Brief Summary
Bilateral transverse sinus stenosis (BTSS) is associated with intracranial hypertension (IH). However, not every BTSS patients presented with IH. The risk factors of IH in BTSS patients remained obscure. Vertebral venous collaterals (VVC) were often found in patients with bilateral transverse sinus stenosis (BTSS). The purpose of this study was to investigate the physiological role of VVC in BTSS patients.

normal controls with VVC
SHAM COMPARATORBTSS was confirmed by two of magnetic resonance venography (MRV), computed tomography venography (CTV) or digital subtraction angiography (DSA). The index of TSS (ITSS) score was a useful tool for the assessment of BTSS severity. The degree of stenosis was graded from 0 to 4 based on the following scale: 0 = normal; 1 = stenosis up to 1/3; 2 = stenosis between 1/3 and 2/3; 3 = stenosis \>2/3; and 4 = hypoplasia. ITSS was calculated as degree of right TSS × degree of left TSS. Vertebral venous collaterals (VVC) were found.

Interventions
Subjects underwent a standard lumbar puncture to measure the intracranial pressure (ICP). ICP was measured invasively through lumbar space in the morning.
