Observation on changes of lowerlimb veins in women before and after delivery by twodimensional ultrasound and color Doppler flow imaging

　　【Abstract】 AIM: To observe the changes of the lowerlimb venous system of women before and after delivery,to explore the causes and incidence of the lowerlimb venous thrombosis during gestation and puerperium, and to discuss the diagnostic value of twodimensional(2D) ultrasound and color Doppler flow image(CDFI). METHODS: Ninetysix pregnant and postpartum women were recruited for the study. Femoral veins, great saphenous veins and small saphenous veins were assessed in both lower limbs using 2D ultrasound and CDFI. 应用价值. 方法： 利用二维及彩色多普勒超声测量96例孕、产妇不同时期的股静脉及大、小隐静脉的内径，观察血管内血流自显影、有无血栓及彩色多普勒血流显像情况. 结果： 随着孕龄增加，下肢静脉内径逐渐增宽，大隐静脉表现最为显著（P
