[A case of partial anomalous pulmonary venous return to inferior vena cava and left atrium (Scimitar syndrome)].

Scimitar syndrome is relatively uncommon syndrome. A 14-year-old female referred to our hospital for abnormal shadow of chest fluoroscopic examination. She had no symptom except cough due to bronchial asthma. Chest X-ray film showed Scimitar sign. Cardiac catheterization revealed 30% left to right shunt without atrial septal defect. Pulmonary angiography showed anomalous pulmonary vein was drained to inferior vena cava and left atrium. Surgical correction was attempted monitoring the pulmonary arterial pressure. Anomalous pulmonary vein and systemic arteries were ligated and divided at the level of diaphragm. Postoperative course was smooth. We have found 4 similar operated cases previously reported in the world.
