Oblique frontal angiogram (A) demonstrates segmental visualization of the SSS and no significant opacification of the right TS and proximal SS because of DVST (arrows). Balloon thrombectomy (B, C) of the SSS and right TS was performed, and after 5 days of intrasinus heparin infusion, a frontal angiogram (D) demonstrates near-complete flow restoration with only minimal residual filling defect (arrows; D) in the right TS.
