Background:
Cesarean scar pregnancy (CSP), a rare iatrogenic form of ectopic pregnancy (EP), cause of severe maternal morbidity. Each subtype of CSP needs different treatment and there is no consensus about this topic. Despite improvements, the lack of universally accepted therapeutic management and discordance present in literature indicates that treatment has been mainly based on experiences reported.
Methods:
A case series of our double combined approach with methotrexate (MTX) administration followed by vacuum aspiration or resectoscopic approach was reported, with an overview of literature. Eleven patients with CSP underwent a double-step treatment: systemic MTX therapy followed by vacuum aspiration or by resectoscopy, if the gestational sac was embedded deeply in myometrium. For CSP type 1, according to Delphi sonographic classification, with minor potentially risk of complications with a myometrial thickness >3.5 mm, we preferred to adopt vacuum aspiration, while type 2-3 of CSP and myometrial thickness ≤3.5mm were managed with resectoscopy.
Results:
The average gestational age was 59.1±7.22 days. On the seventh day after MTX administration, the serum β hCG levels decreased in 80% of all patients. After the MTX injection, the CSP mass did not disappear in any patient. MTX therapy was followed by vacuum aspiration in six and by resectoscopy in five cases. In one case bleeding was controlled by Foley balloon treated with vacuum. In type II-III, CSP was performed UAE (uterine artery embolization) followed by resectoscopy procedure.
Conclusions:
Compared with the results in previous studies, MTX administration followed by suction curettage was more effective than dilatation and curettage and systemic MTX in treatment of CSP. We consider very useful this procedure in case of slow absorption and when the camera was embedded deeply in myometrium (CSP2-3), because that hysteroscopy evaluation of uterine cavity under direct vision is highly accurate in identifying the real cleavage of the gestational camera. We have only used vacuum aspiration in CSP type 1 for minor risk of bleeding.
