Risk factors for the formation of aberrant artery collaterals in the uterus with scar in pregnancy womenunderwent cesarean / 中南大学学报(医学版)

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.
@*CONCLUSION@#Aberrant artery collaterals were more frequent in patients with pelvic inflammatory disease, pregnancy complications, abortions and uterine fibroids or adenomyosis.
