Abstract

An ultrasound performed during the 1st trimester is crucial in diagnosing early pregnancy failure and ectopic pregnancy. As sonographic spatial resolution improved 1st trimester sonography increasingly also offers early pregnancy screening for chromosomal abnormalities and fetal structural abnormalities. The fundamental requirement for any obstetrician who intends to handle subjects with recurrent spontaneous miscarriages is to know how to diagnose a miscarriage on ultrasonography (USG). This chapter covers the gestational sac features, subchorionic hemorrhage, fetal cardiac activity, yolk sac, and Doppler findings. The yolk sac forms by 28 menstrual days and is the first structure visible in the GS.
