What happens to the tumor after cryoablation?
Cryoablation of the tumour tissue results in cell destruction by freezing. Contrary to heat-based ablative modalities, cryoablation induces tumour cell death by osmosis and necrosis.
What are the side effects of cryoablation?
Cryoablation is generally very well-tolerated by patients, and most do not experience any significant side effects. Rare side effects include stomach, chest, or throat pain, bleeding, perforation, or ulcers. Cryoablation is a minimally-invasive procedure that does not require any incisions.
How is cryotherapy performed?
During cryotherapy, liquid nitrogen or high-pressure argon gas flows into a needle-like applicator or cryoprobe. This creates intense cold that the doctor uses to freeze and destroy diseased tissue.
Does cryosurgery hurt?
Cryotherapy is painful. A numbing local anesthetic is usually not needed but may be used in some cases.
How long does cryosurgery take to heal?
The treated area will heal in about 7 to 10 days. It probably won’t leave a scar.
What is the success rate of cryoablation?
The cancer-specific survival rate was 100%, and the cancer-free survival rate after a single cryoablation procedure was 87.5%. This improved to 97.5% after a repeat procedure. No major complications were observed.
How effective is cryoablation?
All studies showed that cryoablation during concomitant surgery had a significant effect on return to sinus rhythm (SR) conversion rate. One study showed that cryoablation was significantly more effective than mitral valve surgery alone at a 12-month follow-up (73.3% vs. 42.9%, respectively, P=0.013).
Which type of tumor would most likely be treated with cryoablation?
Cryoablation is usually effective for localized kidney cancer and some liver and lung cancers. Cryoablation spares healthy kidney tissue and can be repeated, if needed. Most patients go home the same day.
What should I expect after cryoablation?
In the days after the procedure, you may experience mild symptoms such as an achy chest and discomfort, or bruising in the area where the catheter was inserted. You might also notice skipped heartbeats or irregular heart rhythms. Most people can return to their normal activities within a few days.
How can I speed up healing from cryotherapy?
This involves cleaning the treated area with soap and water. You can do this at least twice a day. Also, you can use antibiotic ointments or petroleum jelly to speed up the healing process.
