Isolated organ perfusion technique
Isolated organ perfusion is a medical technique used in the treatment of cancer and other diseases. It involves the isolation of an organ from the body's general circulation and the subsequent perfusion of the organ with a solution containing therapeutic agents. This technique allows for the delivery of high concentrations of drugs to the organ without systemic toxicity.
History[edit | edit source]
The concept of isolated organ perfusion was first introduced in the 1950s by the Swedish surgeon Hans Krebs. He used the technique to study the metabolism of isolated organs. In the 1960s, the technique was adapted for the treatment of cancer by James Ewing, an American oncologist.
Technique[edit | edit source]
Isolated organ perfusion is performed under general anesthesia. The organ to be treated is isolated from the body's general circulation by clamping the blood vessels that supply it. A catheter is then inserted into the organ's main artery, and a solution containing the therapeutic agents is perfused through the organ. The solution is then drained from the organ and discarded.
The technique allows for the delivery of high concentrations of drugs to the organ without systemic toxicity. This is because the drugs are confined to the organ and do not enter the body's general circulation.
Applications[edit | edit source]
Isolated organ perfusion is used in the treatment of various types of cancer, including melanoma, sarcoma, and liver cancer. It is also used in the treatment of certain non-cancerous conditions, such as hyperhidrosis and Raynaud's disease.
Advantages and Disadvantages[edit | edit source]
The main advantage of isolated organ perfusion is that it allows for the delivery of high concentrations of drugs to the organ without systemic toxicity. This can result in improved treatment outcomes and fewer side effects.
However, the technique also has some disadvantages. It is a complex procedure that requires specialized equipment and trained personnel. It also carries the risk of complications, such as infection and bleeding.
