Abstract

Cesarean section scar pregnancy is rare. A variety of interventions have been implemented to terminate the pregnancy and preserve the uterus; however, the optimal treatment is unknown. We describe two cases of this rare condition diagnosed by transvaginal ultrasound. In the first case the diagnosis of an 8-week non-viable gestation in a uterine scar was made sonographically in a 40-year-old woman. The patient was treated with intramuscular methotrexate. Myometrial integrity was suggested both by ultrasound findings and laparoscopic findings. In the second case, an early cervicoisthmic pregnancy in a uterine scar was diagnosed by sonography in a 39-year-old woman. This patient was treated successfully with a full course of intramuscular methotrexate. Complete disappearance of the gestational sac took place 4 months following beta-human chorionic gonadotrophin normalization. Intramuscular methotrexate may be a treatment alternative for Cesarean section scar pregnancies. Copyright © 2002 ISUOG
