Organ Transplant

Organ transplant is the surgical replacement of an organ that is damaged to the point where it can no longer function with a healthy organ from a living or deceased donor.

Organ transplant is the process of replacing a dysfunctional organ with a healthy organ from a living or deceased donor. One of the most effective treatment methods for patients with advanced organ failure, this procedure includes the selection of a suitable donor, surgical operation, and regular follow-up after transplantation.

What is Organ Transplant?

Organ transplant is the process of replacing an organ that is damaged to the point where it can no longer function with a healthy organ from a living donor or a brain-dead deceased donor. The aim is to eliminate the life-threatening condition caused by organ failure and to extend the patient's lifespan.

Organ transplantation usually comes into play in cases of end-stage organ failure, where the organ can no longer function adequately and medication/other treatments are insufficient. At this point, organ transplantation can be the most effective and permanent treatment option for many patients.

What are the Types of Organ Transplantation?

Organ transplantation types are classified according to who the transplanted organ is taken from and the compatibility between the donor and the recipient. Not all transplants are performed in the same way; some are done with the person's own tissue, some with another person, and some with special methods. The types of organ transplantation are:

Autograft

An autograft is the transplantation of a person's own tissue back to themselves. Since the donor and recipient are the same person, the risk of the immune system rejecting the organ is quite low. It is more commonly seen in tissue transplants.

Allograft

An allograft is a transplant performed between individuals of the same species, i.e., from person to person, but between genetically different individuals. It is the most frequently performed type of organ transplant today. Immune compatibility is of great importance in this type.

Isograft

An isograft is a transplant performed between genetically identical individuals. The best-known example is transplants between identical twins. Due to genetic similarity, the risk of rejection is low.

Cenograft

A cenograft is a transplant performed between different species. For example, tissue or organ transplants from animals to humans fall into this category. Due to the difference in species, special assessments regarding the immune system are required.

Split Transplants

In this method, an organ taken from a donor is divided so that it can be transplanted to two different people. It can be applied especially in liver transplants. It is an important option in cases where there are many patients waiting for organs.

Domino Transplants

In a domino transplant, while a new organ is transplanted to one patient, the organ removed from the patient can be transplanted to another patient under suitable conditions. This method creates a chain transplant process.

ABO Incompatible Transplants

ABO incompatible transplants are transplants performed with certain medical preparations despite the lack of blood group compatibility. These types of transplants require more careful planning and follow-up.

From Whom Are Organ Transplants Performed?

Organ transplants are performed from living donors who meet the appropriate health criteria or from cadaver donors who have suffered brain death. Organ transplants cannot be performed from just anyone who wants one. The donor's general health status, whether they carry infectious diseases, organ functions, and tissue compatibility are examined with detailed tests.

Living Donor

A living donor is a person who donates an organ of their own free will and if found medically suitable. In live organ transplantation, relatives up to the 4th degree can be used as donors:

1st degree relatives: mother, father, child
2nd degree relatives: sibling, grandfather, grandmother, grandchild
3rd degree relatives: uncle, aunt, nephew/niece
4th degree relatives: children of 3rd degree relatives

In non-related organ transplants, recipients and donors are evaluated by ethics committees established within the Provincial Health Directorate. If the ethics committee confirms that there are no medical, ethical, or legal problems between the individuals, they are accepted for transplantation.

Cadaver Donor

A cadaver donor is a person whose brain death has been medically confirmed and who has irreversibly lost their life. The organs of individuals who have suffered brain death can be used for transplantation after family consent and completion of legal procedures. Cadaver donation is one of the most important sources for patients waiting for organs.

Which Organs and Tissues Are Transplanted?

The organs and tissues that can be transplanted are determined within the framework of medical suitability and legal regulations. The most frequently transplanted organs today are:

Kidney
Liver
Heart
Lung
Pancreas
Small Intestine

These organs are generally vital for patients who develop end-stage organ failure. Kidney and liver transplants, in particular, are among the most common organ transplants that can be performed from living donors.

In addition to organ transplantation, various tissues can also be transplanted. The most frequently transplanted tissues are:

Cornea (the transparent layer of the eye)
Bone marrow (stem cell transplant)
Heart valves
Vascular grafts
Bone and cartilage tissue
Others

Tissue transplants are generally life-saving and restore organ function. For example, corneal transplantation can restore vision in patients experiencing vision loss. Who Can Be an Organ and Tissue Donor?

Who Can Be an Organ and Tissue Donor?

There are some basic requirements for being a living organ donor:

Being 18 years of age or older
Having sound mental health
Making a voluntary and uncoerced decision
Not having a serious chronic illness
Having healthy organ function

Living donors can generally donate organs such as kidneys and a portion of the liver. Donor candidates undergo detailed medical examinations, and the safety of the donation for both the donor and the recipient is assessed.

Anyone can declare their desire to donate organs while they are alive. Individuals who have suffered brain death can become organ and tissue donors after family consent and completion of legal procedures.

Similarly, general health status is assessed for tissue donation. Some tissues, such as the cornea, can be donated within certain age limits and provided there are no infectious diseases. Age limits for tissue donation may vary depending on the type of tissue to be donated.

Who Can Receive Organ Transplantation?

Organ transplantation can be applied to patients who have developed end-stage organ failure and do not benefit sufficiently from existing treatment methods. Organ transplantation is generally considered in the following cases:

End-stage renal failure
Advanced liver failure
Heart failure
Lung failure
Pancreatic failure
Intestinal failure

When drug treatment, dialysis, or other supportive methods are insufficient for these patients, organ transplantation may be the most effective treatment option.

There is no strict upper age limit for organ transplantation. What is important is the patient's biological age, general health status, and tolerance to surgery. Suitable patients can be transplant candidates even at an advanced age.

Where and How to Donate Organs?

Organ donation can be done at the following institutions and organizations:

Hospitals
Provincial Health Directorates
Police Directorates (during driver's license application or renewal)
Organ transplant centers
Foundations and associations operating in the field of organ transplantation
Health centers that accept organ donations

Today, organ donation declarations can also be made via e-Government. Even if a donor card has been obtained, family consent is an important part of the process when brain death occurs. Therefore, it is recommended that individuals who wish to donate organs share their decision with their family members.

What is the Recovery Process Like After Organ Transplantation?

The recovery process after organ transplantation varies depending on the patient's general health and the type of transplanted organ. After the surgery, the patient is monitored in the hospital for a while, usually in intensive care, and the health and functioning of the organ are checked. After discharge, regular doctor check-ups and blood tests are performed.

Immunosuppressant drugs must be used daily and regularly to prevent the body from rejecting the organ. During this process, protecting against infections, maintaining a balanced diet, and following doctor's recommendations are of great importance. With regular follow-up and adherence to treatment, many patients can safely return to their daily lives over time.

What to Consider When Choosing an Organ Transplant Center?

When choosing an organ transplant center, experience, expert staff, and technical infrastructure are among the most important criteria. It is crucial that the center has a multidisciplinary team, offers advanced intensive care facilities, and implements a regular follow-up program. Furthermore, the number of transplants performed and the success rates of the center should also be considered in terms of reliability.

Medipol Health Care manages the organ transplant process with a holistic approach thanks to its experienced academic staff, advanced technological infrastructure, and patient-centered approach. Pre-operative preparation, surgery, and long-term post-transplant follow-up processes are carried out in a coordinated manner, offering patients a safe and comprehensive treatment option.
