Laparoscopic management of a twin pregnancy in a rudimentary uterine horn with preoperative methotrexate therapy: A case report

Abstract

  Pregnancy in the rudimentary horn is rare, with a reported incidence of 1 in 76,000-150,000. We report a case of a twin pregnancy in the rudimentary horn at 8 weeks of gestation. The patient was a 19-year-old nullipara. Before the surgery, she was administered methotrexate (MTX) and the serum hCG level was monitored. After we confirmed that the hCG level had decreased to within the normal range, and angio-CT imaged the absence of blood flow in the rudimentary horn, laparoscopic surgery was performed. The rudimentary horn was successfully excised with minimal bleeding. Laparoscopic surgery with preoperative MTX administration followed by minimally invasive surgery for pregnancy in the rudimentary horn is both safe and effective.
