A new embolization agent combining ethanol-estrogen and polyvinyl acetate was evaluated angiographically and histologically in 18 canine renal arterial systems. Peripheral vessels of less than 100 microns diameter were obliterated by thrombus induced by ethanol-estrogen, and larger vessels were obliterated by polyvinyl acetate casts and/or thrombus. This embolization method is easily controlled and has fewer adverse effects, so is suitable for intravascular applications, especially in the head and neck regions.
