An ectopic pregnancy is an early pregnancy that occurs outside of the normal location (uterine lining) for a developing pregnancy. The vast majority of ectopic pregnancies are so-called tubal pregnancies and occur in the Fallopian tube. An ectopic pregnancy occurs in about one in 1%-2% of all pregnancies.
These other places can be:
1) Fallopian tubes
4) Cornua of uterus
5) Abdominal Cavity
The major health risk of ectopic pregnancy is rupture leading to internal bleeding. Before the 19th century, the mortality rate (death rate) from ectopic pregnancies exceeded 50%. Statistics suggest that with current advances in early detection, the mortality rate has improved to less than five in 10,000. The survival rate from ectopic pregnancies is improving even though the incidence of ectopic pregnancies is also increasing. The major reason for a poor outcome is failure to seek early medical attention. Ectopic pregnancy remains the leading cause of pregnancy-related death in the first trimester of pregnancy.
