Abstract: Objective To evaluate the relationship between ABCD2 score and cerebrovacular stenosis of patients with transient ischemic attack(TIA).Methods We retrospectively reviewed the medical records of 88 patients with TIA; all of them were examined with the magnetic resonance angiography(MRA). All patients were divided into two groups according to cerebrovascular vascular stenosis ≥50% or not, and divided into two groups according to ABCD2 score ≥4 point or not. The relationship between ABCD2 score andcerebrovaculare vascular stenosis was analyzed.Results Group stenosis ≥50% were more likely to have ABCD2 score ≥4 compared with group stenosis <50%(74.4% vs 44.9%, OR =3.559, 95%CI 1.428-8.868, P =0.005). Group stenosis ≥50% were more likely to have stroke history than those stenosis <50%(33.3% vs 10.2%, OR =4.400,95%CI 1.408~4.869, P =0.01). The stroke within 2 days after TIA is higher in group cerebrovascular stenosis ≥50% than that in group stenosis <50%(10.3% vs 0%, OR =0.417, 95%CI 0.324-0.537,P =0.04).Conclusion The patients with ABCD2 score≥4 show higher rate of cerebrovascular stenosis. Patients with previous stroke more likely to undergo cerebrovascular vascular stenosis. The stroke within 2 days after TIA is higher in patients with cerebrovascualr stenosis ≥50%.
