ABSTRACT

Objective To investigate clinical effects of video assisted thoracoscopic lung volume reduction surgery(LVRS) for severe emphysema. Methods Six patients with severe emphysema underwent lung volume reduction surgery by video assisted thoracoscopy.The LVRS was performed unilateraly in 4 and bilateraly in 2 through median stemination.20%～30% of total volume of lung was resected. Results There was no operative death.All patients were followed up for 3 to 17 months.After LVRS,the mean forced expiratory volume in 1 second(FEV 1) and PaO 2 increased by 24 6% and 8 3%,respectively,Total lung capacity(TLC),residual volume(RV) and ventilatory assistance decreased by 24 6%,20 3% and 47 1% respectively Conclusions LVRS by video-assited thoracoscopy is an effective and safe technique for patients with severe emphysema.It can relieve dyspnea and improve excise tolerance and the quality of life.
