Where would circulation of fluids go after pleurodesis surgery?

Normal: Pleurodesis surgery is a procedure to help fuse portions of the lung to the chest wall, and thus preventing abnormal fluid from forming around the lung. The abnormal fluid stops forming, depending on its cause, and your other normal body fluids continue to do the right thing.

Stay in circulation: Fluid in chest cavity in the form of effusion is abnormal. By eliminating the ability/ease of the fluid to abnormally accumulate in the thoracic space, pleuradesis keeps the fluid in normal circulation. In some situations, after pleuradesis of one side, the fluid will accumulate in the opposite side of the chest. This will necessitate pleuradesis on the otherside too.
