Figure 3.

A nine-year-old boy with multiple dural arteriovenous fistulas at superior sagittal sinus and bilateral transverse-sigmoid sinuses. Bilateral transverse-sigmoid sinuses were occluded. After three sessions of intervention, entire superior sagittal sinus, bilateral transverse-sigmoid sinuses, and straight sinus were occluded with coils, and dural arteriovenous fistulas are almost occluded. Normal venous drainages of left cerebral hemisphere were through the prominent left superficial middle cerebral veins and left trans-striatal route (arrow) to the cavernous sinus. (a) Left internal carotid angiogram (lateral view, venous phase). (b) Three-dimensional rotational angiography of left internal carotid injection (lateral view, venous phase). (c) Three-dimensional rotational angiography of left internal carotid injection (lateral view, venous phase, superficial veins are removed manually). Arrow indicates trans-striatal route collecting enlarged deep medullary venous flow (arrowheads).
