The management of the internal carotid artery remains difficult when massive skull base lesions must be approached surgically. A detachable balloon catheter (Mini-balloon Detachable Balloon System, Becton-Dickinson, Rutherford, N.J.) has proved helpful in assessment of the collateral circulation of the internal carotid system and in distal control of this vessel when planned ligation is deemed necessary. In conjunction with standard percutaneous catheterization techniques, selective occlusion of blood vessels can be accomplished. The detachable balloon system consists of a silicone rubber balloon attached to a radiopaque, polyurethane catheter. A delivery system has been developed that propels the balloon catheter through a previously placed angiographic catheter into the specific circulation to be embolized.
