Transient Global Amnesia and High-Grade Styloidogenic Jugular Vein Stenosis
In this case-control study of patients with TGA vs healthy participants, TGA was associated with high-grade SJVC in the presence of small-caliber IJVs, with an approximately 70% right-sided or bilateral IJV stenosis threshold emerging as a promising imaging covariate for supporting the clinical diagnosis of TGA. These results suggest that MRI assessment of SJVC severity may improve diagnostic accuracy in atypical TGA presentations.
