I had VATS for thymic hyperplasia first, but later on i had second surgery for cardio mitral valve repair with medium sternotomy. Cardiothoracic surgeon had to clean up previous VATS surgery scars around thymus area. With VATS post OP, i suffered more pain with tube stucking out left rib cage. I had 3 plasmapheresis sessions before VATS Thymectomy. For heart surgery, i skipped the plasmapheresis just took shot of steroid. On the 2nd and 3rd day after heart surgery, Myasthenic Crisis hit me like a brick and almost got me for good. I cant remember how many plasmapheresis sessions got me out of the woods. There are many questions, reasons, why, what happened for further discussion. Most important thing i have learn is that Post OP team is very important.
Sorry if i over shared.

God Bless
