RESUMEN
OBJECTIVE: To discuss the clinical significance of cesarean scar pregnancy with expectatant treatment.METHODS: Collect 21 cases of CSP between 2012 and 2017 in the Third Affiliated Hospital of Guangzhou Medical University.Group A had 8 cases who were pregnant again after intervention treatment,and group B had 13 cases who insisted on expecting treatment.We summarized clinical indexes of both groups,such as preserving uterus,bladder rupture,admission to ICU,blood transfusion,placenta implantation,etc. in order to further study the significance of expecting treatment for CSP.RESULTS: All of group A were pregnant again after intervention treatment,of whom 1 was CSP again and hysterectomy was performed at 15 weeks due to placenta implantation,while another 7 were uterine pregnancy,of whom 3 were term birth and had no placenta implantation,and another 4 were terminated in response to the requirements of patients,of whom 1 was treated with drug abortion and 3 underwent dilatation and curettage.Uterus was preserved in the 7 women,and there was no bladder rupture,no admission to ICU,no blood transfusion,and no placenta implantation.Among the 13 cases in group B, 6 cases underwent cesarean section during third trimester,including 3 cases of premature delivery and 3 cases of delivery at 37 weeks.5 cases were pregnant to second trimester,containing 4 cases received hysterectomy and 1 case suffered subtotal hysterectomy.2 cases were pregnant to first pregnancy, including 1 case of abdominal nidus resection, 1 case of ultrasound-guided dilation and curettage;Among the13 patients, 4 cases underwent bladder rupture, 4 cases lost uterus, 5 cases were admitted to the ICU, and 10 cases required blood transfusion.Placental implantation occurred in 11 cases who were pregnant to second and third trimester.CONCLUSION: Most of CSP with expecting treatment will develop into placenta implantation inevitably in the late stage of pregnancy.The patients with CSP can be pregnant again after early intervention and have extremely low possibility of a second CSP.
