“…Moreover, one right-sided or left-sided, or total absence of the occipital sinus has been reported [15]. It may also communicate with other sinuses and veins, including superior sagittal, straight, transverse, or sigmoid sinuses, or the superior jugular bulb [39]. By this wide range of communication, it has been reported that occipital sinus may play a significant role as a collateral course in case of other sinuses disease or occlusion.…”

“…Blood flow through enlarged dural veins in superior sagittal sinus occlusion has been demonstrated, and may represent one collateral path. 24 Two additional paths include the vein of Labbe 25 (a cortical vein that drains the lateral surface of the hemispheres) and the occipital sinus 26 (draining directly from the torcular). Both of these structures can, albeit with variation, drain into the sigmoid sinus, bypassing the distal TS where the majority of stenoses in patients with IIH occur.…”

Objective: Transverse sinus stenosis (TSS) is common in idiopathic intracranial hypertension (IIH), but its effect on the course and outcome of IIH is unknown. We evaluated differences in TSS characteristics between patients with IIH with "good" vs "poor" clinical courses.Methods: All patients with IIH seen in our institution after September 2009 who underwent a high-quality standardized brain magnetic resonance venogram (MRV) were included. Patients were categorized as having a good or poor clinical course based on medical record review. The location and percent of each TSS were determined for each patient, and were correlated to the clinical outcome. Results:We included 51 patients. Forty-six patients had bilateral TSS. The median average percent stenosis was 56%. Seventy-one percent of patients had stenoses .50%. Thirty-five of the 51 patients (69%) had no final visual field loss. Eight patients (16%) had a clinical course classified as poor. There was no difference in the average percent stenosis between those with good clinical courses vs those with poor courses (62% vs 56%, p 5 0.44). There was no difference in the percent stenosis based on the visual field grade (p 5 0.38). CSF opening pressure was not associated with either location or degree of TSS. Conclusion: TSS is common, if not universal, among patients with IIH, and is almost always bilateral.There is no correlation between the degree of TSS and the clinical course, including visual field loss, among patients with IIH, suggesting that clinical features, not the degree of TSS, should be used to determine management in IIH. Idiopathic intracranial hypertension (IIH) is a syndrome of isolated elevated intracranial pressure (ICP) of unknown etiology, responsible for visual loss from papilledema in about 25% of cases.

Background: 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.Methods: The index of TSS was used in the assessment of BTSS severity. Subjects underwent a standard lumbar puncture to measure the intracranial pressure (ICP). Papilledema and tinnitus were evaluated by using Frisén's grade and questionnaires for tinnitus handicap inventory (THI), respectively. The intensity and impact of headache was assessed by using 10-point Numeric Pain Rating Scale (NPRS) and six-item Headache Impact Test (HIT-6).Results: BTSS group had more patients with severe intracranial hypertension (IH) and less patients with normal ICP. BTSS patients had higher ICP than normal controls. Further analysis on VVC showed that VVC decreased the elevated ICP in BTSS patients and exerted no impact on ICP in normal controls. A similar incidence of VVC in BTSS patients and normal controls were found. BTSS patients with normal ICP and mild IH exhibited a higher incidence of VVC compared with those with severe IH. VVC, rather than the severity of BTSS, regulated the ICP. Furthermore, VVC alleviated IH-related clinical manifestations including papilledema and tinnitus in BTSS patients.Conclusions: The present study demonstrated BTSS is correlated with IH. The presence of VVC, which is postulated to be congenitally formed, normalizes the elevated ICP and alleviated IH-related symptoms in BTSS patients. VVC may be used as an indicator of relatively low ICP in BTSS patients.Trial registration: This study was registered retrospectively on 07/28/2020 (NCT04492332).
