Warden Technique: Anomalous Pulmonary Venous Drainage
Partial anomalous pulmonary venous connections (PAPVC) are a very heterogeneous group of lesions, in which at least one pulmonary vein is draining into the systemic venous system. These congenital lesions are frequently associated with atrial septal defects (ASD), typically the sinus venous type of defect.The type of correction must be determined based on the site of drainage of these anomalous veins.
The authors present a case of 6-year-old child with an anomalous venous drainage from the superior and medial lung lobes to the superior vena cava, associated with a large ASD. This video demonstrates the authors’ preferred technique for repairing these congenital defects, using the warden technique. The authors believe that the warden technique is a safe and reproducible way to correct almost every case of anomalous drainage. In the long term, this type of repair may protect from rhythm disturbances and from venous pathway obstruction.
