Abstract:
Objective To investigate the MRI manifestations and analyze the prognostic factors of patients with anterior circulation minor stroke and nonGminor stroke in Qinghai plateau.Methods 41 6 cases of the first admission,including 1 9 2 patients with minor stroke and 224 patients with nonGminor stroke.MRI and MRA examinations of the head were completed in all patients within 72 h of admission.Patients were followed up for one year to observe the recurrence of stroke,and the quality of life was evaluated with the help of modified Rankin Scale (MRS)scores.Results (1)MRA showed that 36.98% of the minor stroke and 58.93% of the nonGminor stroke had the stenosis of the responsible artery at the infarction site.The difference was significant (χ2＝ 1 9.94,P＜ 0.00 1 ).(2 )MRI showed that the initial infarction sites of minor stroke and nonGminor stroke were different (χ2＝4.47 ,P＜0.005 ).(3 )The recurrence rate was 10.42% in minor stroke and 12.05% in nonGminor stroke.There was no significance between the two groups (χ2＝ 0.28,P＞0.05).(4) Among patients with poor prognostic outcomes (whose MRS≥3),there were 1 9 cases of minor stroke and 6 1 cases of nonGminor stroke,and the difference was significant (χ2＝20.00,P＜0.0 1 ).Conclusion LesionGrelated vascular stenosis in patients with minor stroke is mild and the primary infarction is more common in isolated subcortical or deep white matter.The stenosis is severe in patients with nonGminor stroke,and the infarct lesion is often subcortical with or without cortical or deep white matter.There is no difference in recurrence risk between minor stroke and nonGminor stroke.The prognosis of minor stroke is better than that of nonGminor stroke.
