The use of ultrasonic echo technique in the diagnosis of developmental anomalies of the uterus.

In the course of the fusion of the Müllerian ducts various anomalies of the uterus may be observed depending on the length of the septum between them. These anomalies can be recognized by the "B-scan" ultrasonic echo technique. Anomalies in pregnancy and puerperium were diagnosed in five cases and all of them were confirmed by clinical examination. The ultrasonic echo technique was applied in cases where manual examination revealed a uterus differing in shape from normal, the patient had a breech presentation in her previous or present pregnancy; and the involution of the uterus was slow. All the patients were multiparas and had breech presentation in their previous pregnancies. In four of the present pregnancies breech presentation was established and in three cases pregnancy was terminated before the thirty-seventh week. The involution of the uterus in the puerperium was generally slow.
