What is percutaneous cryoablation?
In percutaneous cryoablation, no large incisions are made. Instead, an interventional radiologist inserts a thin, needle-like probe through the skin and into the tumor, using advanced imaging technology for guidance. This technique helps avoid larger incisions that are associated with cryoablation during traditional open surgery or minimally invasive laparoscopic surgery.
How does cryoablation work?
Depending on the tumor's size, one or more probes are inserted into the tumor. Pressurized gas is pumped to a chamber at the needle's tip, where it expands then cools, creating an ice ball chilled to minus 160 degrees Celsius. The ice ball engulfs and destroys the tumor while sparing healthy tissue. Ultrathin sensor needles also are inserted at the tumor's margins to monitor temperatures and ensure that all the cancerous tissue is destroyed.
What kind of cancer do the cryoablation can treat?
Cryoablation is performed by using argon-helium system. Two to three cycles of the freezing/thawing are performed. The freezing continues until the "ice-ball" formed at the tip if the cryoprobe is large enough to cover tumor. A 5-10 mm margin of normal tissue is included in the freezing process. For larger tumors, multiple cryoprobes were used. In some cases, it may become necessary to perform at least 2-3 sessions of the cryoablation procedure. This is possible because the procedure is minimally invasive, and often does not require cutting. The probes are simply inserted through the skin and guided by real-time ultrasound.
