Fluorescein-enhanced Autofluorescence Thoracoscopy in Patients with Primary Spontaneous Pneumothorax and Normal Subjects

Abstract

Lungs in patients with PSP show significantly more abnormalities at WLT when compared with normal subjects. High-grade FEAT lesions were exclusively present in PSP, and predominantly at lung zones that appeared normal at white light inspection. These findings suggest that significant parenchymal abnormalities are not limited to lesions visible during WLT, such as blebs and bullae.
