Scar pregnancy: a rare complication of caesarean section

In this paper, we report a rare type of ectopic pregnancy implanted in a previous caesarean scar. Scar pregnancy was diagnosed at six weeks gestation in a woman with three prior caesarean deliveries. Management with the usual dose of Methotrexate was unsuccessful. The patient continued to have pelvic pain, the beta human chorionic gonadotropin (ßhCG) increased and there was persistent foetal cardiac activity. Subsequently, dilatation and curettage was performed under ultrasound guidance without complications. We conclude that scar pregnancy presents a diagnostic and therapeutic challenge to the clinician and the optimal management strategy needs to be explored.
