sonographically a dilatation of the veins was revealed the existence of an obstacle to flow represented by the pregnant uterus. Hence, it appears meaningful to combine both investigation methods to confirm the occurrence of venous changes during pregnancy.
孕期应尽量避免采用侵入性和放射学诊断方法。然而，实时超声检查和静脉阻塞体积描记法可提供有关静脉形态和静脉功能的无害信息。通过这些检查方法能够证明，与产后相比，孕期静脉直径会增大。这种差异很显著。静脉阻塞体积描记法表明产后静脉功能会恶化，因为与孕晚期的值相比差异不显著。静脉功能测量常常显示孕期存在血流障碍，而超声检查则显示静脉扩张，提示存在由妊娠子宫导致的血流障碍。因此，将这两种检查方法结合起来以确认孕期静脉变化的发生似乎是有意义的。
