Abstract

Transcatheter embolization using absolute ethanol is a widely used technic in interventional radiology. Butits mechanism of action and embolization effect on various infusion speed are poorly understood. Authors performedan experimental study in rabbits to doccument the effect of absolute ethanol onvarious infusion rate. The resultsare as follows; 1. In high speed infusion group(>0.1ml/sec. n=13), 11 cases showed peripheral obstruction and 2 cases showed central obstruction. 2. In low speed infusion group(<0.1ml/sec. n=12), 4 cases showed peripheralobstruction and 8 cases showed central obstruction (p<0.02). 3. On follow-up angiography performed 4 weeks later(n=8), no demonstrable significant differences are found between two groups.
