title: Cervical heterotopic pregnancy after assisted reproductive technology successfully treated with only simple embryo aspiration: a case report.
abstract: BACKGROUND
  The etiology of cervical heterotopic pregnancy is unknown, but most are associated with assisted reproductive techniques. Various types of conservative management to save the intrauterine pregnancy have been attempted.
  
  
  METHODS
  A 35-year-old woman conceived after in vitro fertilization/embryo transfer for primary malefactor infertility. At 7(3/7) weeks of gestation, only the embryo was aspirated without fluid. Delivery of a healthy infant at 35 weeks was successful.
  
  
  CONCLUSIONS
  Simple embryo aspiration under transvaginal ultrasonography guidance can be used in cervical heterotopic pregnancy.
