Spontaneous closure of arterio-venous pulmonary fistulas by redirection of hepatic venous blood 9 years after Glenn anastomosis in a 12-year-old girl.

We report on a 12-year-old girl with Ebstein's anomaly after a unidirectional Glenn procedure with surgical ligation of the proximal right pulmonary artery, who suffered from significant central cyanosis caused by multiple arterio-venous fistulas in the right lung. The continuity between the right pulmonary artery and the pulmonary trunk was restored with the use of radiofrequency perforation and consecutive covered stent implantation.
