The role of ultrasound in the expectant management of early pregnancy loss

Objective To define the sonographic criteria which best determine the likel ihood of successful expectant management of early pregnancy failure (EPF). Methods Women with an ultrasound diagnosis of EPF at 7- 14 weeks' gestation were offered the option of expectant management or surgical evacuation. Results Five hundred and forty-five women had a diagnosis of EPF; 298 with incomplete miscarriage and 247 with missed miscarriage or anembryonic pregn ancy. A total of 305 women opted for expectant management, with an overall success rate of 86%. The success rate for incomplete miscarriage (96%) was significantly better than that for missed miscarriage (62%). Conclusion This study demonstrates that EPF can be safely managed expectant ly. Ultrasound has an invaluable role in predicting the likelihood of succe ssful expectant management enabling patients to make an informed choice abo ut their medical cure.
