A: Severe transverse sinus stenosis was observed on the left side on pre-operative computed tomography, which may be formed by arachnoid granulations; B-C: The transverse sinus stenosis was well expanded by the stent; D: A slight filling defect in the stent was observed on the image obtained 1 year after surgery; E: The filling defect was enlarged after another year.
