Abstract
Pregnant women are at an increased risk of a number of conditions that are associated with bleeding. Conditions such as ectopic pregnancy, retained products of conception, placenta previa, abruptio placentae, morbid adhesion of the placenta, and postpartum hemorrhage can be associated with massive bleeding that endangers the maternal life and health. Screening, early detection, and prevention play a key role in reducing maternal morbidity and mortality caused by these conditions. Ultrasound, in experienced hands, is an effective tool that can assist in diagnosing many of these obstetrical conditions. The advances in technology and the non-invasive nature of ultrasound examination have made it popular in our daily obstetrical practice. The review discusses the role of ultrasound in the most common life-threatening conditions during pregnancy.
