Therapeutic Plasmapheresis

Removal of circulating antibodies through plasma exchange, particularly useful in antibody-mediated rejection episodes.

procedure

Enhanced Graft Surveillance

Intensified monitoring of graft function through frequent laboratory tests, imaging, and biopsy to assess treatment response.

monitoring

Anti-Thymocyte Globulin or Antigen-Specific Therapy

Biologic agents targeting T-cell mediated rejection when steroid therapy fails to achieve adequate response.
