Abstract

<p>Objective: We report three patients successfully treated by emergent transvenous thrombectomy for cerebral venous sinus thrombosis (CVST).</p><p>Case Presentation: (Case 1) A 77-year-old man presented with vomiting, dizziness, and headache. CT revealed local subarachnoid hemorrhage (l-SAH), and angiography confirmed occlusion of the right transverse sigmoid sinus and superior sagittal sinus (SSS). Emergent transvenous aspiration thrombectomy using a Penumbra catheter (PC) resulted in effective reperfusion. (Case 2) A 60-year-old man developed disorientation, sensory aphasia, and right hemiparesis. MRI demonstrated extensive cerebral edema caused by venous congestion in both thalami, and angiography revealed poor opacification of the SSS, straight sinus, and bilateral transverse sinuses. Venous sinus flow was restored by catheter aspiration using a PC and topical infusion of urokinase (UK). (Case 3) A 19-year-old man developed a headache, numbness of the right upper limb, motor paralysis, and convulsions. CT revealed l-SAH and dense clot sign in the SSS. The SSS was poorly delineated on angiography. Thrombus aspiration using a PC and topical UK administration achieved partial recanalization.</p><p>Conclusion: Transvenous aspiration thrombectomy using large lumen catheters for patients with CVST is effective and safe. In particular, this method may be a better option than anti-coagulation therapy alone for patients presenting with a severe neurological condition or intracranial hemorrhage.</p>
