title: [Clinical analysis of lower uterine segment pregnancy with heavy hemorrhage in inducing abortion].
abstract: OBJECTIVE
  To discuss the diagnosis and conservation managements for the lower uterine segment pregnancy complicating the first trimester inducing abortion cases.
  
  
  METHODS
  Four cases of lower uterine segment pregnancy that had heavy hemorrhage and received bilateral uterine artery embolization (UAE) were analysed.
  
  
  RESULTS
  Four patients with previous caesarean section had torrential hemorrhage when they received inducing abortion in the first trimester. Digital subtractive angiography (DSA) showed branches of uterine artery were bleeding, the site of the branches were equivalent to the lower segment of uterus. UAE could control heavy uterine bleeding satisfactory and save their uterus successfully. One of four patients asked hysterectomy after UAE, her pathological examination of the operative specimen confirmed "lower uterine segment pregnancy with placenta increta".
  
  
  CONCLUSIONS
  Previous caesarean section is one risk factor of lower uterine segment pregnancy, UAE is one of the best satisfactory conservation managements; the main prevent methods are controlling caesarean section rate and paying attention to the contraception.
