Selective embryo reduction in a heterotopic pregnancy using potassium chloride injection resulting in a hematosalpinx

Objective: To incorporate conservative management of a heterotopic pregnancy using injection of KCl into the ectopic pregnancy (EP). Design: A retrospective case report. Setting: A patient referred to an academic institution in the division of Reproductive Endocrinology, Department of Obstetrics and Gynecology, incorporating the ultrasound (US) and operating room facilities. Intervention(s): Using US as a guide, KCl was injected into the chorionic cavity of an EP. Main Outcome Measure(s): Resolution of ectopic gestational tissue with resultant hematosalpinx requiring exploratory laparotomy. Uncomplicated prenatal course of intrauterine pregnancy. Result(s): Injection of KCl into the chorionic cavity of EP resulting in resolution of gestational tissue but complicated by hematosalpinx in the fallopian tube. Conclusion(s): Selective embryo reduction of a tubal heterotopic pregnancy remains a viable therapeutic option.
