Early cervical pregnancy: ultrasonic diagnosis and conservative treatment

Abstract

Five cases of cervical pregnancy collected over an 8-year period (1971--1978) are analyzed. The incidence of cervical pregnancy at this institution is 1:7040 pregnancies. All cases were diagnosed prior to 12 weeks' gestation, and conservative treatment was instituted in each case. Etiology, criteria, definition, and clinical and pathologic signs are discussed. Several unusual features are emphasized, particularly conservative treatment and the use of ultrasound as a diagnostic aid.
