[Ultrasonic images the day after voluntary termination of a pregnancy]

We have studied 75 cases of uterine echography, obtained 24 hours after an induced abortion. In 2 out of 3 cases, the uterus was not empty and, in a majority of cases, a pseudo-organized image was observed. The images displayed were a central trans-sonic zone, limited by a line of echoes and containing some echoes which are less or more organized. A few aspects were very difficult to diagnose from a persisting pregnancy.
