While some complications improve or are fully resolved after pregnancy, some may lead to lasting effects, morbidity, or in the most severe cases, maternal or fetal mortality. [1] [2] [3] Common complications of pregnancy include anemia, gestational diabetes, infections, gestational hypertension and pre-eclampsia.
GTN often arises after molar pregnancies but can also occur after any gestation including miscarriages and term pregnancies. [6] Although risk factors may impact on the development of the tumor, most do not directly cause of disease. According to some studies, the risk of complete molar pregnancy is highest in women over age 35 and younger than 20.
