title: Six cases of tubal stump pregnancy: complication of assisted reproductive technology?
abstract: OBJECTIVE
  To present six cases of tubal stump pregnancy and discuss possible etiologies.
  
  
  METHODS
  Case series.
  
  
  METHODS
  Department of Obstetrics and Gynecology at a tertiary referring medical center.
  
  
  METHODS
  Six women with tubal stump pregnancy diagnosed and treated in the department from 2004 to 2010 according to electronic files and histological reports.
  
  
  METHODS
  None.
  
  
  METHODS
  Assisted reproductive technology (ART) before tubal stump pregnancies.
  
  
  RESULTS
  From 2004 to 2010, this study diagnosed six tubal stump pregnancies among 1,466 ectopic pregnancies, an incidence of 0.4%. Of the six cases, two conceived spontaneously after ovulation induction. Four of them conceived after IVF-ET programs.
  
  
  CONCLUSIONS
  Tubal stump pregnancies may be one of the complications of ART. In view of the risk of early rupture in a tubal stump pregnancy, early diagnosis is warranted to avoid maternal morbidity.
