Images of a 38-year-old woman with a DCCF; the DCCF was successfully occluded by a detached balloon with patency of the ICA. A, Premature balloon deflation causes recurrent DCCF and drains to the superior ophthalmic vein. Images of a 38-year-old woman with a DCCF; the DCCF was successfully occluded by a detached balloon with patency of the ICA. A, Premature balloon deflation causes recurrent DCCF and drains to the superior ophthalmic vein. Navigation of the additional balloon into the cavernous sinus failed because of blockage by a previously detached balloon (arrow). B and C, One GDC and 0.7 mL of n-BCA mixture were injected into the cavernous sinus under a protective balloon at the cavernous portion of the ICA (arrows), resulting in an angiographic cure of the recurrent DCCF with ICA preservation. Note a small asymptomatic false sac (arrowhead) at the cavernous sinus owing to insufficient NBCA filling. C.-B. Luo et al.
