[Malignant mediastinal lesions with invasion to the superior vena cava].
Four patients underwent resection of mediastinal malignant tumors with invasion to the superior vena cava. Two patients had invasive thymoma, one seminoma, and one metastatic mediastinal lymph nodes of unknown origin. Prior to resection of the tumor, an ePTFE graft was anastomosed between the innominate vein and the right atrium to maintain the venous drainage from the brain and the upper extremities. In two patients, the superior vena cava was reconstructed by patch angioplasty after the tumor with a part of the vena cava was safely resected. One patient died of acute respiratory failure, but the other three are alive and well without any evidence of graft obstruction. This safe and useful method in order to prevent cerebral congestion during and after resection of the tumor.
