Abstract
INTRODUCTION: Cervical ectopic pregnancy (CEP) is a rare but potentially life-threatening phenomenon, and conclusive management guidelines have not been elucidated. Patients undergoing assisted reproductive technologies (ART) are at increased risk of CEP and noninvasive, fertility-sparing treatments are necessary for this population. This case report demonstrates the safety and efficacy of a single dose of intramuscular methotrexate for CEP in early gestation. CASE DESCRIPTION: A 45-year-old patient (G3P0030) presenting with painless vaginal bleeding was found to have CEP on transvaginal ultrasound at 5 weeks and 1 day of gestation after undergoing day-5 frozen embryo transfer. She was given one 50 mg/m(2) dose of intramuscular methotrexate and she remained in a stable condition while being observed in the hospital. Her beta-hCG level decreased 38.2% between day 4 and day 7 after treatment and returned to nonpregnancy levels by day 28. DISCUSSION: A single dose of intramuscular methotrexate is an effective, noninvasive, fertility-sparing method of treatment for CEP in patients who are early in gestation and hemodynamically stable. This is a recommended option, especially for those undergoing fertility treatment. Further studies need to be performed to formulate national guidelines regarding the treatment of CEP.
