Abstract:
Direct hepatic veins-to-hemiazygos connection offers the balanced distribution of hepatic venous blood to both lungs, not requiring anticoagulation. We report a 13-year follow-up after this type of off-pump Fontan completion. Patient's hepatic veins-to-hemiazygos confluence increased with growth to allow for unobstructed flow. This unique technique can be recommended in heterotaxy patients, if atrial hepatic venous drainage and hemiazygos vein are in close proximity.
