Three-dimensional power Doppler ultrasound diagnosis and conservative treatment of ectopic pregnancy in a cesarean section scar

Objective: To describe three-dimensional ultrasonographic features of an ectopic pregnancy in a cesarean scar. Design: Description of a case. Setting: Case report of one patient. Patient(s): A 38-year-old women with three previous cesarean deliveries. Intervention(s): Three-dimensional ultrasonography was performed for diagnosis and treatment. Main Outcome Measure(s): Local administration of methotrexate under ultrasonographic guidance. Result(s): Ultrasonographic study revealed a gestational sac in the anterior wall of the uterine isthmus with peritrophoblastic flow. It was treated conservatively and successfully with local methotrexate administration under ultrasonographic guidance. Conclusion(s): The early diagnosis of ectopic cesarean scar pregnancy allows the conservative treatment with local administration of methotrexate under ultrasonographic guidance.
