Abstract
Background: Transient ischemic attack (TIA) is an independent risk factor of recurrent stroke. TIA Patients with intracranial or extracranial arterial stenosis are at high risk of recurrent stroke. Early assessment of intracranial and extracranial vessels is important to assess risk. Aim of the work: This study was conducted to assess the value of transcranial (TCD) Doppler ultrasonography to predict the occurrence of cerebrovascular events after TIA. Patient and Methods: This study was carried out in neuropsychiatry department in Benha University Hospital , it was conducted on 75 patients presented with TIA, transcranial and extracranial Doppler were done for each patient .Results : During follow up of the patients, 17(22%) out of studied sample experienced an ischemic stroke or TIA, TCD showed intracranial stenosis in 15(20%) patients, ECD (Extracranial Doppler )showed plaques of extracranial arteries in 18(24%) patients and stenosis of theses arteries in 9(12%) patients. Multivariate logistic regression analysis revealed stenosis detected by TCD and ECD was a predictor for cerebrovascular event (TCD: Odds ratio= 8.977 & 95% Confidence interval ranged from 1.889 – 42.652, P value was 0.006 ; ECD: Odds ratio = 26.169 & 95% Confidence interval ranged from 3.875 – 176.722, P value was 0.001). Conclusion: TIA patients with abnormal TCD finding are high risk to develop further cerebral ischemic events. And, TCD is important diagnostic and prognostic procedure in patients with TIA.
