An ectopic pregnancy occurs when a fertilised ovum implants outside the normal uterine cavity and can cause of morbidity and occasionally mortality in women of reproductive age. The diagnosis relies on a combination of ultrasound scanning and serial serum beta-human chorionic gonadotropin. Ectopic pregnancy is one of the few medical conditions that can be managed expectantly, medically or surgically.
Incidence is 1-2% of population.Three main contributing factors are Smoking, PID and ART. Ectopic pregnancy remains the leading cause of pregnancy-related first trimester death (0.35/1000 ectopic pregnancies).
