Background
This study aims to evaluate the curative effect and complications in cesarean scar pregnancy (CSP) patients treated with a transvaginal injection of absolute ethanol (AE) around the gestation sac (GS) under ultrasound guidance.
Methods
This retrospective clinical investigation analyzed 26 CSP patients treated at the Affiliated Hospital of Guilin Medical University in Guilin, Guangxi, China, between January 1, 2018 and January 30, 2019. Outcomes and complications were analyzed following treatment with AE.
Results
Out of the entire group, 20 patients were successfully treated with a single AE injection, while the remaining six patients required two or three repeat injections. In 21 patients, the serum beta-human chorionic gonadotropin (β-hCG) level was reduced to > 50% 1 day after a single AE injection; in 19 patients, the serum β-hCG level was reduced to > 80% 4 days after a single AE injection. In all patients, the average time for serum β-hCG to reduce to normal levels (< 3.0 mIU/mL) was 36.50 ± 12.54 days. The overall cure rate of CSP by AE injection was 100%. Average length of hospitalization was 6.73 ± 3.66 days, with Patient 2 having the longest hospitalization at 17 days, and Patient 3 the shortest at 2 days. No adverse effects on hematopoietic, hepatic or renal function were observed in the short term.
Conclusion
The study demonstrated that transvaginal injection of AE around the gestation sac under ultrasound guidance had good clinical effects, fewer complications, and merit as a novel treatment for CSP. However, larger multi-center trials are needed to confirm the safety and effectiveness of this treatment.
