[Vaginal endosonography in extrauterine pregnancy].

The real value of vaginal sonography in the early diagnosis of ectopic pregnancy was assessed in 12 cases where ectopic pregnancy was suspected by clinical evolution and levels of B-HCG, and subsequently confirmed by microlaparotomy. The results were compared with those obtained with abdominal sonography and values of B-HCG. Vaginal sonography gave no false negatives and the percentage of false positives was 16.6%. The most typical echographyc images were: 1. Adnexal Mass (50%), 2. Pseudoring (42%), 3. Yolk sac &/or Embryo &/or Heart rate (25%). Values of B-HCG greater than 600 mIU/IS without embryo from 35th day are highly suspicious with regard to ectopic pregnancy.
