【Abstract】 Objective To study the way and effect of endovascular regional thrombolysis treatment of severe dural venous sinus thrombosis. Methods The experiences in 6 patients with severe dural venous sinus thrombosis treated in our hospital since 2 000 were summarized. Four cases had been treated by transfemoral arterovenous approach and 2 cases by femoral artery and superior sagittal sinus approach. 5 French catheter was positioned in the internal carotid artery and 3/2.5 French microcatheter inside the dural venous sinus thrombosis. After 500 000 U urokinase had been injected into the internal carotid artery and the thrombosis respectively by 10 000 U per minute, urokinase was injected into the thrombosed sinus continuously and fibrinogen was maintained at 1.0-1.5 g/L. The activated partial thromboplastin was retained at twice or three times longer than the standard by systemic anticoagulation with heparin. Results 5 of the 6 cases were cured. DSA was normal in the superior sagittal sinus and cortical veins in 4 cases, and DSA was improved in cortical veins and dural venous sinus in 1 case. One of the 6 cases was markedly improved, and DSA was normal in the superior sagittal sinus and cortical veins, and it was cured by anticoagulation treatment after one month. Conclusion Endovascular regional thrombolysis treatment of severe dural venous sinus thrombosis is effective, safe, and prompt. If it is difficult to position the catheter in thrombosed dural venous sinus by transfemoral venous approach, transsuperior sagittal sinus approach is a simple, effective, and cheap alternative.更多还原
