INTRAUTERINE HAEMATOMA AN ULTRASONIC STUDY OF THREATENED ABORTION

Abstract
Ultrasonic scanning in patients with symptoms of threatened abortion occasionally revealed an echo-free area between the membranes and the uterine wall. The echo-free area was found in patients at 11-20 wk gestation who had a live fetus and is belived to represent blood. Seven smaller hematomas of less tha 35 ml gradually disappeared and the pregnancies continued until term. Three patients who had hematomas of more than 50 ml subsequently aborted or had a premature delivery.
