Superior vena cava reconstruction with homograft conduit under circulatory arrest.

Superior vena cava obstruction may be due to benign or malignant causes. This may be treated surgically by using autologous saphenous vein grafts, autologous pericardial patches cut and reconstituted as tubes, expanded polytetrafluoroethylene grafts, or percutaneously by balloon dilatation and stenting procedures. We report a case of superior vena cava obstruction in which the obstructed segment was bypassed using a tube constructed from aortic and pulmonary homograft conduits, under hypothermic circulatory arrest without using jugulo-atrial shunts, leaving the obstructed segment in situ.
