The investigators intend to compare the group using triple-cuffed endobronchial tube (VentiBroncTM Anchor) with the group using the conventional double-lumen endotracheal tube (Shiley®) in patients at high risk of malposition of the double-lumen endotracheal tube. The aim of this study is to determine if the use of VentiBroncTM Anchor increases the success rate of optimal double-lumen intubation to left main bronchus.
