Partial or complete occlusion of the superior vena cava (SVC) by malignant tumor is frequently considered by many clinicians to be an indisputable sign of unresectability. Neoadjuvant therapy for locally advanced nonsmall cell lung carcinoma and malignant mediastinal tumors has enhanced the ability of the thoracic surgeon to accomplish a complete resection, including a portion or all of the SVC. If collateral circulation has not developed in the face of obstruction of the SVC, prolonged cross-clamping of the venous drainage to the upper third of the patients body can result in acute cerebral edema. Dartevelle and associates [1, 2] have described a technique for cross-clamping and replacement of the SVC with minimal complications. However, we have been reluctant to resect the SVC with this technique, preferring instead to fashion a shunt maintaining upper venous drainage and avoiding this possibly fatal neurologic complication.
The technique described in our original article [3] uses an intraluminal shunt to permit continuous venous flow into the right atrium during resection and reconstruction of the superior vena cava under very controlled conditions. Rather than performing an en-bloc resection of the lung, nodes, and SVC as advocated by others [4], we chose to complete the pulmonary resection first, optimizing the exposure for the SVC resection and reconstruction. In most cases, the defect can be closed with either a patch or direct suture repair. If complete resection and tube graft replacement of the vena cava is required, the shunt can be repositioned through the graft during a very short period of cross-clamping.
Our updated experience with this technique is presented in Table 1. Follow-up of our initial 6 patients is provided, together with our experience with an additional 5 patients. We continue to favor the use of pericardium as our material of choice to patch the SVC defect, although others have successfully used a thin polytetrafluoroethylene cardiovascular patch. In 2 patients, the entire circumference of the SVC was resected, necessitating an interposition graft of externally supported 13-mm polytetrafluoroethylene as described by others [57].

years after a resection. This experience, and the absence of any neurologic problems in shunted patients, have encouraged us to shunt rather than cross-clamp the SVC. The long-term patency of the SVC and the absence of thrombus or pulmonary emboli even without anticoagulation have been gratifying. The 5-year survival in 4 of 11 patients indicates that an aggressive approach to these locally advanced malignancies is justified.
