Mandatory medical device diagnostics in gravidity (pregnancy).
- Vaginal sonography (ultrasound examination using an ultrasound probe inserted into the vagina) or abdominal sonography* (every 4 weeks) [hydrops fetalis? – Disease of the fetus with increased edema (fluid accumulation) in the fetal soft tissues and serous body cavities].
- Fetal ultrasound diagnostics (malformation diagnostics).
- Doppler sonography to determine the blood flow pattern in the uterine arteries as well as the fetal blood flows in arteries and veins* [determination of the systolic blood flow maximum velocity in the cerebral artery (Vmax > 1.5 MoM); impending placental insufficiency (lack of function of the placenta) can thus already be detected in the 20th week of pregnancy (SSW). signs of cardiac insufficiency/heart failure (including pericardial effusion/pericardial effusion, pathological Doppler sonographic blood flow values, arrhythmia/cardiac arrhythmia)]. (Examination: weekly from the 20th SSW)Note: In maternal B19V infection, fetal anemia (fetal anemia) may develop with a time delay of 2-8 weeks.
- Fetal echocardiography (echo) – to rule out tricuspid regurgitation (leakage of the tricuspid valve of the heart).
Optional medical device diagnostics – depending on the results of the history, physical examination, laboratory diagnostics and obligatory medical device diagnostics – for differential diagnostic clarification.
- Abdominal ultrasonography (ultrasound examination of the abdominal organs) – if liver involvement is suspected.
* Fetal anemia diagnostics (diagnostics to detect infantile anemia).
