Organ donation is the process when a person allows an organ of their own to be removed and transplanted to another person, legally, either by consent while the donor is alive or dead with the assent of the next of kin.
Organ transplantation is a medical procedure in which an organ is removed from one body and placed in the body of a recipient, to replace a damaged or missing organ. The donor and recipient may be at the same location, or organs may be transported from a donor site to another location. Organs and/or tissues that are transplanted within the same person's body are called autografts. Transplants that are recently performed between two subjects of the same species are called allografts. Allografts can either be from a living or cadaveric source.
Jesica Santillan was a Mexican national who died after an organ transplant operation in which she received the heart and lungs of a patient whose blood type did not match hers. Doctors at the Duke University Medical Center failed to check the compatibility before surgery began.
A pancreas transplant is an organ transplant that involves implanting a healthy pancreas into a person who usually has diabetes.
Liver transplantation or hepatic transplantation is the replacement of a diseased liver with the healthy liver from another person (allograft). Liver transplantation is a treatment option for end-stage liver disease and acute liver failure, although availability of donor organs is a major limitation. The most common technique is orthotopic transplantation, in which the native liver is removed and replaced by the donor organ in the same anatomic position as the original liver. The surgical procedure is complex, requiring careful harvest of the donor organ and meticulous implantation into the recipient. Liver transplantation is highly regulated, and only performed at designated transplant medical centers by highly trained transplant physicians and supporting medical team. The duration of the surgery ranges from 4 to 18 hours depending on outcome. Favorable outcomes require careful screening for eligible recipient, as well as a well-calibrated live or cadaveric donor match.
A heart–lung transplant is a procedure carried out to replace both heart and lungs in a single operation. Due to a shortage of suitable donors and due to the fact that both heart and lung have to be transplanted together, it is a rare procedure; only about a hundred such transplants are performed each year in the United States.
Eisenmenger syndrome or Eisenmenger's syndrome is defined as the process in which a long-standing left-to-right cardiac shunt caused by a congenital heart defect causes pulmonary hypertension and eventual reversal of the shunt into a cyanotic right-to-left shunt. Because of the advent of fetal screening with echocardiography early in life, the incidence of heart defects progressing to Eisenmenger syndrome has decreased.
Kidney transplant or renal transplant is the organ transplant of a kidney into a patient with end-stage kidney disease (ESRD). Kidney transplant is typically classified as deceased-donor or living-donor transplantation depending on the source of the donor organ. Living-donor kidney transplants are further characterized as genetically related (living-related) or non-related (living-unrelated) transplants, depending on whether a biological relationship exists between the donor and recipient.
Lung transplantation, or pulmonary transplantation, is a surgical procedure in which one or both lungs are replaced by lungs from a donor. Donor lungs can be retrieved from a living or deceased donor. A living donor can only donate one lung lobe. With some lung diseases, a recipient may only need to receive a single lung. With other lung diseases such as cystic fibrosis, it is imperative that a recipient receive two lungs. While lung transplants carry certain associated risks, they can also extend life expectancy and enhance the quality of life for those with end stage pulmonary disease.
Transfusion-related acute lung injury (TRALI) is the serious complication of transfusion of blood products that is characterized by the rapid onset of excess fluid in the lungs. It can cause dangerous drops in the supply of oxygen to body tissues. Although changes in transfusion practices have reduced the incidence of TRALI, it was the leading cause of transfusion-related deaths in the United States from fiscal year 2008 through fiscal year 2012.
The United Network for Organ Sharing (UNOS) is a non-profit, scientific and educational organization that administers the only Organ Procurement and Transplantation Network (OPTN) in the United States, established by the U.S. Congress in 1984 by Gene A. Pierce, founder of United Network for Organ Sharing. Located in Richmond, Virginia, the organization's headquarters are situated near the intersection of Interstate 95 and Interstate 64 in the Virginia BioTechnology Research Park.
Organ procurement is a surgical procedure that removes organs or tissues for reuse, typically for organ transplantation.
Idiopathic pulmonary fibrosis (IPF), or (formerly) fibrosing alveolitis, is a rare, progressive illness of the respiratory system, characterized by the thickening and stiffening of lung tissue, associated with the formation of scar tissue. It is a type of chronic scarring lung disease characterized by a progressive and irreversible decline in lung function. The tissue in the lungs becomes thick and stiff, which affects the tissue that surrounds the air sacs in the lungs. Symptoms typically include gradual onset of shortness of breath and a dry cough. Other changes may include feeling tired, and abnormally large and dome shaped finger and toenails. Complications may include pulmonary hypertension, heart failure, pneumonia or pulmonary embolism.
The National Organ Transplant Act (NOTA) of 1984 is an Act of the United States Congress which established the framework for the U.S. organ transplant system. The act clarified the property rights of human organs from deceased individuals and created a public-private partnership known as the Organ Procurement and Transplantation Network (OPTN), which was empowered to manage organ allocation on a national basis.
Transplantable organs and tissues may refer to both organs and tissues that are relatively often transplanted, as well as organs and tissues which are relatively seldom transplanted. In addition to this it may also refer to possible-transplants which are still in the experimental stage.
ABO-incompatible (ABOi) transplantation is a method of allocation in organ transplantation that permits more efficient use of available organs regardless of ABO blood type, which would otherwise be unavailable due to hyperacute rejection. Primarily in use in infants and young toddlers, research is ongoing to allow for increased use of this capability in adult transplants. Normal ABO-compatibility rules may be observed for all recipients. This means that anyone may receive a transplant of a type-O organ, and consequently, type-O recipients are one of the biggest beneficiaries of ABO-incompatible transplants. While focus has been on infant heart transplants, the principles generally apply to other forms of solid organ transplantation.
The Sarah Murnaghan lung transplant controversy began in late May 2013, when the parents of a ten-year-old Philadelphia area girl with cystic fibrosis, Sarah Murnaghan, launched a campaign to change the under-12 policy of the United Network for Organ Sharing (UNOS), which they asserted was age discrimination. Her plight received considerable media attention, particularly because Kathleen Sebelius, Secretary of Health and Human Services, refused to intervene to grant an exception to the rule.
Intestine transplantation is the surgical replacement of the small intestine for chronic and acute cases of intestinal failure. While intestinal failure can oftentimes be treated with alternative therapies such as parenteral nutrition (PN), complications such as PN-associated liver disease and short bowel syndrome may make transplantation the only viable option. One of the rarest type of organ transplantation performed, intestine transplantation is becoming increasingly prevalent as a therapeutic option due to improvements in immunosuppressive regimens, surgical technique, PN, and the clinical management of pre and post-transplant patients.
Organ donation is when a person gives their organs after they die to someone in need of new organs. Transplantation is the process of transplanting the organs donated into another person. This process extends the life expectancy of a person suffering from organ failure. The number of patients requiring organ transplants outweighs the number of donor organs available.
Kidney paired donation (KPD), or paired exchange, is an approach to living donor kidney transplantation where patients with incompatible donors swap kidneys to receive a compatible kidney. KPD is used in situations where a potential donor is incompatible. Because better donor HLA and age matching are correlated with lower lifetime mortality and longer lasting kidney transplants, many compatible pairs are also participating in swaps to find better matched kidneys. In the United States, the National Kidney Registry organizes the majority of U.S. KPD transplants, including the largest swaps. The first large swap was a 60 participant chain in 2012 that appeared on the front page of the New York Times and the second, even larger swap, included 70 participants and was completed in 2014. Other KPD programs in the U.S. include the UNOS program, which was launched in 2010 and completed its 100th KPD transplant in 2014, and the Alliance for Paired Donation.
