Plasmapheresis before thymectomy in myasthenia gravis: routine versus selective protocols.

Objective: The value of thymectomy in management of myasthenia gravis (MG) is well recognized. Plasmapheresis (PMP) before thymectomy appears to improve the postoperative outcome. As PMP has its own complications, selective use of PMP preoperatively for patients at risk of post-thymectomy complications would improve the postoperative outcome, and decreases the PMP-related complications.
