My husband has a "trapped lung".  He also has CHF.  There is fluid
around that lung.   It is affecting his breathing.  The doctor
believes, and I agree, that in his weakened conditon surgery to fix
the lung would be too much of a strain.

The cardiologist said there was a way to drain the fluid and put
something there to prevent it from recurring.  I don't remember what
he said about how this is done.  I only remember he said that first
they would have to dehydrate my husband.

Is anyone familiar with this procedure?   Does it have a name?  He's
already had a thoracentsis done but the fluid returned in a couple of
days.
