Organ & Tissue Transplantation: Indications, Types, Risks & Decision-Making

Transplantation replaces a failing organ, tissue, or cell with a healthy one from a donor (deceased or living). It is a life-saving but complex intervention requiring lifelong management.

Commonly Transplanted Organs & Tissues

  • Organs: Kidney, liver, heart, lung, pancreas, intestine (single or combined)
  • Tissues: Cornea, skin, bone, tendons, heart valves, veins
  • Cells: Hematopoietic stem cells (bone marrow, peripheral blood, cord blood), pancreatic islets

Primary Indications

  • End-Stage Organ Failure: ESRD (kidney), cirrhosis (liver), cardiomyopathy (heart), COPD/IPF (lung), T1DM with complications (pancreas/islets).
  • Severe Tissue Destruction: Major burns (skin), traumatic bone loss, valvular destruction.
  • Genetic/Metabolic Disorders: Cystic fibrosis (lung), metabolic liver diseases, immunodeficiencies (stem cell).
  • Malignancy: Leukemia/lymphoma (allogeneic stem cell); select solid tumors (liver transplant for HCC within criteria).

Key Risks

  • Rejection: Acute (days–months) or chronic (years); requires lifelong immunosuppression.
  • Infection: Opportunistic (CMV, BK virus, fungi, TB) due to immunosuppression.
  • Surgical Complications: Bleeding, thrombosis, anastomotic leak, biliary/ureteral strictures.
  • Immunosuppression Toxicity: Nephrotoxicity (CNI), diabetes, hypertension, dyslipidemia, malignancy (skin, PTLD), bone loss.
  • Donor-Derived Risks: Infection, malignancy, HLA mismatch.

The Decision Process

  1. Referral & comprehensive evaluation (medical, psychosocial, financial, support system).
  2. Listing on national waitlist (UNOS/OPTN in US) — priority by MELD, LAS, heart status, etc.
  3. Living donor workup (if applicable) — often faster, better outcomes for kidney/liver.
  4. Informed consent: detailed discussion of risks, benefits, alternatives, and lifelong commitments.

Transplantation is a partnership between patient, caregivers, and a multidisciplinary team. Success depends on adherence, surveillance, and shared decision-making.
