Inferior vena cava stenosis in scimitar syndrome: a case report.

The scimitar syndrome, first described by Chassinat in 1836, consists aessentially of an anomalous pulmonary vein draining whole or part of the right lung into the inferior vena cava. Associated anomalies are frequent, such as hypoplasia of the right lung, dextrocardia, malformations of the right pulmonary artery and bronchial tree, and abnormal arterial supply of the right lung (the so-called sequestration). This article describes a scimitar syndrome associated with stenosis of the inferior vena cava, whose initial diagnosis was made by two-dimensional echocardiographic Doppler color flow mapping. To our knowledge this is the first description of such an unusual association.
