Cutaneous complications of hepatic chemoembolization via extrahepatic collaterals.
PURPOSE: To report cutaneous complications occurring after chemoembolization of hepatic tumors via extrahepatic collaterals. METHODS: Five patients underwent chemoembolization via the internal mammary (n = 3), intercostal (n = 1), or multiple extrahepatic collateral vessels supplying liver metastases. RESULTS: Painful induration and discoloration of the skin in the distribution of the superior epigastric or intercostal arteries occurred in four patients, with transmural necrosis in two. One required surgical excision. One patient developed a radiation burn after 12 procedures and eventually developed a squamous cell carcinoma at the site, which required resection and skin grafting. CONCLUSION: Cutaneous injury can occur after chemoembolization of extrahepatic collaterals. Scrupulous technique is required to avoid nontarget embolization of chemotherapeutic drugs. High cumulative radiation doses to localized areas of skin can occur in patients undergoing multiple procedures.

Minimally invasive treatment of malignant hepatic tumors: at the threshold of a major breakthrough.
Six existing minimally invasive techniques for the treatment of primary and secondary malignant hepatic tumors--radio-frequency ablation, microwave ablation, laser ablation, cryoablation, ethanol ablation, and chemoembolization--are reviewed and debated by noted authorities from six institutions from around the world. All of the authors currently believe that surgery remains the treatment of choice for patients with resectable hepatic tumors. However, the clinical results of each of the minimally invasive techniques presented have exceeded those obtained with conventional chemotherapy or radiation therapy. Thus, for nonsurgical patients, these techniques are becoming standard independent or adjuvant therapies. In addition, with continued improvement in technology and increasing clinical experience, one or more of these minimally invasive techniques may soon challenge surgical resection as the treatment of choice for patients with limited hepatic tumor.
