ABSTRACT
<p><b>OBJECTIVE</b>Tentorial dural arteriovenous fistulae are uncommon but life-threatened lesions. We present our experience of 5 cases with tentorial dural arteriovenous fistulae, review the relevant literature and present the rationale of our current management strategy.</p><p><b>METHODS</b>The data of five patients with tentorial DAVF treated in Huashan Hospital between June 2002 and May 2003 were reviewed retrospectively, including their ill history, neuroimagings, operation records and follow-up data.</p><p><b>RESULTS</b>There were 3 females and 2 males with age from 25 to 52 years (average, 42.6 years). Clinical manifestations were acute subarachnoid hemorrhage in 2 cases, progressing neurological deficits in 3 cases. MRI and DSA were major diagnostic and follow-up modalities. Borden classification type II was in 1 case, type III in 4 cases. According to DAVF location, tentorial marginal type were in 3 cases, tentorial lateral type 1 case, tentorial medial type 1 case. Two patients had transarterial embolization preoperatively. All patients underwent craniotomy with the coagulation of the nidus and tentorium, disconnection of leptomeningeal venous drainage. The surgical approaches were via trans-anterior-petrous approach in 3 cases, transpterional subdural approach 1 case, transoccipital and transtentorial approach 1 case. All patients had clinical improvement, there was no surgical mortality and morbidity. Postoperative DSA confirmed obliteration of DAVF in 3 cases, MRI demonstrated the thrombosis of venous aneurysm and the disappearance of previous brainstem edema, partial thrombosis of venous aneurysm in 1 case. Follow-up study ranging from 1 to 2 year showed no recurrence and all patients resume their full activities.</p><p><b>CONCLUSIONS</b>Tentorial DAVF is an aggressive vascular lesion, causing subarachnoid hemorrhage and progressive neurological deficits. Prompt diagnosis and definite treatment for tentorial DAVF are mandatory. Obliteration of the nidus and/or leptomeningeal venous drainage should be the goal of treatment. Microsurgical procedures with/without endovascular intervention are the best choice of treatment.</p>
