The vein impedance blood stream charts were analysed in 32 pregnant women with gestational age between 38-42 weeks and in 31 healthy nonpregnant women as well. Measurement included maximal venous out flow (MVO), 3-sec venous outflow (VO), venous capacity (VC) and arterial blood flow (ABF). The results showed that all the parameters mentioned above were significantly lower in pregnant women either in 3rd trimester or at post partum when compared with nonpregnant women (P < 0.01). All parameters were increased after delivery. The significant change was only seen in VC. It suggested that the vein impedance blood stream chart might be used as an early diagnostic tool for thrombophlebitis occurred in lower extremities after delivery.
对32名孕周在38 - 42周的孕妇以及31名健康未孕女性的静脉阻抗血流图进行了分析。测量指标包括最大静脉流出量（MVO）、3秒静脉流出量（VO）、静脉容量（VC）和动脉血流量（ABF）。结果显示，与未孕女性相比，上述所有参数在孕晚期或产后的孕妇中均显著降低（P < 0.01）。所有参数在分娩后均升高。仅在VC方面出现了显著变化。这表明静脉阻抗血流图可能作为产后下肢血栓性静脉炎的早期诊断工具。
