Endovascular mechanical thrombectomy using a stent retriever and an aspiration catheter in three cases of severe cerebral venous sinus thrombosis

Abstract

  We report three consecutive cases of severe cerebral venous sinus thrombosis treated with an endovascular mechanical thrombectomy using a stent retriever and an aspiration catheter. (1) A 76‒year‒old man presented with headache and left hemiparesis and subsequently developed status epilepticus. (2) A 57‒year‒old woman presented with impaired consciousness. (3) A 30‒year‒old man presented with headache and progressive deterioration of consciousness. In all three cases, diagnostic imaging revealed thrombosis of multiple cerebral venous sinuses, including the superior sagittal sinus and bilateral transverse sinuses. After an endovascular mechanical thrombectomy with a stent retriever, all three patients recovered without severe neurological deficits. Endovascular mechanical thrombectomy is an effective method for achieving early recanalization and thus improving the clinical and radiological outcomes of patients with severe cerebral venous sinus thrombosis. Although the accumulation of more cases is needed, a stent retriever and an aspiration catheter appear to be safe and effective devices for endovascular thrombectomy.
