Methotrexate therapy followed by suction curettage followed by Foley tamponade for caesarean scar pregnancy

Objectives: Caesarean scar pregnancy (CSP) is a very rare and dangerous form of pregnancy because of the increased risk of rupture and excessive hemorrhage. There is currently no consensus on the treatment. We studied if methotrexate (MTX) therapy followed by suction curettage followed by Foley tamponade was a viable treatment for patients with CSP. Study design: Forty-five patients with CSP in our hospital received a single dose of 50 mg/m(2) MTX by intramuscular injection. If gestational cardiac activity was seen on transvaginal ultrasound, local injection of MIX was given. After 7 days, suction curettage was performed to remove the retained products of conception and blood clot (CSP mass) under transabdominal sonography (TAS) guidance. After the suction curettage, a Foley catheter balloon was placed into the isthmic portion of cervix. Results: Forty-two subjects were successfully treated and 3 subjects failed treatment. The mean estimated blood loss of all 45 patients was 706.89 +/- 642.08 (100-3000) ml. The resolution time of the serum beta-hCG was 20.62 +/- 5.41 (9-33) days. The time to CSP mass disappearance was 12.57 +/- 4.37 (8-25) days. Conclusions: MIX administration followed by suction curettage followed by Foley tamponade was an effective treatment for caesarean scar pregnancy. (C) 2011 Elsevier Ireland Ltd. All rights reserved.
