Ectopic pregnancy - any pregnancy outside the uterine cavity - affects 1-2 % of all pregnancies. While the diagnosis and treatment of the most common ectopic pregnancy (tubal pregnancy which accounts for > 90 % of cases) is established, other forms, such as Caesarean scar pregnancy, pose an increasing challenge. This article describes the different forms of ectopic pregnancies and the respective therapeutic options.
