Pakartotinės smegenų išemijos rizika ir ją nuspėjantys veiksniai iki operacinio simptominės vidinės miego arterijos gydymo.

Extracranial internal carotid artery (ICA) stenosis accounts for 10-20% of all strokes. Patients with recently symptomatic ICA stenosis have a high risk of early recurrent ischemic stroke. Endarterectomy is the main choice of treatment of these patients; however, some of them suffer repeated cerebral ischemic events before surgery. It is therefore important to identify high-risk patients, so that these can be treated in more timely fashion. Seventy one patients with first ever ipsilateral cerebral event (38 after TIA and 33 after stroke) were prospectively followed until carotid endarterectomy. Thirty six patients (50.7 %) had suffered repeated ischemic events (6 new TIA and 30 cerebral infarctions). The patients with repeated ischemia more frequently had peripheral arterial disease (p-0.045), high-grade stenosis (p-0.021) and low echogenicity of arterial plaque (p-0.017), the first event reported more frequently with arm paresis (p-0.012), these patients had a higher ABCD2 prognostic scale scores (p-0.001). Multivariable regression analysis revealed that higher estimates of the ABCD2 scores, low echogenicity of arterial plaque, increased common carotid IM thickness, and presence of collateral blood flow through anterior commtmicating artery were independent predictors of further cerebral ischemic events.
