A patient with refractory tumors treated by transarterial embolization ablation. A: Limited lipiodol accumulation in a patient with a diffuse hepatocellular carcinoma tumor after transcatheter arterial chemoembolization (TACE) (arrows); B: After a second treatment with TACE, the tumor had progressed and showed less lipiodol accumulation (arrows); C: Hepatic artery angiography showed that tumor staining was not obvious. According to computed tomography images before transarterial embolization ablation (TEA), lipiodol-ethanol mixture was injected through the left and right hepatic arteries; D: Two months after TEA, the tumor had shrunk and lipiodol accumulation had increased (arrows).
