Effectiveness and safety of ultrasound-guided intramuscular lauromacrogol injection combined with hysteroscopy in cervical pregnancy treatment: A case report.

BACKGROUND

Cervical pregnancy is increasing in morbidity, and a definite diagnosis in early stages is challenging due to its specific onset site. Surgery is the mainstay of treatment for cervical pregnancy, but it may result in the loss of natural fertility. Therefore, it is a great challenge to pursue a safe and effective treatment for cervical pregnancy.

CASE SUMMARY

We report the case of a cervical pregnancy successfully treated by ultrasound-guided cervical-intramuscular lauromacrogol injection combined with hysteroscopy. A 23-year-old woman with minor irregular vaginal bleeding was admitted to our department with suspected ectopic pregnancy. Transvaginal ultrasound revealed a gestational sac (approximately 22 mm x 13 mm) situated in the cervical canal with a yolk sac and blood flow signals. No cardiac activity was detected. Serum beta progesterone was 17.06 ng/mL, and serum beta human chorionic gonadotropin (β-HCG) was 5077.0 IU/L. The patient was diagnosed with cervical pregnancy. She was treated by ultrasound-guided cervical-intramuscular injections of lauromacrogol (3 mL) in combination with aborting under hysteroscopic visualization. A gradual decrease in β-HCG levels and normal ultrasound findings were observed. Postoperative pathologic examination showed the presence of villi and changes in the endometrium in the secretory phase. The patient was discharged on day 6, and her β-HCG level was 0.67 mIU/mL after 1 wk. There was no statistical difference between baseline and 1-week postoperative data in terms of serum indices including liver function, renal function, and routine blood analysis after treatment. The patient subsequently became pregnant 2 mo later and no abnormalities were detected on routine screening during pregnancy.

CONCLUSION

Ultrasound-guided cervical-intramuscular lauromacrogol injection combined with hysteroscopy may be effective and safe in the treatment of cervical pregnancy.
