Caesarean scar pregnancy - Is there a light in the end of the tunnel?

Abstract

Purpose: to summarize and present a single tertiary center’s 25 years of experience managing patients with caesarean scar pregnancies and their long term reproductive and obstetric outcomes. Methods: A 25-year retrospective study included women diagnosed with CSP from 1996 to 2020 in one tertiary center. Data were retrieved from the medical records and through a telephone interview. Diagnosis was made by sonography and color Doppler. Treatments included methotrexate, suction curettage, hysteroscopy, embolization and wedge resection by laparoscopy or laparotomy as a function of the clinical manifestations, the physicians’ decisions, patient counseling, and parental requests. Results: Analysis of the records recovered 60 cases of CSP (two of whom were recurrent). All patients had complete resolution with no indication for hysterectomy. Thirty-five patients had a long-term follow-up, of whom 24 (68.6%) attempted to conceive again and 22 (91.6%) succeeded. There were 17/22 (77.3%) patients with at least one live birth, 3/22 (13.6%) spontaneous miscarriages and 2/22 (9%) recurrent CSP. The obstetric complications included abnormal placentation 5/19 (26.3%), premature rupture of membranes 2/19 (10.5%), preterm delivery 4/19 (21%) and abnormality of the uterine scar 2/19 (10.5%). There was one case of neonatal death due to complications of prematurity 1/19 (5.2%). Conclusion: CSP treatment focusing on reducing morbidity and preserving fertility has favorable long term reproductive and obstetric outcomes. In subsequent pregnancies, we recommend performing an early first trimester vaginal scan to map the location of the new pregnancy, followed by close monitoring given the obstetric complications mentioned above.
