Suction Evacuation with Methotrexate as a Successful Treatment Modality for Caesarean Scar Pregnancies: Case series.

Pregnancy resulting from the implantation of an embryo within a scar of a previous Caesarean section is extremely rare. The diagnosis and treatment of Caesarean scar pregnancies (CSPs) are challenging and the optimal course of treatment is still to be determined. We report a case series of six patients with CSPs who presented to the Royal Hospital in Muscat, Oman, between October 2012 and April 2014. All of the patients were successfully treated with systemic methotrexate and five patients underwent suction evacuation either before or after the methotrexate administration. The patients were followed up for a period of 6-9 weeks after treatment and recovered completely without any significant complications. Suction evacuation with methotrexate can therefore be considered an effective treatment option with good maternal outcomes.
