The use of detachable balloons for treating carotid cavernous sinus fistulas is increasing [1-6]. Its success requires exact localization of the fistula site, which may not always be possible with standard angiographic techniques [7]. Rapid opacification of the venous side of the fistula is apt to obscure the point of arteriovenous communication before it is precisely delineated . Rapid filming (four or more films per second), special projections, and subtraction technique are useful adjuncts… CONTINUE READING
