Problems in ultrasonic monitoring of multiple pregnancies

Abstract

Ultrasound evidently is an ideal method of ensuring the early diagnosis of multiple pregnancy in humans and also affords an opportunity to measure individual fetal growth thereafter. In a program to study multiple pregnancies the majority were diagnosed early to allow adequate regular monitoring by ultrasound. Unexpected problems were encountered and the failure rate to obtain satisfactory fetal biparietal measurements was almost 3 times that in singleton pregnancies.
