title: Heterotopic triplets: tubal ectopic and twin intrauterine pregnancy. A review of obstetric outcomes with a case report.
abstract: BACKGROUND
  Heterotopic triplets hardly take place, but nowadays the extended use of assisted reproductive technologies is increasing the ectopic pregnancies rate and subsequently the heterotopic pregnancies, leading to a potentially dangerous condition for the woman and the intrauterine pregnancy.
  
  
  METHODS
  Fourteen cases previously reported in the literature of patients presenting an intrauterine twin pregnancy which became complicated by a tubal ectopic pregnancy have been reviewed. The case of a patient following a homologous intrauterine insemination treatment, resulting in live birth of both twins, is also described.
  
  
  CONCLUSIONS
  Although the diagnosis of heterotopic triplets with tubal ectopic is challenging, a timely surgical treatment will preserve intrauterine gestation with a great chance of a successful obstetric outcome for both twins.
