Abstract:

Rudimentary horn pregnancy (RHP) is a rare type of ectopic pregnancy, which is prone to serious consequences such as uterine rupture. In this article, we analyzed a case of RHP and discussed the expectant treatment management strategy and the timing of termination of pregnancy. The patient was admitted to the hospital with irregular lower abdominal pain for 1 day at 27⁺⁴ weeks of gestation, and was diagnosed with RHP by ultrasound. The patient refused to undergo surgery, and was given symptomatic treatments such as suppression of uterine contractions under close observation. At 30⁺¹ weeks of gestation, a live baby was delivered by cesarean section due to frequent uterine contractions. Therefore, with a clear diagnosis, good monitoring conditions, and adequate surgical preparation, RHP can be considered expectant treatment to obtain as many surviving newborns as possible.
