Caesarean scar pregnancy: descriptive paper of three different types of management on a series of clinical cases.

Abstract

IntroductionA caesarean scar pregnancy is a complex iatrogenic pathology, which represents a consequence of a previous caesarean section. It increased in recent years due to parallel increase of cesarean sections.Material and methodsWe present a retrospective study on patients with caesarean scar pregnancy diagnosed in our department from June 2016 to June 2019. Stable women with an embryo (with or without cardiac activity) who accepted our experimental protocol were treated with single dose of methotrexate (50 mg administered locally intracavitary + 50 mg administered intramuscularly) and folinic acid (15 mg/day orally for 30 days). Clinically stable women with embryo (without cardiac activity) who decided to wait, were monitored by serial assays of b-hCG and clinical and ultrasonographic follow up. Women who were clinically unstable with embryo (without cardiac activity), were referred for urgent surgical treatment with dilation and curettage.ResultsCaesarean scar pregnancy was diagnosed in sixteen women. Among these women, seven were treated according to our experimental protocol with methotrexate and folinic acid and only one had profuse bleeding, which required a laparotomic hysterectomy. Four women were treated urgently with dilatation and curettage. Five women chose to wait: they were monitored and all spontaneously had a miscarriage.ConclusionsIn our preliminary study, we highlighted how our experimental protocol gave encouraging results in the first 10 weeks of caesarean scar pregnancy. However, caution is needed in patients with advanced gestational age, a gestational sac with large diameter, higher CRL and presence of embryonic cardiac activity.
