Rheolytic Catheter Thrombectomy, Balloon Angioplasty, and Direct Recombinant Tissue Plasminogen Activator Thrombolysis of Dural Sinus Thrombosis with Preexisting Hemorrhagic Infarctions

Anteroposterior projection superior sagittal sinus venogram obtained via the AngioJet catheter port shows considerable improvement with sinus patency. Extensive filling defects from residual thrombus are present in the superior sagittal, right transverse, and right sigmoid sinuses (arrows). In real time, the antegrade flow was subjectively slow. Transosseous collateral veins are also seen (arrowhead).

Anteroposterior projection venogram obtained after rheolytic thrombectomy and while the AngioJet catheter was withdrawn from the left to the right jugular bulb. Multiple filling defects, representing considerable residual thrombus, are seen in both transverse and sigmoid sinuses (arrows). Prominent collateral veins (arrowheads) in the posterior neck are seen aiding venous drainage of the posterior fossa.
