[Blood flow measurements of neovascularization in tubal pregnancy].
In a retrospective study the results of vagino- and colour flow Doppler sonography of 23 tubal pregnancies verified by surgery were documented. Due to the neovascularisation in the trophoblast tissue the vascular impedance was elevated in all cases. The mean value of all pulsatility indices was 0.85 +/- 0.2. The direct signs of tubal pregnancy were seen in only 20 cases with vaginosonography alone. The combination of vagino- and colour flow Doppler sonography offers the chance of an earlier detection (5th week of pregnancy) of a tubal pregnancy.
