Transhepatic approach for percutaneous computed-tomography-guided radiofrequency ablation of renal cell carcinoma.
We performed percutaneously radiofrequency (RF) ablation of 5 renal cell carcinomas (mean diameter 26 +/- 15 mm) with computed-tomography (CT) fluoroscopic guidance using the transhepatic route. The RF electrode was successfully advanced into all tumors. RF ablation caused one minor complication (small asymptomatic perirenal hematoma); no major complications occurred. The follow-up contrast-enhanced CT images showed no local tumor progression of any tumors in a median period of 10 months (range 3-14 months). In conclusion, it seems that this transhepatic approach is safe and can be an alternative method for electrode insertion during RF ablation of selected renal tumors.
