Stenting of the dural venous sinuses has emerged as a therapeutic option for intracranial hypertension and pulsatile tinnitus. However, venous endovascular navigation faces challenges due to lower-quality roadmaps compared to arterial navigation. This study explores the application of three-dimensional (3D) rotational venography in assessing the cerebral venous vasculature and its potential for venous navigation. The methods involve venous 3D digital subtracted angiography (DSA) in patients with dural venous stenosis, with image acquisition using a biplane angiographic system. The results highlight the enhanced spatial resolution of 3D venous imaging, providing anatomical information crucial for precise characterization of stenosis and understanding cortical venous drainage. 3D venous roadmapping is shown to improve endovascular venous navigation, offering synchronized and rotatable 3D roadmaps, providing a comprehensive approach to optimize endovascular venous interventions.

3D 数字减影血管造影静脉路线图用于硬脑膜静脉狭窄的血管内治疗

硬脑膜静脉窦支架植入术已成为颅内高压和搏动性耳鸣的一种治疗选择。然而，与动脉导航相比，静脉血管内导航由于路线图质量较低而面临挑战。本研究探讨了三维（3D）旋转静脉造影在评估脑静脉血管系统及其静脉导航潜力中的应用。该方法涉及对硬脑膜静脉狭窄患者进行静脉 3D 数字减影血管造影 (DSA)，并使用双平面血管造影系统采集图像。结果凸显了 3D 静脉成像空间分辨率的增强，为精确表征狭窄和了解皮质静脉引流提供了至关重要的解剖信息。3D 静脉路线图显示可以改善血管内静脉导航，提供同步且可旋转的 3D 路线图，从而提供优化血管内静脉干预的综合方法。
