Abstract:

Objective To explore the predictive value of average diameter of fetal sac on the massive hemorrhage during the curettage of cesarean scar pregnancy (CSP). Methods The data of 117 CSP patients treated with curettage in Tianjin Hospital were collected. Patients were divided into the two groups, the massive hemorrhage group (n=27) and the no-massive hemorrhage group (n=90). The maximum diameter of fetal sac, the average diameter of fetal sac, the thickness of the lower segment of the anterior wall of uterus, the type of fetal sac insertion, the direction of fetal sac growth, the growth of fetal bud, the growth of fetal heart, the type of focus, the lower segment of the anterior wall of uterus protrusion, the color Doppler blood flow signal classification of the focus, patient age and preoperative human chorionic gonadotropin (HCG) were compared between the two groups. The predictive ability of the average diameter of fetal sac to the massive hemorrhage in CSP curettage was explored. Results The results of single factor Logistic regression analysis showed that the maximum diameter of the fetal sac (OR=1.281, 95%CI: 1.020-1.608), the average diameter of the fetal sac (OR=1.611, 95%CI: 1.112-2.332), the thickness of the lower segment of the anterior wall of the uterus (OR=0.026, 95%CI: 0.001-0.914) and the protrusion of the lower segment of the anterior wall of the uterus (OR=3.081, 95%CI: 1.262-7.521) were the influencing factors of severe hemorrhage in CSP curettage. Stepwise Logistic regression analysis showed that the average diameter of fetal sac was an independent risk factor for massive hemorrhage during CSP curettage (OR=1.611, 95%CI: 1.112-2.331), and the predicted area under the curve (AUC) of the increase of the average diameter of fetal sac for massive hemorrhage after CSP curettage was 0.660 (95%CI: 0.548-0.773). Conclusion The average diameter of fetal sac can increase the prediction ability of massive hemorrhage after CSP curettage.
