High-risk pregnancies require an exhaustive follow during the entire gestation period, both medical, analytical and ultrasound. In some cases they require the collaboration of other specialists such as endocrinologists, cardiologists, intensivists, etc.
the analytical and other initial complementary explorations will be basically the same as the control of a low risk pregnancy. Outside of this line, we will ask for those tests that help us to control the pathology of each patient (electrocardiogram, echocardiography in cardiac pathology, serological markers in viral infections, etc.).
ultrasounds, in this type of pregnancy, are more frequent and in many cases are accompanied by specific explorations such as the Doppler study, which allows to evaluate the blood supply of the fetal and placental vessels.
Lately, 4D ultrasound has been incorporated to visualize, in real time, the fetal morphology in three dimensions, providing great information in the case of some fetal malformations.
