Definition and Basic Principles Cryosurgery involves the application of extreme cold to target tissues with the goal of destruction or removal. The process typically uses substances like liquid nitrogen, argon gas, or carbon dioxide to achieve temperatures ranging from -20°C to -196°C. These cold temperatures induce cellular destruction primarily through ice crystal formation within cells, leading to cell membrane rupture, and through vascular injury that causes ischemia and subsequent tissue necrosis. Mechanism of Action The effectiveness of cryosurgery depends on several mechanisms: Ice Crystal Formation: Rapid freezing causes intracellular and extracellular ice crystals that puncture cell membranes. Vascular Damage: Freezing damages blood vessels supplying the tissue, leading to ischemia and necrosis. Reperfusion Injury: Upon thawing, the damaged tissue undergoes inflammatory responses that assist in tissue destruction. Common Techniques and Devices Different methods and devices are used, including: Liquid Nitrogen Spray: Used for superficial lesions, applied directly via spray or1. probe. 2 Cryoprobes: Invasive probes inserted into deeper tissues, often guided by imaging2. modalities.
