Core Tip

Core Tip: This is a basic experimental research paper on the heat irrigating effect of radiofrequency ablation (RFA). To determine the influence of the heat irrigating effect of RFA on the regional liver tissue in Bama miniature pigs, we designed a series of research experiments. We found changes due to thermal damage in the liver tissue around the ablated portal vein and its distal area as a result of the heat irrigating effect when the RFA electrode tip was close to (< 5 mm) the portal vein.
