Cryoablation is a medical procedure that utilizes extreme cold to effectively destroy abnormal cells within the body. Specifically, in the context of liver tumors, percutaneous liver ablation is a minimally invasive technique that is performed with the assistance of imaging technologies such as ultrasound (US), computerized tomography (CT), or magnetic resonance imaging (MRI). These imaging modalities are crucial as they help in accurately identifying the location and size of the liver tumor(s). During the procedure, a thin, hollow cryoprobe is carefully inserted through the skin and directed to the targeted tumor area. Once in place, liquid nitrogen or argon gas is injected through the cryoprobe, resulting in the freezing of the tumor tissue. This freezing process leads to the destruction of the tumor cells, which are then gradually absorbed by the body, eliminating the need for mechanical removal of the tissue. Cryoablation is particularly advantageous for treating both large and small tumors, especially in cases where traditional open surgical resection is not feasible due to factors such as the patient's age, existing medical conditions, or when the goal is to provide palliative care for patients with systemic disseminated disease.
