“…The maximum mean diameter of the SSS (7.3±0.8 mm) dominant transverse (7.5±1.2 mm) and sigmoid sinus (8.8±1.8 mm) of our study population are similar to the maximum endoluminal width measured on the morphometric analysis of the cerebral venous sinuses (7.9±1.5 mm, 8.5±2.4 mm and 8.6±2.0mm respectively). [ 18 ] We realize this is a single center experience and recommended larger multicenter trials to support our findings.…”

PurposeMagnetic resonance venography (MRV) has not been validated in pre-operative planning of the dural venous sinus stenting (VSS) among idiopathic intracranial hypertension (IIH) patients. We aim to prospectively evaluate dural venous sinus measurement in IIH patient population on two-dimensional time-of-flight (2D-TOF) MRV and Three-dimensional contrast-enhanced (3D-CE) MRV acquisitions and compare them against real-time endoluminal measurements with intravascular ultrasound (IVUS), served as the reference.Materials and methodsThe study has been approved by the Weill Cornell Medicine institutional review board. All patients signed written informed consent approved by IRB. Prospective evaluation of forty-five consecutive IIH patients treated with VSS at our institution were evaluated. Patients with pre-stent magnetic resonance venography (MRV) ≤ 6-months of VSS and intravascular ultrasound (IVUS) during VSS constituted the study population. Maximum diameter (in mm), Area (in cm2) and Perimeter (in cm) were measured at posterior 1/3rd of superior sagittal sinus (SSS), proximal transverse sinus (PTS), proximal sigmoid sinus (PSS) and mid sigmoid sinus (MSS) on 2D-TOF-MRV, 3D-CE-MRV and IVUS. Statistical analysis performed using box and whisker plots, Bland-Altman analysis and paired sample t-test.ResultsTwenty (n = 20) patients constituted our study population. The mean age was 30±11 years (7–59 years) and 18 out of 20 were female patients. Mean weight and BMI (range) were 86.3±18.3 kilograms (30.8–107.5 kgs) and 32.9±6.8 kg/M2 (16.4–48.3kg/M2) respectively. The CE-MRV significantly oversized the cerebral venous sinuses compared to TOF-MRV (Dmax: +2.0±1.35 mm, p<0.001; Area: +13.31±10.92 mm2, p<0.001 and Perimeter: +4.79±3.4 mm, p<0.001) and IVUS (Dmax: +1.52±2.16 mm, p<0.001; Area: +10.03±21.5 mm2, p<0.001 and Perimeter: +4.15±3.27 mm, p<0.001). The TOF-MRV sinus measurements were in good agreement with the IVUS measurements with no significant variation (Dmax: +.21±2.23 mm, p = 0.49; Area: +2.51±20.41mm2, p = 0.347 and Perimeter: +.001±1.11 mm, p = 0.991).ConclusionWe report baseline cerebral venous sinus measurements (maximum diameter, area and perimeter) in patients with idiopathic intracranial hypertension. In our experience, TOF-MRV is a reliable representation of endoluminal cerebral venous sinus dimensions, and CE-MRV measurements reflected an overestimation of the endoluminal sinus dimensions when compared against the real time IVUS measurements.

“…Similar fi nding was supported by the study done by Thamke et al, Patel R et al and Shruti et al in their study. 10,11,13 Embryological, the difference in size of the two internal jugular veins, when present, is already visible in the human embryo at the 23mm stage (8 weeks post-conception) and probably results from differences in the pattern of development of the right and left brachiocephalic veins. 6 In a study done by Shruti et al 11 right jugular foramen was greater than left in 178 (71.2%), lesser than left in 52 (20.8%) while equal to left 20 (8%) patients.…”

Cranial venous sinus anatomy is fundamental in neurosurgery and radiology, especially in surgical planning and treatment of neurological diseases. In this study, we aimed to study the morphometric relationship of the transverse sinus with sigmoid sinus groove and jugular foramen and imply if this relationship could aid in diagnosing the transverse sinus thrombosis. This is a retrospective analytical study conducted in our center among 30 patients who underwent Computed Tomography (CT) venogram during a period of 1 year. Diameter of transverse sinus and sigmoid groove at midpoint, and diameter of jugular foramen as it enters the skull base were collected. Relation of transverse sinus with sigmoid sinus groove and jugular foramen was analyzed. There were 60 transverse sinuses in the study with left and right being 50% (30 each). Mean age of patients collected was 53.20 years. There were 43.3% male and 56.7% female patients. Diameter of the Transverse sinus has statistically significantly linear relationship with the diameter of the sigmoid sinus groove and jugular foramen (p<0.001) and was positively correlated (r= 0.651 and 0.624 respectively). Diameter of the transverse sinus has significant positive linear correlation with the sigmoid sinus groove and jugular foramen.

Introduction Sigmoid sinus (SS) variations have been classified variously in the literature. These classifications suffer from some form of shortcoming from a clinical point of view for their application. Objective We propose a clinically relevant classification of the SS in relation to the posterior semicircular canal (PSCC) and to the exposure of the presigmoid dural plate. The positioning of the SS was analyzed with reference to the volume of the mastoid and to the level of mastoid pneumatization. Methods A total of 94 formalin-preserved human cadaveric temporal bones were microdissected to carry out a complete mastoidectomy. The SS, the presigmoid dural plate, and the PSCC were exposed, and the position of the former was analyzed in relation to the latter two in order to classify the position of the SS into three grades. Results Grade I had the best exposure of the presigmoid dura and of the PSCC, while grade III had the poorest exposure of the presigmoid dura and of the PSCC. Grade I SS was associated with good pneumatization and higher mastoid volumes compared with grades II and III. Conclusions The SS exhibits considerable anatomic variability. A favorable positioning of the SS is associated with a large mastoid volume and pneumatization. A careful preoperative study of the imaging may help in understanding the positioning of the SS and the safety of various transmastoid approaches.
