Which statement is true about cryoadherence in cryoablation?

The statement that cryoadherence results in very focal lesions is accurate. In cryoablation, cryoadherence refers to the phenomenon where the tissue adheres to the cryo probe due to the freezing process. This relationship between the cryo probe and the target tissue enables very precise localized treatment. By exerting control over the ablation area, clinicians can create well-defined lesions that effectively target the problematic tissue without affecting surrounding healthy structures. This focal nature of the lesions is a key advantage in many medical applications, particularly in interventions like treating tumors or cardiac arrhythmias, where targeting the exact cells is crucial for success.

Broad lesions typically result from different energy sources or techniques that might not focus the thermal effect tightly enough, while managing pain perception can involve various factors not solely reliant on cryoadherence. Furthermore, cryoadherence is often considered an important aspect for achieving effective ablation, rather than being unnecessary. Therefore, the potential for creating very focused lesions through cryoadherence in cryoablation stands out as a significant benefit of the technique.
