Case Series: Clinical Impact of Plasmapheresis and Thymectomy on Early-Onset Myasthenia Gravis.

Thymectomy is a common procedure performed in cases of myasthenia gravis (MG) with a thymoma or general MG that does not improve with medical therapy. This procedure is usually preceded by plasmapheresis to prevent the occurrence of myasthenic crisis and improve clinical outcome after thymectomy. Early-onset MG has a different phenotype than late-onset MG.
