Figure 4:

A vascular cooling effect could be observed around the vessel in all ablations of the test series without Pringle maneuver (V₄).

However, this cooling effect was not significant (p>0.05). An increase of ablation area could be observed on the margin of the ablations in the test series with intermittent Pringle maneuver, starting without hepatic inflow occlusion (V₁–V₃). In between 2.5 and 10.0 mm (“~”), no change in ablation area could be observed between the five test series (*, significant; ns., not significant; p>0.05).
