Fontan operation, new results and modifications

Back ground: Since the first Fontan operation, various techniques have been described. These methods have been changed during the time. Now new drugs are also being used beside surgery. Case reports: Fifteen patients with mean age of 8 years and diagnosis of tricuspid atresia or D TGA and single ventricle were operated in our hospital .All of them ,except one were operated with extra cardiac technique and fenestration was created in half due to CVP ( In seven cases ). We had one mortality and three case of postoperative morbidities .The major complications were pleural and pericardial effusion and chylothorax . We treated two patients inflicted with effusion with oral Sildenafil sulfate(Viagra) therapy. Conclusion: The mortality in our study was comparable to other studies .We prefer to have a fenestration between conduit and RA even with low CVP . Oral Sildenafil therapy would reduce pulmonary artery pressure in complicated patients.
