A Patient with Severe Cerebral Sinus Thrombosis in Whom Mechanical Thrombolysis with a Balloon and Thrombectomy with a Stent Retriever Were Effective

抄録

Objective: We report a patient with severe cerebral sinus thrombosis (CST) in whom mechanical thrombolysis with a balloon and thrombectomy with a stent retriever were effective.

Case Presentation: The patient was a 32-year-old male. Headache occurred, and magnetic resonance venography (MRV) showed occlusion of the superior sagittal sinus. Transvenous anticoagulant therapy was performed, but consciousness disorder and paralysis progressed in a few days. Head CT revealed marked edema of the bilateral frontal lobes and cerebral hemorrhage. Cerebral angiography showed occlusion of the superior sagittal sinus, and endovascular treatment with a balloon and stent retriever was performed, leading to recanalization. Finally, the course was favorable.

Conclusion: Endovascular treatment with a stent retriever may be safe and effective for severe CST.
