Two Cases of Cerebral Venous Sinus Thrombosis Successfully Recanalized by the Concomitant Use of an Aspiration through the Guiding Catheter and Stent Thrombectomy Device

Objective: Two cases of cerebral venous sinus thrombosis (CVST) effectively recanalized endovascularly by a combination of thromboaspiration using Cerulean catheter DD6 and stent retriever device are reported. Case Presentations: We endovascularly treated two cases of CVST that presented with progressive vomiting and disturbance of consciousness several days before the diagnosis of occlusion of the main venous sinus and venous congestion. The thrombus was removed by the combined use of an aspiration system made of Cerulean catheter DD6 connected to the Penumbra aspiration pump and a Solitaire FR thrombectomy device. In one case, balloon thrombofragmentation was performed with local thrombolytic therapy. In both cases, the occluded venous sinus was recanalized, venous congestion was resolved, and early initiation of anticoagulation therapy was possible. After the procedure, neurologic symptoms disappeared, and both patients were discharged 16 days after the procedure with a modified Rankin Scale (mRS) score of 0. Conclusion: In CVST, thromboaspiration by the concomitant use of a Cerulean catheter DD6 and a stent retriever is considered an effective therapeutic approach.
