Evaluation of routine early pregnancy ultrasonography

ABSTRACT

Study of 750 pregnant woman who were subjected to routine early pregnancy sonography scan is presented. The ultrasonic scan calculated accurately [to within + 14 days] the date of delivery in about 90% of women who were unsure of their dates. Clinical estimation of gestational age compared well with ultrasonic calculation in singleton pregnancies. Sonography diagnosed all the lethal congenital anomalies met with in the early pregnancy sonography scan. The early pregnancy scan proved of value for the women who are uncertain of their last menstrual period and for those with known early pregnancy risks as well. Optimal information is obtained when the procedure is done between the 14th and 18th weeks of gestation
