Results : The distance between knee of transverse sigmoid sinus and posterior border of internal acoustic porus was ( 35.1 ± 0.2 ) mm .

结果经静脉入路治疗横窦-乙状窦区DAVF共16例。病变累及横窦-乙状窦交界处者11例、横窦者3例、乙状窦者2例。

Results Sixteen patients with transverse-sigmoid sinus DAVF were treated by transvenous approach .

结论对于适当选择的横窦-乙状窦区DAVF病例，经静脉入路闭塞病变静脉窦是一种安全有效的治疗方法。

Conclusion In properly selected cases , transvenous occlusion of the DAVF involved transverse-sigmoid sinus was safe and efficient .

目的评价经静脉入路栓塞治疗横窦-乙状窦区硬脑膜动静脉瘘（DAVF）的安全性和有效性。

Objective To evaluate the safety and the efficacy of transvenous embolization of transverse-sigmoid sinus dural arteriovenous fistula ( DAVF ) .

病变组乙状窦前位（32.3%）发生率高于正常对照组（15.8%，P0.05），气化不良组（43.5%）高于气化良好组（11.3%，P0.05）。

The incidence of ante-rior location of sigmoid sinus in the abnormal group ( 32.3 % ) was higher than that in normal group ( 15.8 % ), which was higher in poorly pneumatized group ( 43.5 % ) than that in well pneumatized group ( 11.3 % ) .

静脉对神经根有压迫的占15.4%；③岩静脉距横窦与乙状窦交角处的距离为31.1±5.2mm。

The distance from the petrosal vein to the meeting point of the transverse and sigmoid sinuses was 31.1 ± 5.2 mm .

直径小于1cm的听神经瘤，经中颅凹入路和乙状窦后入路切除肿瘤均可，但中颅凹入路术野开阔，利于手术操作；

To acoustic tumors less than 1 cm in diameter , both of the middle cranial fossa approach and retrosigmoid approach can be used , but the middle cranial fossa has broad vision , it is helpful to operate .

磨除部分乳突后联合颞部开颅，形成一3.5cm×3cm大小的骨窗，暴露并剪开乙状窦前和颞部硬脑膜，牵开颞叶和小脑半球，显微镜下观察所显露的解剖结构。

After stripping partial mastoid process , a 3.5cm × 3cm bone window at the temporal part was made to expose the anterior part of the sigmoid sinus and temporal dura mater . Many anatomic structures can be observed under microscope when cerebellar hemisphere and temporal lobe were drawn away .
