Small-vessel Disease Burden and Early Risk of Stroke After Transient Ischemic Attack
Small-vessel Disease Burden and Early Risk of Stroke After Transient Ischemic Attack
Predicting the risk of stroke remains a challenge in the management of transient ischemic
 attack (TIA). In addition to clinical variables, morphological features such as the presence
 of a diffusion weighted sequence (DWI) lesion and carotid stenosis of at least 50% improve
 risk stratification and are considered in the literature. score ABCD3-I1. Several studies
 have shown that brain microhemorrhages are associated with the risk of early stroke in
 patients with TIA. Data on white matter hypersignals on the T2-weighted sequence or FLAIR
 (FLuid Attenuated Inversion Recovery) are more conflicting. The global microangiopathic load,
 including the gaps, the hypersignals of the white matter, the perivascular spaces visible on
 MRI in the basal ganglia, especially when they are very numerous (> 20) and the gaps, have
 recently been described as being associated with stroke risk within 2 to 3 years of TIA or
 ischemic stroke. To date, the predictive value of global microangiopathic burden on early
 stroke risk in the course of TIA is not known.
