310 patients with threatened abortion were examined by ultrasound. 86 cases showed empty gestational sacs of which 14 (16%) completed their pregnancy. All sacs were evaluated (and scored) with respect to size, shape, wall definition, trophoblastic reaction and position inside the uterus. Prediction of a non-viable pregnancy from a single ultrasound examination was achieved in some cases. However, this prediction could not be made in other cases before a follow-up ultrasound examination was performed. The proposed scoring system proved to be very helpful in identifying empty gestational sacs in which serial ultrasound examinations are highly required before termination of pregnancy.
