  		FIG 1. 58-year-old woman with left planum sphenoidal meningioma undergoing preoperative temporary balloon occlusion test with the NDSB system.

A, Digital radiograph, arterial phase, during left CCA injection, shows neovascular tumor blush above planum sphenoidal and mild depression and narrowing of the supraclinoid ICA segment, indicating partial vessel encasement by tumor, also apparent by MR imaging.

B, Digital radiograph, arterial phase, during left CCA injection after inflation of NDSB (arrows) in cavernous ICA segment, shows prominent retrograde collateral opacification of the ophthalmic artery, supraclinoid ICA, and contribution to MCA flow.

C and D, Sequential digital radiographs, mid and late arterial phase, during left CCA injection after inflation of NDSB (arrows, C) in ophthalmic segment of left ICA, show successful exclusion of retrograde ophthalmic artery contribution (arrows, D) to the left ICA circulation.
