Surgical treatment of partial anomalous pulmonary venous connection to the superior vena cava.

OBJECTIVE Surgical treatment of anomalous pulmonary venous connection to the superior vena cava, associated with sinus venous atrial septal defect, is well established and correlates with low mortality and morbidity. In order to reduce the incidence of stenosis or occlusion of the right superior vena cava, especially when associated with the presence of left superior vena cava, the right atrial appendage was used to enlarge the right superior vena cava, after the diversion of the anomalous pulmonary veins for the left atrium. METHODS Between June 1986 and September 2008, 95 consecutive patients were operated with anomalous drainage in the superior right vena cava and high right atrium. Ages ranged from 6 months to 68 years and females predominated with 50 cases. RESULTS There was no death in the immediate or late post operative care. The sinus cardiac rhythm was preserved in all cases and there was no complications in the late follow up. CONCLUSION This paper demonstrates the applicability of the technique described, with favorable results on mortality, rhythm disturbances and complications in the right superior vena cava.
