My 18 year old daughter was almost totally resistant to the repeated rounds of SoluMedrol (5 days each time), so in the last two months, she has been hospitalized twice for PLEX (also called TPE, or
Therapeutic Plasma Exchange). Each time, a Shiley catheter was implanted in her right internal jugular vein (neck), and she received 7 every other day Plasma Exchange.
The first round in October, she had spectacular recovery, but that only lasted for 2.5 weeks.
