Abstract:
Objective:To investigate the risk factors of postpartum embryo residues associated with uterine arteriovenous fistula.Methods:From January 2000 to December 2020, 26 cases of postpartum embryo residue complicated with uterine arteriovenous fistula in Tangshan Maternal and Child Health Hospital were selected as the case group, and 32 cases of postpartum embryo residue without uterine arteriovenous fistula were selected as control group.Both the case group and the control group had embryo residue in cesarean scar.Univariate and multivariate logistic analysis were used to screen the risk factors of postpartum embryo residue combined with uterine arteriovenous fistula.Results:There were 26 patients in the case group, including 3 patients after medical abortion, 17 patients after artificial abortion, 2 patients after cesarean section, and 4 patients after mid-term induced labor.There were 32 patients in the control group, including 7 patients after medical abortion, 11 patients after induced abortion, 8 patients after cesarean section, and 6 patients after mid-term induced labor.There were 11 patients in the case group and 3 patients in the control group.Univariate analysis showed that: the occurrence of postpartum embryo residue combined with uterine arteriovenous fistula was related to the time of vaginal bleeding, HCG value before and after treatment, hemoglobin value before treatment, platelet count and residual embryo area(all P<0.05). Multivariate regression analysis showed that the increase of hCG before treatment ( OR 20.319, 95% CI 1.348-306.187) and the decrease of hemoglobin before treatment ( OR 0.870, 95% CI 0.788-0.960) were the independent risk factors of postpartum embryo residue combined with uterine arteriovenous fistula (all P<0.05). Conclusion:The risk factors of uterine arteriovenous fistula in postpartum embryo residue patients with elevated hCG value and decreased hemoglobin value before treatment should be highly vigilant to reduce the rate of clinical missed diagnosis.
