Abstract

Renal infarction with ethanol was induced experimentally in rabbits and selective renal angiography was performed to evaluate the effectiveness of ethanol as embolic material. The results were as follows: 1. Complete obstruction of renal artery was produced in all cases within 1 week after injection of absolute ethanol (0.5ml/Kg). 2. Incomplete obstruction of renal artery was produced in majority after injection of absolute ethanol (0.2ml/Kg) and changed to complete obstruction above half cases with time. 3. Incomplete obstruction of renal artery was produced in minority after injection of 60% ethanol (0.2ml/Kg) and complete obstruction of renal artery was not produced. It was considered that ethanol is an effective agent for complete renal infarction and 0.2 to 0.5ml/Kg of absolute ethanol is effective dose for complete renal infarction.
