Uterine anomalies and failed surgical termination of pregnancy: the role of routine preoperative transvaginal sonography.

Abstract

Although used extensively in the assessment of many gynecological conditions, transvaginal ultrasonography is not performed routinely prior to termination of pregnancy in the UK. We describe a case in which surgical evacuation of the uterus failed. Postoperatively, transvaginal ultrasonography demonstrated a bicornuate uterus with a viable pregnancy within the left horn. Subsequent medical termination of pregnancy was successful. This case shows the potential value of transvaginal ultrasonography prior to termination of pregnancy. A prospective trial is needed to assess whether its routine introduction into clinical practice will lead to a reduction in morbidity resulting from termination.
