[Fontan completion after balloon angioplasty of multiple pulmonary artery stenosis in a child with pulmonary atresia with intact ventricular septum; report of a case].

A 5-year-old boy was referred to our institute for cardiac evaluation having been previously seen at another center. He had been diagnosed a pulmonary atresia with intact ventricular septum just after birth, and undergone Blalock-Taussig shunts. Although his central pulmonary artery pressure was high (mean pressure 26 mmHg) after bilateral Blalock-Taussig shunts, multiple peripheral pulmonary artery stenosis protected his pulmonary vascular bed from pressure load. We released the multiple pulmonary artery stenosis partly by catheter intervention and partly by surgical operation, and staged Fontan operation was completed. The surgery in combination with catheter therapies would expand the indication of Fontan-type operation, and it would contribute to the patients' postoperative prognosis.
