[Pulmonary thromboembolism after lung resection in patients with schizophrenia; report of 2 cases].

We report 2 cases of pulmonary thromboembolism after lung resection in patients with schizophrenia. The first case is a 67-year-old woman. She underwent right lower lobectomy for primary lung cancer and suddenly felt dyspnea 2 days after the operation. She was diagnosed pulmonary thromboembolism by computed tomography (CT) and lung perfusion scintigram, and recoverd soon. The second case is a 42-year-old man. He underwent partial resection of the right lung for metastatic germ cell tumor. Six days after the operation, he fell into acute respiratory failure and died in spite of resuscitation. The autopsy showed that the cause of death was pulmonary thromboembolism. Because patients with schizophrenia have high-risk of pulmonary thromboembolism, extreme care must be exercised to avoid it.
