[Treatment of ectopic pregnancy by transvaginal ultrasonography-guided puncture and local application of methotrexate].

The early detection of ectopic pregnancy--using transvaginal sonography, beta-human chorionic gonadotropin determination in blood and laparoscopy--allow us to perform conservative therapeutic approaches to preserve future fertility. The authors report their experiences on five patients treated by local administration of methotrexate. The drug was injected to the ectopic gestational sac by transvaginally performed, sonographically directed puncture. The technique of the method, the criteria of selection and follow-up of patients have been discussed. Giving an overview on the other conservative methods, their increasing role is suggested in the management of early ectopic pregnancies.
