Radiofrequency ablation in a porcine liver model: Effects of transcatheter arterial embolization with iodized oil on ablation time, maximum output, and coagulation diameter as well as angiographic characteristics

Figure 1 Portography revealing occlusion of distal small portal vein branches in the ablated area (arrow) (A) and hepatic arteriography showing a compensatory increase in hepatic arterial blood flow in response to occlusion of the portal vein branches (arrow head) (B) in group with RFA alone.
