Abstract
A 65-year-old male underwent a right pneumonectomy for lung cancer. On the first operative day, cyanosis was appeared on the upper left half of the body. He felt dyspnea and became shock. Superior vena cava (SVC) syndrome was diagnosed by enhanced CT scans of the chest. There were extensive thrombi from the SVC to the left brachiocephalic vein. Emergency thrombectomy was performed, resulting in improvement of the patient's condition. However, the patient soon developed cyanosis again. We began the thrombolytic therapy, because relapsing thrombosis was strongly suspected. In response to this therapy, his symptom became better, and thrombi disappeared on the diagnostic images. The case was very rare, because the patient had no typical risk factor.
