Název v původním jazyce

Temporary liver blood outflow occlusion increases effectiveness of radiofrequency ablation in liver parenchyma. an experimental study

Popis výsledku v původním jazyce

Heat loss induced by tissue vascular flow is one factor limiting radiofrequency tumor ablation (RFA) in the liver parenchyma. Decreasing the liver blood flow appears to be an interesting adjunct to RFA. It seems that manipulation of the portal blood inflow is the most important. However, the percutaneous portal vein occlusion is technically difficult. Complete blockage of the liver blood outflow (LBFO) by occluding the whole segment of the retrohepatic vena cava and its impact on RFA is not experimentally verified. The aim is to evaluate the feasibility of liver blood outflow occlusion and its impact on the effectiveness of RFA. The experiment was performed on 10 pigs. The animals were divided into groups A and B according to RFA protocol. In group A (n = 5) the RFA time was that taken to reach the target temperature of 105 oC, whereas group B (n = 5) had a constant RFA temperature of 105 oC and constant time of 8 min. The liver blood flow (LBF) was quantified using Doppler ultrasonogr
