Long-term patency of venous sinus stents for idiopathic intracranial hypertension

Abstract

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.

New frontiers in venous sinus stenting: Illustrative cases

“…However, recent reports have detailed the successful treatment of patients with IIH by venous sinus stenting, which alleviated both headaches and visual symptoms [1][2][3][4]. Given these promising results, our report adds to the literature by illustrating the successful treatment of two variant forms of IIH with venous sinus stenting.…”

Dural sinus stenting for idiopathic intracranial hypertension: factors associated with hemodynamic failure and management with extended stenting

“…Development of a new stenosis after stent placement has been recognized by multiple investigators 3 5 6 12 16. Although in-stent stenosis occurs rarely,5 the majority of stenoses occur owing to collapse of the transverse sinus above the upper end of the stent 4–6 12.…”

“…Although in-stent stenosis occurs rarely,5 the majority of stenoses occur owing to collapse of the transverse sinus above the upper end of the stent 4–6 12. A review of 17 series by Starke et al 3 summarized 185 patients.…”

“…Development of a new stent-adjacent stenosis in the transverse sinus above the stent has been noted in 11.5%,4 21.7%,5 and 35.7%6 of patients undergoing stent placement for IIH. Concurrent narrowing of the posterior superior sagittal sinus (SSS) has been reported in one patient 6.…”

“…At our institution, a venous pressure gradient of at least 10 mmHg across the stenotic segment is necessary to be considered for VSS. In contrast to stents deployed in intracranial arteries, in-stent stenosis or occlusion rarely occurs after stenting of major dural venous sinuses, although stent-adjacent stenosis tends to develop after VSS [4][5][6]. Additionally, VSS may be more cost-effective than CSF diversion, due to a significantly lower reoperation rate [7].…”
