Early detection of pathologic pregnancy by transvaginal sonography

Abstract

Vaginal ultrasonography, by virtue of its excellent resolution, has resulted in changing our concepts about early pregnancy both in normal and abnormal gestations. The purpose of this report is to examine the clinical application of this technique in abnormal early pregnancy. Pathologic pregnancy ultimately will prove to be either (1) an ectopic pregnancy or (2) an intrauterine gestation that may be destined to failure. (A third group, fetuses with anomalies, will be dealt with elsewhere). Vaginal sonography has enhanced very early pathologic diagnosis in pregnancy because of its ability to image things previously not seen with such clarity, and because the scanning process can be carried out at the time of pelvic examination when the clinical indication is first encountered.
