FIG 1.
Sagittal T1-weighted (500/20 [TR/TE]) spin-echo MR image shows hyperintense thrombus in the right transverse and sigmoid sinus.
FIG 2. Posterior/anterior view of the initial venogram from a right, internal jugular injection shows multiple, irregular filling defects in the right sigmoid and transverse sinus consistent with thrombosis.
FIG 3. Posterior/anterior view during thrombectomy catheter placement shows the exchange microwire extending from the right internal jugular vein into the left transverse sinus and the catheter successfully advanced into the torcula beyond the occlusion.
FIG 4. Posterior/anterior view of a follow-up venogram performed from the base catheter in the right internal jugular vein reveals marked improvement with a patent channel through the previously occluded transverse and sigmoid sinus.
FIG 5. Photograph of the AngioJet® catheter. An arrow points to the high-flow input nozzle.
