Why Organ transplant ??!!
6
organ transplant (an operation moving an organ
from one organism (the donor) to another (the
recipient)) "he had a kidney transplant" "the
long-term results of cardiac transplantation are
now excellent" "a child had a multiple organ
transplant two months ago"
7
Types of transplants
  • Autograft
  • Allograft
  • Isograft
  • Xenograft and Xenotransplantion
  • Split transplants
  • Domino transplants

8
Autograft
  • A transplant of tissue from one to oneself.
    Sometimes this is done with surplus tissue, or
    tissue that can regenerate, or tissues more
    desperately needed elsewhere (examples include
    skin grafts, for CABG, etc.) Sometimes this is
    done to remove the tissue and then treat it or
    the person, before returning it (examples include
    stem-cell autograft and storing blood in advance
    of surgery).

9
Allograft
  • An allograft is a transplanted organ or tissue
    from a genetically non-identical member of the
    same species. Most human tissue and organ
    transplants are allografts.

11
Isograft
  • A subset of allografts in which organs or tissues
    are transplanted from a donor to a genetically
    identical recipient (such as an identical twin).
    Isografts are differentiated from other types of
    transplants because while they are anatomically
    identical to allografts, they are closer to
    autografts in terms of the recipient's immune
    response.

12
Xenograft and Xenotransplantion
  • A transplant of organs or tissue from one species
    to another. Xenotransplantion is often an
    extremely dangerous type of transplant. Examples
    include porcine heart valves, which are quite
    common and successful, a baboon-to-human heart
    (failed), and piscine-primate (fish to non-human
    primate) islet (i.e. pancreatic or insular
    tissue), the latter's research study directed for
    potential human use if successful. See
    xenotransplantation.

14
Split transplants
  • Sometimes, a deceased-donor organ (specifically
    the liver) may be divided between two recipients,
    especially an adult and a child.

15
Domino transplants
  • This operation is usually performed for cystic
    fibrosis as both lungs need to be replaced and it
    is a technically easier operation to replace the
    heart and lungs en bloc. As the recipient's
    native heart is usually healthy, this can then
    itself be transplanted into someone needing a
    heart transplant. That term is also used for a
    special form of liver transplant, in which the
    recipient suffers from familial amyloidotic
    polyneuropathy in which the liver (slowly)
    produces a protein that damages other organs
    their liver can be transplanted into an older
    patient who is likely to die from other causes
    before a problem arises.

16
Major organs and tissues transplanted
  • Thoracic organs
  • Heart (Deceased-donor only)
  • Lung(Deceased-donor and Living-Donor)
  • En bloc Heart/Lung (Deceased-donor and Domino
    transplant)
  • Other organs
  • Kidney (Deceased-donor and Living-Donor)
  • Liver (Deceased-donor and Living-Donor)
  • Pancreas (Deceased-donor only)
  • (Deceased-donor only)
  • Tissues, cells, fluids
  • Hand (Deceased-donor only
  • Cornea (Deceased-donor onlySkin graft including
    Face transplant (almost always autograft)
  • Penis (Deceased-donor only)
  • Islets of Langerhans (Pancreas Islet Cells)
    (Deceased-donor and Living-Donor)
  • Bone marrow/Adult stem cell (Living-Donor and
    Autograft)
  • Blood transfusion/Blood Parts Transfusion
    (Living-Donor and Autograft)
  • Blood vessels (Autograft and Deceased-Donor)
  • Heart valve (Deceased-Donor, Living-Donor and
    XenograftPorcine/bovine)
  • Bone (Deceased-Donor, Living-Donor, and
    Autograft)

History of Organ transplant
19
The Chinese physician Pien Chi'ao reportedly
exchanged hearts between a man of strong spirit
but weak will with one of a man of weak spirit
but strong will in an attempt to achieve balance
in each man.

  • Roman Catholic accounts report the third-century
    saints Damian and Cosmas as replacing the
    gangrenous leg of the Roman deacon Justinian with
    the leg of a recently deceased Ethiopian.

21
  • The first reasonable account is of the Indian
    surgeon Sushruta in the second century BC, who
    used autografted skin transplantation in nose
    reconstruction rhinoplasty.

22
  • Centuries later, the Italian surgeon performed
    successful skin autografts he also failed
    consistently with allografts

23
  • the first successful human corneal transplant, a
    keratoplastic operation, was performed by Eduard
    Zirm in Austria in 1905.

24
  • Their skillful anastomosisoperations, the new
    suturing techniques, laid the groundwork for
    later transplant surgery and won Carrel the 1912
    Nobel Prize for Medicine or Physiology

25
  • Archibald McIndoe

carried on the work into World War II as
reconstructive surgery
26
  • The first attempted human deceased-donor
    transplant was performed by the Ukrainian surgeon
    in the 1930s

27
  • the late 1940s Peter Medawar, working for the
    National Institute for Medica Research, improved
    the understanding of rejection. Identifying the
    immune reactions in 1951 Medawar suggested that
    immunosuppressive drugs

28
  • On March 9th 1981 t the first successful
    heart-lung transplant took place at Stanford
    University Hospital. The head surgeon, Bruce
    Reitz, credited the patient's recovery to
    cyclosporine-A.

Reasons for donation
31
Living related donors
32
Paired-exchange
33
Good Samaritan
34
Compensated donation
35
Forced donation
36
Ethical concerns
37
Who will buy ... my beautiful kidney?
38
Ethical concerns
  • The World Health Organization argues that
    transplantations promote health, but the notion
    of transplantation tourism has the potential to
    violate human rights or exploit the poor

There is also a powerful opposing view, that
trade in organs, if properly and effectively
regulated to ensure that the seller is fully
informed of all the consequences of donation, is
a mutually beneficial transaction between two
consenting adults, and that prohibiting it would
itself be a violation of Articles 3 and 29 of the
Universal Declaration of Human Rights.
