Résumé

Percutaneous microwave ablation is an effective and minimally invasive treatment for small tumors. To achieve local disease control, the entire tumor and a surrounding safety margin must be destroyed. Power and application time are chosen based on manufacturer-provided data, usually obtained from ex vivo animal models. However, ex vivo tissues differ from in vivo condition due to compositional changes and absence of heat dissipation by blood flow. This study aimed to compare in vivo ablation zone sizes in swine with those predicted by the device manufacturer.
