Please tell me about pneumothrax, pleurodesis?

Diagnosis / treatmen: Pneumothorax is a diagnosis of air in the pleural space in which the lung resides. It is somethimes treated or prevented from re occuring by the procedure called pleurodesis. The pluerodesis procedure creates adhesion of the plureal surfaces of the lung with the pleural surface of the outer lung cavity so that air is not allowed to expand into this space.

Depends cause: Depending cause of pneumothorax.... Spontaneous pneumothorax first recurrence rates depending on type ranges 20-40+%. These details as well as lifestyle, may encourage recommend investigation and possibly vats pleurodesis to prevent/decrease risk of further recurrence.
