Scorurile Z şi provocări în diagnosticul coarctaţiei aortice fetale.

Introduction. Fetal aortic coarctation still represents a challenge even for the best sonographers, especially in the early forms of appearence. Case presentation. A secundipara, with a previous healthy child, presents for the first assesement with a 32-week pregnancy. The ecography showed: IUGR of minus 3 weeks, a significant discrepancy between the right and left ventricule, fibroelastosis of the wall in right ventricule, and a suspicion of aortic coarctation. The aortic isthmal diameter was measured immediately proximal to the insertion of the arterial duct in the transverse (three vessel and trachea) and sagittal view, and the ductal diameter was measured immediately before it entered the descending aorta in the same view. Conclusions. The Z-scores for the fetal aortic isthmus and arterial duct are measured in the three vessels and trachea view and for the isthmus in the sagittal plane. In suspected coarctation, these Z-scores and the isthmal to ductal ratio may help in longitudinal assessment of the aortic arch and help at the prenatal diagnosis of coarctation.
