目的：通过脑静脉造影和测压确定特发性颅内高压患者先前证实的上级矢状窦和近端横窦静脉高压的原因。方法：在C1-2穿刺前和穿刺后即刻测定脑静脉窦压力，抽取20 ~ 25 mL脑脊液。结果：测压时经侧颈1 -2穿刺降低颅内压，静脉高压立即消失。结论：这些研究表明，静脉高压是由于颅内压升高对横窦的压迫，而不是由于脑静脉窦中的原发性阻塞过程。
Objective: To determine by cerebral venography and manometry in patients with idiopathic intracranial hypertension the cause of the previously demonstrated venous hypertension in the superior sagittal and proximal transverse sinuses. Methods: Cerebral venous sinus pressure was measured before and immediately after C1-2 puncture with removal of 20 to 25 mL of CSF. Results: Lowering the intracranial pressure by lateral C1-2 puncture during manometry has shown that the venous hypertension resolves immediately. Conclusion: These studies indicate that the venous hypertension is due to compression of the transverse sinuses by raised intracranial pressure and not due to a primary obstructive process in the cerebral venous sinuses.
