Cryoablation is a procedure that uses excessive cool (Cryo) to get rid of or harm cells (ablation). It is used in a wide range of medical programs using empty small needles (cryoprobes) through which chilled, thermally conductive, liquids are distributed. Cryoprobes are placed into or placed nearby to cells, which is identified to be diseased in such a way that ablation will benefit and ablate the cancereous cells..
The most popular use of cryoablation is to ablate strong cancers found in the bronchi, liver, breasts, kidney and prostate. Cryoablation in often used in prostate and kidney cancer. Although sometimes used through laparoscopy or open medical techniques, most often cryoablation is conducted percutaneously (through the skin and into the focus on cells containing the tumor) by an Interventional radiologist.
When to use cryoablation ?
Cryoablation may be used to treat cancer when surgery treatment isn't an option. Cryoablation is sometimes used as a main therapy for:
- Bone tissue cancer
- Cervical cancer
- Eye cancer
- Kidney cancer
- Liver cancer
- Carcinoma of lungs
- Endocrine cancer
Cryoablation is also used to alleviate the pain and other signs due to melanoma that propagates to the bone tissues (bone metastasis) or other body parts
What happens during Cryoablation?
During ablation process, a condensed refrigerant, fluid nitrous oxide (N2O), is provided from an aquarium in the CryoConsole. The fluid refrigerant moves in an ultra-fine pipe through the coaxial umbilical and the base of the Freezor CryoAblation Catheter to the tip of the catheter.
The fluid refrigerant vaporizes as it is applied into the tip. As it vaporizes, it takes up warmth from the nearby cells. The focus is on chilling t he cells. The heated refrigerant is cleaned returning to the CryoConsole through a lumen within the base of the catheter and coaxial umbilical. The CryoConsole discharges the steam into the medical center scavenging program.
Freezer can make temperature ranges at its tip as low as -75ºC. Cryomapping may aid doctors to prevent undesirable electrophysiological results on AV node transmission.
When you go back house after the process, do the following to help make sure a simple recovery:
- Take pain killers as suggested. It is often suggested for 2-4 several weeks. This will help to prevent clog development at the ablation sites.
- Return to any regular mild actions, such as strolling or taking the steps. Avoid from hard work or any intense action for Twenty four times. In many instances, you will be able revisit your regular activity level within a few days.
- It is recommended to schedule a follow-up check up with your physician.
