Early Pregnancy Loss (EPL) is defined as a nonviable intrauterine pregnancy identified before 13 weeks gestation. ACOG states that ultrasound is the “preferred modality to verify the presence of a viable intrauterine gestation.” The AIUM Practice Parameter (see ‘Learn More – Primary Sources’ below) states
With transvaginal imaging, cardiac motion is usually observed when the embryo is 2 mm or greater in length. If an embryo less than 7 mm in length is seen without cardiac activity, a subsequent scan in 1 week is recommended to determine viability
Ultrasound Guidelines: The following criteria are derived from the 2012 Society of Radiologists in Ultrasound Multispecialty Panel on Early First Trimester Diagnosis of Miscarriage and Exclusion of a Viable Intrauterine Pregnancy
Early pregnancy loss may present with clinical symptoms such as cramping and bleeding. However, these findings can be present in normal, ectopic or molar pregnancies. Ultrasound, if available, is a critical diagnostic modality but must be used in combination with clinical and laboratory findings, particularly serum β-hCG. For more information on recommended management when pregnancy location cannot be confirmed, see ‘Related ObG Topics’ below.
