[Abnormal pulmonary venous return from the right lung into the inferior vena cava or scimitar syndrome. 2 cases: hemodynamic study and surgical correction].

Two cases of abnormal venous return from the right lung into the inferior vena cava, or the scimitar syndrome, have been studied. The essential features of this condition are given, emphasis being laid on the haemodynamic findings. Surgical correction of the abnormal pulmonary venous return seems to be a logical solution when the left-right shunt is of significant size.
