“…Interestingly, five of our patients developed a narrowing of the ipsilateral transverse sinus proximal to the stent (22%), similar to the phenomenon described in prior series 14 15. In each of these cases the vein of Labbe was observed draining the ipsilateral temporal lobe through the stent, with anterograde drainage through the ipsilateral sigmoid sinus.…”

Venous sinus stent placement has emerged as a promising treatment option for the subgroup of patients with IIH with a pressure gradient across a stenotic venous sinus. We observed long-term patency of all stents placed in this patient population. Further prospective investigation is necessary to improve our understanding of the phenomenon of sinus narrowing upstream of a patent stent and to establish definitively the long-term clinical efficacy of venous sinus stent placement for IIH.

“…Ahmed et al have recently published an update to this series which included an additional 18 cases 15. In total, seven of the 70 patients (10%) required a second stent placement secondary to clinical and hemodynamic deterioration associated with the development of a stenosis proximal to the stent.…”

“…The transverse and sigmoid sinuses are sites of endovascular stent placement, especially in the setting of IIH (Ahmed et al, ; Ahmed et al, ; Kumpe et al, ; Fields et al, ). IIH is a condition characterized by headaches due to raised intracranial pressure and subsequent papilledema resulting in vision loss.…”

“…Recent advancements in understanding the pathophysiology of idiopathic intracranial hypertension (IIH) have demonstrated that a subset of patients can have unilateral or bilateral stenoses at the junction of the transverse and sigmoid sinuses resulting in abnormal venous outflow. The treatment of this subset of patients with endovascular procedures, such as dural venous sinus stenting, is gaining popularity (Ahmed et al, ; Kumpe et al, ; Fields et al, ). However, there remains a paucity of knowledge about the anatomy of this venous junctional region, the likely etiology of stenosis at these points, and their clinical implications.…”

Venous sinus pathology can result in multiple pathological diseases, including idiopathic intracranial hypertension (IIH). There remains a paucity of information on anatomical luminal variations of the major venous sinuses which may contribute to the etiology of certain disease states. Thirty-six transverse and sigmoid sinuses were removed following dissection of 19 unfixed cadaveric heads. Sinuses were opened longitudinally to study luminal variations. A semiquantitative classification system was developed to assess septations and blind pouches. Seventy-nine percent of cadavers had a luminal anatomical variation. Forty-four percent and 42% of sinuses dissected had occurrence of a septations or blind pouches, respectively. Thirty percent of septations and 25% of pouches were classified as large. Incidence of anatomical variations was not statistically significant between cadaver gender or sinus laterality. Luminal variations are present in the transverse and sigmoid sinuses at rates higher than expected. This study is the first to report the presence of blind pouches in the luminal wall of transverse and sigmoid sinuses. These variations can have clinical importance to the endovascular surgeon and may also contribute to the pathophysiological etiology of venous sinus diseases. Anat
