[Lung hypoplasia and the application of Doppler ultrasonography in the assessment of fetal pulmonary circulation].

The paper presents a review of literature concerning the use of Doppler technique in the evaluation of pulmonary blood flow. Especially, it is important to monitor the development of lung in suspicion of lung hypoplasia that closely correlates with abnormal development of pulmonary vessels. In the literature there are single reports pointing on its usefulness in the detection of lethal lung hypoplasia. It has been suggested that this technique may provide valuable information of the development of vascular bed in lung. Recent data concerning Doppler blood flow velocimetry in hypoplastic lung stimulate to further studies suggesting their significant value in the diagnosis and distinguishing the lethal form of pulmonary hypoplasia.
