What is cryoablation?
Cryoablation involves the use of extreme low temperatures to freeze and remove unwanted tissue and cells, often using cotton swab or spray device. Minimally invasive technique includes the use of liquid nitrogen or argon gas on cells and tissue located inside or outside the body. Usually cryoablation, also referred to as cryotherapy or cryosorurgia, is used for different conditions, including certain types of cancer and tumors, as well as moths and nodes. Cyrotherapy is often performed only using only local anesthesia and is usually performed on the basis of a facial base. While cryosurgia may have some benefits, its long -term efficiency is unknown.
During the procedure, the fluid is frozen outside the cells, causing cell dehydrate. Once the cells reach a temperature of -40 degrees Fahrenheit (about - 40 Celsius), the cells die after clotting. It usually takes about 10 minutes for the cells to reach the killing temperature that is maintained for at least 10 minutes to ensure the death of undesirable cells or tissueE.
For removal of unwanted cells or tissue on the skin, liquid nitrogen is applied locally. Frozen tissue or cells dissolve and soon creates rattle. For cells or tissues that need to be removed internally, the procedure is more complicated. Internally freezing cells or tissues freezing can take up to three hours.
sedative drug is administered intravenously and in an area near unwanted internal cells or tissues is a small cut. Using ultrasound or MRI, the doctor will lead a hollow tool called Kryoprobe, which contains liquid nitrogen or argon gas into the skin. Around Kryoprobe there is a ball of ice to freeze the necessary cells and tissues. Frozen cells and tissues are then sucked in the body.
Cryoablation is often used to treat many cancers, including retinoblastoma, cancer that affects the retina during childhood. The procedure is also used for men who have prostate cancer that is limitedAnd the prostate. Cryoabization can be used to treat liver cancer that has not reached other parts of the body.
The process of freezing undesirable cells or tissue minimizes the complications of surgery such as pain and bleeding. When used to treat kidney and liver tumors, recovery time is much less than removal of tumors by other surgery. Kryoabization can also be used as a method of treatment for people who may not be ideal candidates for conventional surgery due to age or health restrictions.
The procedure is associated with a handful of risks and disadvantages. Since the procedure can only be performed in a localized area, it is possible for doctors to lack microscopic pieces of cancer. There is a risk that sexual impotence may occur in the fight against prostate cancer because the nerves involved in sexual reproduction are frozen. If treatment is used to treat skin conditions, scarring, swelling and pigmentation loss may develop.
