ABSTRACT
Diabetics Mellitus complications approximalety 3-4 per 1000 pregnancies. It is a syndrome in which hereditasry and environmental factors intersect leading to inadequate insulin action. In this stud we assess fetal lung in family diabetic pregnant women through studding fetal lung circulation by means of pulmonary Doppler investigation, determining fetal lung volume and detection of other malformation if present by using 3D U/S. This study included 60 pregnant women [in the second half of pregnancy] who attended the high risk pregnancy clinic at El Galaa Teaching Hospital. They were classified into two group, group I [control] 20 cases and group II [test group] 40 cases subdivided group II A 20 cases with controlled diabetes and group II B 20 cases with uncontrolled diabetes. All were subjected to color Doppler investigation, 3D U/S and genetic pedigree analysis to select familiar diabetic and interpretation of the results as regards pulmonary circulation, lung volume, birth weight and outcome of pregnancy showed that Diabetes Mellitus wither controlled or not does not significantly alter the fetal pulmonary artery waveforms or fetal lung volume assessed by 3D U/S at does not affect either the fetal lung vasculature or fetal lung mass. However further studies are needed to assess the role of these recent diagnostic tools in evaluating fetal lung maturity
