What is Cryoablation?
Your healthcare provider has requested that you undergo cryoablation treatment. You have been diagnosed with having a tumor. Cryoablation is a treatment that kills cancer cells with extreme cold. It is often recommended when traditional surgical resection isn't the best option.
How Should I Prepare?
You should not eat or drink anything for six hours prior to your procedure. You may take your medications as directed. Speak to your doctor if you need to adjust your insulin dosing. Prior to your procedure, you should make sure all medications and allergies are updated. If you are on a blood thinner you may be requested to stop that medication for a period of time.
How is the Procedure Performed?
The procedure will be performed by an interventional radiologist, who is a physician with specific training in image-guided procedures. Most cryoablation procedures are performed under general anesthesia.
The site for the ablation treatment will be evaluated using CT, ultrasound or other imaging. The overlying skin will be cleaned with sterilizing solution. A wand-like device is then advanced into the tumor. A gas is used to freeze the targeted tissue, and then the tissue is then allowed to thaw. Upon completion, the device is removed and a sterile dressing placed at the site.
What Should I Expect After the Procedure?
Following the procedure, you will be monitored in the hospital, and any medications you need to ensure you are comfortable will be provided. Most patients are admitted to the hospital for overnight observation.
Who Interprets the Results?
In order to assess how the treatment affected the tumor, you will have additional imaging performed in 1-6 months.
