title: Successful management of a heterotopic Caesarean scar pregnancy: potassium chloride injection with preservation of the intrauterine gestation: case report.
abstract: Caesarean scar pregnancy (CSP), in which the pregnancy is located in the scar of a previous Caesarean section, is a rare situation that carries a high risk of uterine rupture. Improved ultrasound imaging allows early diagnosis of this condition, but there is no standard management. We report the first case of CSP associated with a normal intrauterine pregnancy. Potassium chloride administered under transvaginal ultrasonographic guidance terminated cardiac activity in the CSP. The CSP resolved, and a healthy infant was delivered at 36 weeks. When the diagnosis is early and the patient asymptomatic, surgery can be avoided, the CSP can be terminated selectively and the intrauterine pregnancy thereby preserved.
