Case Reports[Clipping of the thoracic duct with video-assisted thoracic surgery in the treatment of chylothorax after pulmonary resection].
We describe a procedure for video-assisted thoracoscopic clipping of the thoracic duct to treat postoperative chylothorax. This technique was successfully performed on a 62-year-old man who developed chylothorax following right lower lobectomy and partial resection of the 11th and 12th vertebral bodies for squamous cell lung cancer. Because conservative therapy for 7 days failed to reduce the amount of pleural effusion, we performed thoracoscopic examination of the thoracic duct and found a site leaking chylous fluid. ⋯ Generally, chylothorax complicating pulmonary resection has been managed by medical treatment first, followed by surgical intervention in case that fail to respond to initial therapy. The newly designed video-assisted thoracic surgery procedure reduces the trauma, shortens the drainage period and hospital stay, and provides better exposure of the thoracic duct. We believe that this procedure can be carried out shortly after the occurrence of chylothorax.

[Three-dimensional transesophageal echocardiographic assessment for prosthetic valves].
We evaluated three-dimensional transesophageal echocardiographic assessment of the implanted mechanical valves by rotational scanning method. Patients were 7 mitral valve replacement and one aortic valve replacement, 2 mitral and aortic valve replacement. In 2 cases of 7 mitral valve replacement, the prosthetic valve regurgitation was evaluated using by color Doppler echocardiography. ⋯ In this study, this system has some problems, for example real-time evaluation is impossible, aortic valve and ball valve cases cannot be reconstructed. However, we think that this new technology is suitable for evaluating valve thrombus, valve dysfunction and paravalvular leakage. In conclusion, the three-dimensional echo-cardiography demonstrated, reliable and accurate examination, and it can evaluate various complications of prosthetic valve.
