Transcatheter infusion of absolute ethanol was applied clinically in 3 cases of artificial embolization:
25 yrs old female with bilateral renal angiomyolipoma , 19 yrs old female with right paralumbar liposar'
coma and 25 yrs old male with hypernephroma óf right kid ney. Selective o r subselective manual infusion
was made and 9 to 22cc of pure ethanol was delivered in a speed of 1 to 2cc per second . The sclerosing
effect of absolute ethanol was potent. However, all 3 cases revealed mild post.embolization
syndrome.
