Use of intra-arterial carbon-dioxide-enhanced ultrasonography for guidance of radiofrequency ablation and transcatheter arterial chemoembolization in hepatocellular carcinoma.
A 73-year-old man with hepatitis-C-related cirrhosis and an elevated alpha-fetoprotein level and tumor in segment 3 of his liver was referred for interventional radiologic treatment. He was not a candidate for surgical resection due to impaired liver function and his personal preferences. On conventional ultrasonography no lesion could be detected, but the tumor was clearly depicted by intra-arterial carbon-dioxide-enhanced ultrasonography. Radiofrequency ablation was performed safely and accurately under the guidance of carbon-dioxide-enhanced ultrasonography. By concomitant performance of transcatheter arterial chemoembolization with radiofrequency ablation, extensive necrosis was obtained and adequate tumor volume reduction achieved with only one treatment session.
