- FIG 1.
A patient presented with a right-sided venous PT. The patient initially underwent stenting of the lateral sinus, which was unsuccessful because the tinnitus was not modified. A, An oblique 3D contrast-enhanced T1 sequence depicts a stenosis (white arrows) of the right MS before joining the jugular bulb (white arrowhead). B, A lateral angiogram confirms the stenosis (white arrow). C and D, Two 5 ×30 mm Carotid Wallstents were placed in the MS (dashed white line), lifting the stenosis and restoring a normal laminar flow (black arrow). The patient’s tinnitus was completely cured after the procedure. E and F, In the control venous CTA at 3 months, oblique and axial reconstructions, no thrombosis is depicted. Note that the stent is in the jugular bulb, close to the temporal bone and the jugular foramen.
- FIG 2.
The patient presented with a right-sided venous PT. A, An oblique 3D contrast-enhanced T1 sequence depicts a stenosis (white arrows) of the right MS (white arrow). Lateral angiogram (B) and oblique phlebography (C) confirm the extrinsic stenosis of the MS (white arrow); an intrinsic stenosis of the LS was also depicted (black arrowhead). Doppler measurement of the venous flow using a ComboWire confirmed the accelerated blood flow at the level of the MS stenosis. D, Oblique phlebography shows the deployment of the 5 ×30 mm Carotid Wallstent in the MS after placement of a first stent in the LS. E and F, Stents were placed in the MS and LS (white arrowheads), lifting the stenosis and restoring a normal laminar flow (black arrow). The patient’s tinnitus was completely cured after the procedure. Jug indicates jugular vein.
- FIG 3.
A patient presented with a right-sided venous PT associated with symptoms of IIH. A, An oblique 3D contrast-enhanced T1 sequence depicts a stenosis (white arrows) of the right MS; no MS was noted on the left side. B, Oblique phlebography confirms the extrinsic stenosis of the MS (white arrow); the LS was normal on the right side and absent (hypoplastic) on the left side. C, Two 5 × 30 mm Carotid Wallstents are deployed in the right occipital-marginal sinus (white arrowheads) (D), lifting the stenosis and restoring a normal MS caliber. Both the tinnitus and the symptoms of IIH disappeared. Jug indicates jugular vein.
