[The value of vaginal ultrasonography in early pregnancy].

Heart action was detected in our first group of 150 pregnant women during the early period of pregnancy (5th to 8th week post menstruationem) in 25% at the end of the 5th week of pregnancy, in 85% at the end of the 6th and, in 100% in the 7th week. In our second group of 59 women with tubal pregnancy, confirmed by laparoscopy, it was possible to detect the extrauterine pregnancy transabdominally in 25% and transvaginally in 94.7% via sonography (p = 0.03). Extrauterine pregnancy was easier detectable by vaginosonography due to the proximity of the organ and the better power of resolution, as a direct sign of extrauterine ring formation surrounded by a circular wall-like structure.
