[Abstract]Objective To understand the risk of heterotopic pregnancy when intrauterine pregnancy and abdominal pain co-exist. Methods and resultsWe report a patient with heterotopic pregnancy in a naturally occurring pregnancy; she also had high risks for secondary infertility. At gestational week 13 she had hemorrhagic shock due to intrauterine pregnancy complicated with rupture of tubal pregnancy; salpingectomy was performed via open operation. The intrauterine pregnancy was uneventful after operation, and a healthy baby was delivered through cesarean section at 37+2 weeks due to placental previa. MethodsHeterotopic pregnancy usually occurs in women receiving assisted reproductive technology, but it can also happen in natural conception when there are high risk factors. Satisfactory outcome can be obtained in patients with heterotopic pregnancy, rupture of tubal pregnancy, and hemorrhagic shock, if prompt measures and supporting treatment can be given.
