Abstract

Aim: Cesarean scar pregnancy (CSP) is a rare type of ectopic pregnancy. The gestational sac is implanted in the myometrium at the site of a previous cesarean section. Mothers with CSP are faced with risks of unpredictable massive bleeding or more fatal complications. The purpose of this retrospective study was to assess the feasibility, efficacy, and reliability of the intraoperative ultrasound-guided vacuum aspiration method as an effective treatment option for CSP.

Methods: We undertook a retrospective analysis of CSP patients who had undergone the vacuum aspiration method, by reviewing patient records from the period October 2015 to January 2018. All of the operations were carried out under general anesthesia, with patients in the lithotomy position, using suprapubic ultrasonography guidance. A vacuum aspirator was used to aspirate the whole pregnancy material without perforating the previous cesarean section scar.

Results: Ten women with CSP were managed successfully by ultrasound-guided vacuum extraction without complications or further interventions, such as reoperation or methotrexate administration. Three of the 10 patients needed uterine Foley catheter tampon (50 cc) for 4 h after vacuum extraction alone was applied. During the study period, two additional patients who did not meet the criteria for the vacuum extraction method alone were managed with methotrexate plus vacuum application. Because of the rarity of the condition, the majority of CSPs are case reports or small case series reported in published works, with no consensus on the preferred course of treatment.

Conclusion: The vacuum extraction method seems to be a good and practical way of treating CSP. Comparisons of efficacy should be undertaken but large sample sizes are required. We hope this study brings a new perspective for larger sample-sized studies, considering the technique is feasible and applicable.
