Balloon occlusion of carotid-cavernous fistula: introduction of a new catheter.

The most widely used technique for treatment of a carotid-cavernous fistula involves embolization of the fistula with segmental occlusion of the internal carotid artery. An inflatable balloon capping a small flexible catheter becomes a controlled embolus when positioned within the internal carotid artery at the stoma of the fistula. A new double lumen catheter has been designed. Through one lumen the carotid circulation may be displayed, The second lumen allows inflation of the balloon through a self-sealing valve. In twelve patients, results were excellent in eight, fair in two, and poor in two patients intolerant of carotid occlusion.
