Cryoablation
Cryoablation, is a non-surgical procedure that uses cold to destroy tissue. During the procedure, a cryoprobe is inserted into the tissue and cooled with a liquid such as liquid nitrogen, liquid nitrous oxide, or compressed argon gas. The tissue is then frozen and thawed repeatedly, which destroys the diseased tissue while sparing healthy tissue.
Cryoablation is used to treat certain types of cancer and some conditions that may become cancer. It is used to treat tumors when surgical removal may be difficult or impossible, such as bone, kidney, lung, or liver tumors.
When is the procedure recommended?
- Cryoablation for cancer is typically used when surgery isn't an option.
- Cryoablation is sometimes used as a treatment for many types of cancer, including: kidney, liver, lung and prostate.
How is the procedure performed?
The procedure stops the blood flowing into the vessels, which causes the nosebleed. It also prevents blood from flowing into the area around the affected vessels. Using X-ray imaging for guidance, a catheter (a long, thin tube) is guided up the femoral artery in the groin to the blood vessel causing the nosebleed. Once in position, an embolizing agent in the form of either small resin particles (known as microparticles), small metal spirals (known as microcoils), a glue-like substance, or some other material, is injected to block the artery and stop the bleeding.
What are the benefits?
- Rapid recovery time with less pain when compared to surgical tumor management.
- Preserves most healthy tissue and is less damaging to surrounding tissue than other methods
- High success in stopping the growth or spread of cancerous cells
