title: Abdominal wall necrosis following transcatheter arterial chemoembolization for hepatocellular carcinoma.
abstract: A 76-year-old man, who had inoperable hepatocellular carcinoma, had been treated with transcatheter arterial chemoembolization (TACE) 11 times, percutaneous ethanol injection therapy three times and conformal radiotherapy once, all in other hospitals. At this admission, he developed myocutaneous necrosis in the right abdominal wall after TACE, via the collateral of the right internal mammary artery (IMA). Necrosis of the abdominal wall was due to ischemic changes caused by embolization of the distal branches of the IMA, which were aggravated by previous radiation therapy. We advise that embolization of the IMA in patients who have received radiotherapy should be avoided, if possible.
