Color Doppler Examination in the First Trimester
Blood flow measurements are performed as part of the ETS and PES. The ductus venosus, the flow over the heart valves between the atrium and chamber in the heart of the child and the maternal vessels are examined. The early Doppler examination of multiple pregnancies, especially monochorial multiple births, is very important here, since there can be a high risk potential here.

Color Doppler Examination
With the Colour Doppler Examination, we can dynamically represent and interpret the blood flow and vascular resistance in the child’s arteries and veins and the supply to the placenta. Physiological care (unremarkable) provides very characteristic frequency patterns, as well as pathological (noticeable) conditions, so that the resulting risks can be identified very early, sometimes in the first trimester of pregnancy, prospectively for the further course of the pregnancy. Continuous monitoring and intervention are ideally possible.
Mother and child health are top priorities.
Indications for this Doppler examination result from certain risks for the course of pregnancy, e.g.:
- maternal disease,
- abnormalities in the growth of the fetus (SGA, LGA, IUGR, PE, SIH, HELLP),
- multiple pregnancies (FFTS, sIUGR),
- suspected heart defects or other malformations of the child,
- suspected chromosome disorder or syndromic disease,
- gestational diabetes (conspicuous OGTT, glucose load test),
- blood group or rhesus intolerance,
- maternal antibodies,
- infections (e.g. rubella, cytomegalovirus, parvovirus, toxoplasmosis etc.),
- premature or deficient births,
- changes in the amount of amniotic fluit,
- abnormalities in placental morphology.
- Echocardiography
