Transarterial embolization ablation of hepatocellular carcinoma with a lipiodol-ethanol mixture

Figure 1 A newly diagnosed patient with single-nodule treated by transarterial embolization ablation. A: An enhanced computed tomography (CT) scan of hepatocellular carcinoma tumor before treatment. The tumor measured 3.5 cm × 3.3 cm (arrows); B: Hepatic artery angiography showed the thick blood vessels of the tumor (arrowheads) and the abnormal vascular group (arrows) before treatment; C: Superselective angiography clearly showed tumor staining (arrows); D: After transarterial embolization ablation with an lipiodol-ethanol mixture, lipiodol accumulated in the tumor (arrows); E: An enhanced CT scan 2 mo after treatment showed dense deposition of lipiodol in the tumor without enhancement (arrows); F: Hepatic artery angiography showed the absence of tumor blood vessels and tumor staining at 2 mo after treatment (arrows).
