title: [Risk factors for the formation of aberrant artery collaterals in the uterus with scar in pregnancy womenunderwent cesarean].
abstract: OBJECTIVE
  To evaluate the prevalence and risk factors for the formation of aberrant artery collaterals in the uterus during uterine artery embolization (UAE).
  
  
  METHODS
  The data of 144 women with scar in the uterus due to cesarean were retrospectively analyzed. They underwent UAE in the period of 2009-2014 and were divided into two groups according to a standard with or without the aberrant artery collaterals in the uterus. The risk factors were analyzed.
  
  
  RESULTS
  Aberrant artery collaterals were found in thirty-four patients. According to multiple logistic regression analysis, the presence of placenta previa (RR=78.556, 95% CI: 2.869-2 150.651, P=0.010), pelvic inflammatory disease (RR=6.633, 95% CI: 1.595-27.592, P=0.009), pregnancy complications (RR=7.264, 95% CI: 1.622-32.531, P=0.010), abortions (RR=18.381, 95% CI: 1.683-200.752, P=0.017) and uterine fibroids or adenomyosis (RR=12.580, 95% CI: 1.004-157.550, P=0.050) were the factors for the presence of aberrant artery collaterals.
  
  
  CONCLUSIONS
  Aberrant artery collaterals were more frequent in patients with pelvic inflammatory disease, pregnancy complications, abortions and uterine fibroids or adenomyosis.
