Rare Case of Caesarean Scar Pregnancy with Soaring β-hCG Levels: A Therapeutic Challenge

Abstract

Caesarean Scar Pregnancy (CSP) is a life-threatening form of ectopic pregnancy characterised by abnormal implantation of embryo within the myometrium and fibrous tissues of a previous scar on the uterus. This is the case report of a 24-year-old pregnant lady who underwent previous caesarean section presented at eight weeks gestation with bleeding per-vaginum. Ultrasound of pelvis revealed an intrauterine gestational sac with a live foetus at the site of previous caesarean scar with very high levels of serum beta-human Chorionic Gonadotropin (β-hCG) of 88789 mIU/mL. To prevent surgical complications, a conservative approach was employed, involving injection methotrexate and uterine artery embolisation. Serial measurements of serum β-hCG and transvaginal sonography were used for monitoring. Treatment was successful and the β-hCG levels returned to normal on day 48. This case report highlights that conservative management is successful even with extremely high serum β-hCG levels, and an early recognition and timely intervention is the key to prevent poor outcomes.
