“…Strydom et al [ 27 ] studied the transverse sinuses of both cadavers and patients and found that 29.4% of the 102 subjects had septations in them. Altafulla et al [ 28 ] also found a total of 42 septations in 24 cadaveric transverse sinuses studied (12 cadavers). In the present study, all basilar venous plexuses were found to contain such trabeculae.…”

“…Stenosis of the transverse sinus is also well known to contribute idiopathic intracranial hypertension [ 27 , 29 ]. The possible benefits of dural sinus septations were discussed by Altafulla et al [ 28 ] in their study of the architecture of transverse sinus trabeculations and their tensile strength. The authors suggested that these intraluminal septations help maintain the three-dimensional shape of the dural sinuses where hemodynamic stress was maximal, for instance where the direction of blood flow changes and in areas of maximum curvature of the sinuses.…”

Few studies have examined the basilar venous plexus (BVP) and to our knowledge, no previous study has described its histology. The present anatomical study was performed to better elucidate these structures. In ten cadavers, the BVP was dissected. The anatomical and histological evaluation of the intraluminal trabeculae within this sinus were evaluated. Once all gross measurements were made, the clivus and overlying BVP were harvested and submitted for histological analysis. A BVP was identified in all specimens and in each of these, intraluminal trabeculae were identified. The mean number of trabeculae per plexus was five. These were most concentrated in the upper half of the clivus and were more often centrally located. These septations traveled in a posterior to anterior direction and usually, from inferiorly to superiorly however some were noted to travel horizontally. In a few specimens the trabeculae had wider bases, especially on the posterior attachment to the meningeal layer of dura mater. More commonly, the trabeculae ended in a denticulate form at their two terminal ends. The trabeculae were on average were 0.85 mm in length. The mean width of the trabeculae was 0.35 mm. These septations were consistent with the cords of Willis as are found in the lumen of some of the other intradural venous sinuses. An understanding of the internal anatomy of the BVP can aid in our understanding of venous pathology. Furthermore, this knowledge will benefit patients undergoing interventional treatments that involve the BVP.

“…From an anatomical perspective, the TS is vulnerable to collapse toward the lateral side due to lack of supportive structures, such as the septum and trabecula. 18) In patients with IIH, sinus stenosis occurs in the lateral side of the TS; thus, SAS may occur in the remaining parts of TS after stenting for the same reason.…”

We report the case of a patient with recurred idiopathic intracranial hypertension (IIH) with transverse sinus (TS) stenosis after initial stenting, which was treated with additional stent placed in tandem to the secondarily occurred stent-adjacent stenosis (SAS).Case Presentation: A 41-year-old woman complained of reduced visual acuity and blurred vision, and presented with papilledema. Lumbar puncture revealed an opening pressure of 36 cmH 2 O. MRI revealed no space-occupying lesions, and the patient was diagnosed with IIH based on the modified Dandy criteria. MR venography revealed stenosis in the right and hypoplastic left TS. The patient complained of headache and neck pain after each lumbar puncture for examination. Venous sinus stenting (VSS) was performed in the right TS. One month after stenting, follow-up angiography revealed stenosis in the remaining parts of TS. Five months after stenting, IIH recurred, and SAS was detected on angiography. An additional stenting procedure was performed. Three months after the second treatment, her symptoms disappeared and cerebrospinal fluid pressure was normalized. Conclusion:Patients with post-VSS recurrent IIH may develop restenosis in the remaining parts of TS at variable progression speeds. In this case, angiography revealed gradually advancing stenosis that seemed to form SAS at the time of recurrence. If the initial VSS is effective for IIH, SAS can also be treated effectively and less invasively with a second stent placement covering the entire TS length.

“…However, in another study, the mean diameter of the transverse sinus was 6.21 mm and 6.30 mm on right and left sides, respectively thus confirming it's variability. 22 The torcula which is the confluence of sinuses is believed to be located below or on the external occipital protuberance. However recent studies have shown that the torcula lies slightly superior or on the right side of the external occipital protuberance.…”

The superior sagittal sinus and its draining veins are important venous structures that pose a formidable obstacle to surgical management. It is crucial and essential for the surgeon to acquire the knowledge of the normal course and variations of the sinus and its draining veins. This helps in pre-operative planning and execution of pre-operative measures or manoeuvres needed to minimize blood loss or intra-operative injuries to the sinus.This study was conducted to delineate the microsurgical anatomy of the superior sagittal sinus to look for any variations among Sabah people as compared to the general studies available. This study was based on dissection of fresh cadavers. Thirty fresh cadavers were examined in Forensic Department, Hospital Queen Elizabeth, Sabah between August 2020 to June 2021. They were anatomically analysed and studied through a data collection sheet. All data were analysed using Statistical Package for the Social Science (SPSS). The study revealed that male was predominantly significant and forty-three percent were of Bajau race. Fifty percent of cadavers were around the 50-60 years old age group. The position of superior sagittal sinus (SSS) was variable and within 1cm distance from the midline. The origin of SSS varied from at the foramen caecum to posterior from the foramen caecum. The total length of SSS averages around 321-351mm. The number of draining veins on the right and left side of SSS were divided into anterior, middle and posterior components with an average of three to six veins respectively on each side. The number of venous lacunae on the right and left side of SSS were divided as well into anterior, middle and posterior components with an average of one to two venous lacunae on each side respectively. The central sulcus was located 48.87mm posterior to coronal suture and 131.1mm anterior to the lambdoid suture. The Trolard vein was located 53.56mm posterior to coronal suture and 127.36mm anterior to the lambdoid suture. The Trolard vein was situated in average 3.68mm posterior to central sulcus and predominantly drains into the venous lacuna. Ninety percent of SSS terminate on the right of the transverse sinus. The position of torcula varies from the location on the external occipital protuberance to slightly on the right side of the external occipital protuberance. This study shows that anatomical landmarks among the local population did not differ significantly from that reported by other studies throughout the world. Therefore, the basic neurosurgical principles and craniometric points outlined universally is applicable to this population without the need for any modifications.
