MRI-based scoring model to predict massive hemorrhage during dilatation and curettage in patients with cesarean scar pregnancy

Cesarean scar pregnancy is a special type of ectopic pregnancy for which dilatation and curettage (D&C) is one of the main treatment modalities, and uncontrollable hemorrhage is a more dangerous complication during D&C. Accurate preoperative prediction of the risk of intraoperative hemorrhage will help gynecologists draw up precise treatment. The aim of this study is to develop an MRI scoring model for predicting intraoperative hemorrhage during D&C. The study found that cesarean section diverticulum area, uterine scar thickness and gestational sac diameter were independent risk factors for intraoperative hemorrhage. A scoring model was developed, The model possessed decent prediction performance.
