Abstract:
A lateral extrapleural approach via video-assisted thoracic surgery (VATS) was used in a patient suspected of having a benign tumor of right lobe of the thymus. The patient previously had undergone lung resection for pulmonary tuberculosis, and the ipsilateral thorax had contracted and dense pleural adhesions were likely to exist. Lateral extrapleural approach by VATS was performed successfully and is an alternative to open surgery in highly selected patients with anterior mediastinal lesions.
