BACKGROUND AND PURPOSE The present study investigated the prevalence of cerebral microemboli detected by transcranial Doppler sonography in unselected stroke and transient ischemic attack (TIA) patients under standard clinical conditions. We aimed to evaluate the feasibility and the value of the method for clinical use. METHODS The records of 937 consecutive patients who were investigated bet...
Background: Clinical information about stroke in the vertebrobasilar territory has lagged behind that for anterior circulation syndrome. This is the first report from posterior circulation syndrome registry in Iran. Methods: Consecutive patients with brain infarction in vertebrobasilar territory admitted to Ghaem hospital, Mashhad were enrolled in a prospective study during 2006-2007. Diagnosis...
Introduction Cryptogenic stroke is present in about 40% of ischemic stroke patients. Extracardiac shunt related to pulmonary arteriovenous fistula (PAVF) could be a rare potential risk factor for embolic stroke. Most PAVFs are multiple, congenital, and associated with hereditary conditions. On the other hand, isolated PAVFs are rare conditions and an uncommon cause of cryptogenic stoke. Case ...
Introduction: Some recent studies have shown that citicoline improves clinical symptoms in patients with stroke. Citicoline's mechanism of action in improving the clinical symptoms is not recognized yet. The aim of this study was to evaluate the cerebrovascular hemodynamic status in patients with ischemic stroke treated with citicoline compared with the control group. <st...
Acute ischemic stroke due to embolic occlusion of the middle cerebral artery (MCA) in patients with chronic ipsilateral internal carotid artery (ICA) occlusion is quite rare. Several previous reports demonstrated that intra-arterial (IA) thrombolytic therapy or aspiration thrombectomy using the cross-circulation technique via an alternative collateral pathway is feasible in acute stroke patient...
Cardioembolic infarction accounts for one quarter of all cerebral infarcts and is the most severe subtype of ischemic stroke. The rate of in-hospital death may be as high as 27% and a few patients are symptom-free at discharge from the hospital. Major cardiac sources of embolism are well-established and cardioembolic stroke is largely preventable. However, once stroke due to cardiac embolism ha...
Myxomas, the most common primary cardiac tumors, are known as a source of cardiogenic emboli. The possibility of their early detection has made them of great importance for emergency medicines. Detection of the disease is probable at early stages using echocardiography and associate complications such as syncope, cerebral embolic ischemic strokes, and sudden death. We report experience of a rar...
BACKGROUND Hemodynamic insufficiency is often considered the cause of ischemic stroke in patients with moyamoya syndrome. While high-intensity transient signals (HITS) on transcranial Doppler (TCD) have been reported in this population, the relationship between these signals and ischemic symptoms is not clearly established. Accordingly, current treatment is directed at improving perfusion. CL...
BACKGROUND Middle cerebral artery (MCA) stenosis is a rare occlusive disease in western populations, with a high risk of stroke recurrence. An artery-to-artery embolic mechanism has been argued. We report the detection of a new pattern of microembolic signals (MES) in the MCA poststenotic segment in a patient with multiple recurrent transient ischemic attacks. CASE DESCRIPTION A 75-year-old m...
BACKGROUND The optimal timing to administer non-vitamin K oral anticoagulants (NOACs) in patients with acute ischemic stroke and atrial fibrillation is unclear. This prospective observational multicenter study evaluated the rates of early recurrence and major bleeding (within 90 days) and their timing in patients with acute ischemic stroke and atrial fibrillation who received NOACs for secondar...
