[Ultrasonic diagnosis in hazardous or irregular early pregnancies]

747 cases of ultrasonic B-scan examinations carried out over 528 patients, in threatened or deranged stage of early gestation, are reported, and this method is hereby recommended in therapeutic check-ups of imminent abortions. Concerning cases of missed abortion it is established on the basis of individual materials and other publications that the ultrasonic technique cannot be presently substituted by any other methods. The application of ultrasonic B-scan for the diagnosis and exclusive diagnosis of hydatidiform mole, ectopic pregnancy and incomplete abortions is discussed.
