Abstract background and objective: primary spontaneous pneumothorax (psp) is a common condition that typically affects young adults. With recent advances in techniques, vats is now a safe and accepted procedure for treating psp. Lung isolation techniques have been commonly used to facilitate surgical procedures in the past. The purpose of this study was to evaluate the feasibility of using a single-lumen endotracheal tu.
