title: Percutaneous alcohol injection of portal thrombosis in hepatocellular carcinoma: a new possible treatment.
abstract: Hepatocellular carcinoma (HCC) with portal thrombosis is usually regarded as a contraindication for surgery and for percutaneous alcohol injection (PAI). For palliative purposes we used PAI in 4 patients with infiltrative HCC and segmental portal thrombosis. Ethanol, injected directly into the thrombus, diffused mostly along it. No complications emerged after 20 injections. In the first patient, who later received a liver transplant, the thrombus was completely necrotic. In the other patients, biopsies yielded only necrotic material: in two cases, progression of the thrombus was stopped at 4 and 12 months of follow-up, and in one case the thrombus shrank and remained as such 13 months later. This preliminary experience might broaden the scope of treatment for HCC.
