PERCUTANEOUS INTRAVASCULAR ETHANOL INJECTION OF THE SUPPLYING TUMOR VESSEL IN THE TREATMENT OF HEPATOCELLULAR-CARCINOMA LARGER THAN 3 CM

Percutaneous intravascular ethanol injection of the supplying vessel o f the tumor using color Doppler imaging was performed in three patient s (three lesions) with hepatocellular carcinoma measuring more than 3 cm. Intravascular injection was achieved in six out of seven attempts. The total amount of ethanol injected intravascularly was small (10, 1 5, and 26 ml for each patient). One attempt (4 ml) failed and the etha nol was injected perivascularly. No serious complication was noted. Af ter treatment, two patients showed remarkable decrease in tumor size a nd one showed massive tumor necrosis. In conclusion, ethanol injection using the intravascular approach may be of value in the palliative ma nagement of large hepatocellular carcinomas.
