Hi,
I had 3 rounds of plasmpheresis during the week prior to the thymectomy, but I didn't have a catheter put in. They just used the viens in my arms & wrists and said they would put a port in if they didn't hold up...I would not have made it through a fourth. In less you have a lot of incredible viens, I would recommend a catheter or port. I had a full sternum thymectomy in Nov. 02 and did not see the full benefits for 4 years. Any specific questions you have, I would be more than happy to answer. I wish you all the best and will keep you in my thoughts & prayers. Take care.
Hugs,
Pat
