Background: Transient ischemic attack (TIA) is an independent risk factor of recurrent stroke. Early assessment of intracranial and extracranial vessels is critical to assessing risk. TIA Patients with intracranial or extracranial arterial stenosis are at high risk of recurrent stroke.
Aim and objectives: This study is conducted to assess the value of transcranial (TCD) Doppler ultrasonography to predict the occurrence of cerebrovascular events after transient ischemic attack.
Patients and Methods: This study was a prospective cohort study that was conducted on 75 patients presented with TIA fulfilling its criteria who admitted at neuropsychiatry department in Benha University Hospital. Transcranial and extracranial Doppler were done for each patient, at neurovascular ultrasonographic laboratories, by Phillips clear vue 650 ultrasound.
RESULTS: During follow up of the patients, 17(22%) out of studied sample experienced an ischemic stroke or TIA. By using TCD stenosis was significantly higher in those with cerebrovascular events (58.8%) compared to those without (8.6%), P value was |
