Fetal and Neonatal Middle Cerebral Artery Hemodynamic Changes and Significance under Ultrasound Detection in Hypertensive Disorder Complicating Pregnancy Patients with Different Severities

Figure 3

Blood flow spectra of fetal UA measured by transabdominal ultrasound. (a) Doppler waveform of UA blood flow in the normal group. (b) Doppler waveform of abnormal UA blood flow in the mild group. Diastolic blood flow signal of UA disappeared. (c) Doppler waveform of abnormal UA blood flow in the severe group. The UA diastolic blood flow signal was reversed.
