Extrauterine pregnancy after IVF occurs in 3% to 5 % of patients. Up until recently surgery - Fallopian tube removal - had been the only method for its treatment. Today it has become possible to avoid traumatic operation. With ultrasonic guidance the puncture of gestational sac, located outside the uterus, is made. A medicine that stops further development of pregnancy is injected into its cavity. The gestational sac fully resolves after this procedure.
