ABSTRACT
We have reported two patients in whom absolute ethanol was used to sclerose arteriovenous malformations. Because of its low viscosity, liquid form, and devastating effect when injected intra-arterially, absolute ethanol is effective in treating AVMs, and it has been proven to have curative potential. For these same reasons it is also potentially harmful, particularly to nerves and possibly to skin.

In our experience, clotted angiographic catheters pulled back to near the puncture site and severed near the skin will spontaneously clear, facilitating insertion of a guidewire and catheter exchange without repuncture or other manipulation.

A method for replacing biliary tract catheters with angiographic techniques is described, along with clinical experience in its use. Situations which at first seem hopeless may in fact be simply resolved as in the first instance. We found the fiberoptic scope to be useful when the cannulation tract involves a segment of bowel.
