Can acute disseminated encephalomyelitis progress in a deferred way?
We postulate that the recurrent symptoms in our patient could be explained as a multiphasic disseminated encephalomyelitis (MDEM). Favourable outcome after simultaneous treatment with methylprednisolone and intravenous immunoglobulin is emphasized in this report.
Damage to the valves caused by decellularization technique is much less than the damage caused by the recipient's immune response. In vitro removal of viable cells in (cryopreserved) homografts may decrease graft failure. Seeding with autologous or major histocompatibility complex-matched donor endothelial cells will be necessary to diminish damage induced by an absent blood-tissue barrier.
