What is Argon-Helium Cryoablation?

Argon-Helium Cryoablation is minimally invasive, simple, and convenient. Its clear ablation boundaries make it easy for doctors to determine the ablation boundaries, significantly improving safety.

However, the Cryoablation with Argon-Helium Cryoablation is not a real knife, but a special puncture needle.

Cryoablation with Argon-Helium Cryoablation uses argon and helium gases to rapidly cool diseased tissue and destroy cells. And then, as the frozen tissue is warmed up, the ice crystals formed by the low temperature quickly melt. Water enters the cells due to the osmotic pressure difference between the inside and outside of the cells, causing tumor cells to swell and rupture, resulting in secondary cell destruction. In simple terms, cryoablation involves creating extremely low temperatures, freezing tumor cells and then dissolving them, thereby killing the cancerous cells. It also damages the tumor's microvasculature, halting blood supply and causing further apoptosis and necrosis.

What are the advantages of argon-helium cryoablation?

As a minimally invasive treatment, argon-helium cryoablation is minimally invasive and has minimal impact on organ function. Patients generally recover faster, which significantly shortens their hospital stay.

It also offers the advantages of tumor ablation: precision, safety, effectiveness, minimal invasiveness, amenability to repeated treatments, ease of use, low cost, minimal patient pain, and a high quality of life after surgery.

Notably, argon-helium cryoablation also has immunomodulatory effects, activating host cells' anti-tumor immunity and enabling them to eliminate diseased and necrotic cells.

When to apply argon-helium cryoablation?

It is generally believed that cryoablation can ablate almost all solid malignant tumors, such as liver cancer, lung cancer, head and neck tumors, breast cancer, pelvic tumors, bone tumors, and kidney tumors. This is particularly true for patients who are reluctant to undergo surgery, the elderly and frail, those who have lost the opportunity for surgery, and those with recurrent or metastatic tumors.

In addition, clinical findings indicate that frozen cancer cells are more sensitive to chemotherapy and radiotherapy, enhancing their effectiveness and improving lesion control. Therefore, cryoablation is often combined with radiotherapy and chemotherapy to achieve better therapeutic outcomes.
