摘　　要：小脑幕硬脑膜动静脉瘘(TDAVF)是硬脑膜动静脉瘘的少见类型,临床危害性大。TDAVF可表现为丘脑、小脑、脑干、脊髓受累的急进性神经功能障碍,诊断困难,容易误诊。静脉引流区域血管源性水肿伴出血、异常血管流空影、静脉窦不显影对TDAVF诊断有提示意义。TDAVF确诊依靠DSA,及时手术是良好预后的关键。作者回顾性分析3例TDAVF的临床资料,总结临床特征,分析误诊原因,分享诊疗经验。Although a rare type of dural arteriovenous fistula,tentorial dural arteriovenous fistula(TDAVF)can cause great clinical harm.TDAVF can be characterized by progressive neurological dysfunction caused by thalamus,cerebellum,brain stem and spinal cord damage.TDAVF is difficult to diagnose and easy to be misdiagnosed.Angiogenic edema with hemorrhage in venous drainage area,flow void phenomena and no sign of venous sinus are helpful for its diagnosis.The diagnosis depends on DSA.Timely operation is the key to a good prognosis.The authors retrospectively analyzed the clinical data of 3 patients with TDAVF,summarized the clinical characteristics,analyzed the causes of misdiagnosis,and shared the experience of diagnosis and treatment.
