title: [Sonography with color and pulsed Doppler in fetal pulmonary malformations].
abstract: OBJECTIVE
  Evaluate the advantages of color Doppler and pulsed Doppler in the diagnosis and prognosis of fetal pulmonary malformations.
  
  
  METHODS
  This retrospective study of 24 fetuses explored pulmonary malformations using sonography. A classification into four groups was made based on the presence of cysts and the echogenicity of the lesion, then analysis of video recordings including Doppler with an interpretation chart: afferent vessel, color chart, spectrum shape (afferent vessel and within the malformation) to determine the contribution of Doppler within each group.
  
  
  RESULTS
  Four lesions were avascular: bronchogenic cysts (three cases), subphrenic sequestration (one case). The other lesions were vascularized and color Doppler determined the source of vascularization feeding the malformation: branches of the pulmonary artery in 13 cases (eight cases of cystic adenomatoid disease, two cases of atresia, and three airway obstacles) or the aorta in seven cases (pulmonary sequestrations) with pulmonary venous return, six cases (intralobular sequestrations), or systemic venous return, one case (extralobular sequestration). The pulsed Doppler recording in the malformation (six cases) completed the color Doppler examination by showing the different spectrum shapes according to the aortic or pulmonary source of flow. The color chart matched in three cases (normal pulmonary segmentation) and was heterogeneous in eight cases (parenchymatous dysplasia). Furthermore, perfusion intensity was correlated with lesion progression.
  
  
  CONCLUSIONS
  Color Doppler and pulsed Doppler provided a more precise diagnosis of these malformations and seems to contribute prognostic information.
