Hi, my situation was different. I actually developed pleural effusion about 6 weeks post liver transplant. I had to have fluid drained weekly for about 4 weeks. Then the decision was made to have a tube inserted in my chest to drain all the fluid. I had to go into the hospital for 3 days until the fluid was drained and they watched to be sure I did not get any infections. Once the fluid was drained they insert medicine into me to patch up the space where the fluid was coming from.
Just thought I would share my experience.
Good luck!
