Management of Cesarean Scar Pregnancy: A Single-Institution Retrospective Review

Figure 1

Flow chart of patients: class risk, treatment modality, and postoperative complications. According to ultrasound findings that focused on myometrial thickness and presence of a vascular pattern of the cesarean section scar, we stratified patients into tree risk classes: class 1: myometrial thickness ≤ 2 and high vascular pattern; class 2: myometrial thickness > 2 and high vascular pattern; class 3: myometrial thickness > 2 and normal vascular pattern. W: weeks of gestation at diagnosis; UAE: uterine artery embolization; D&S: dilatation and suction; MTX ii: methotrexate intramuscular injection; HSC: hysteroscopic resection; EM: Expectant Management; Surg: surgery (laparotomic edge excision or hysterectomy).
