[Intraluminal dilation of inferior vena cava stenosis after repair of the scimitar syndrome in an adult patient].

A 39 year-old woman diagnosed with anomalous drainage of middle and lower right pulmonary veins to the inferior vena cava was corrected surgically by means of baffle with patch up to the left atrium. Early after the operation the patient related intolerance to small efforts and an episode of syncope. The cardiac catheterization demonstrated the presence of a severe stenosis in the inferior vena cava, in its union with the right atrium, that was successfully treated by means of intraluminal percutaneous dilation with a catheter of Inoue. After the procedure the gradient decreased and she improved tolerance to effort, which persisted 10 months later.
