Objective: To report the clinical, radiological, and haemodynamic data of three patients with AIS who underwent IAT.

Material and Methods: Two men and one woman, mean age of 61.6, two with MCA occlusion and one with posterior AIS, were treated. Clinical outcome was assessed according to NIHSS and mRS on day 1, 30 and 90. Neuroimaging included non-contrast CT or MRI, diffusion and angio MRI. All patients underwent cerebral angiography and met criteria for endovascular TL. Transcranial duplex scanning was used for haemodynamic assessment of the occlusion and recanalization. Actiyse was infused supraselectively via microcatheter in a mean dose of 38.3 mg. TICI score was documented at the end of the procedure. Post-procedural I.V. 24 h heparin infusion was given to one patient with poor TICI result.

Objective: Carotid arterial stenosis becomes more common and important risk factor for stroke patients in Asian area. We reviewed stroke database to investigate changes of carotid duplex sonographic findings which reflects hemodynamic changes before and after carotid stenting.

Material and Methods: Stroke patients of which carotid stenting have been done when admitted at the National Health Insurance Service Ilsan Hospital from January 2007 to December 2012 with available carotid ultrasound study that was done before and after carotid stenting formed the analysis cohorts. Retrospective review was performed.

Objective: Bow Hunter´s syndrome (BHS) reflects a perturbation of blood flow provoked by changes in the position of head. Symptoms include syncope, dizziness, vertigo, visual blurriness, drop attacks, tinnitus, hypoacusis, and sensory or motor deficits. Here we describe the application of Transcranial Doppler (TCD) in diagnosis of BHS.

Objective: Previous studies concluded that symptomatic carotid plaques are echolucent on ultrasound, whereas asymptomatic ones are echogenic. The aim of this study was to determine whether juxtaluminal plaque echogenicity (juxtaluminal 25% plaque area) constitutes a better discriminator of the symptomatic and asymptomatic status, as compared to global plaque echogenicity, in various degrees of stenosis.

Material and Methods: Analysis involved imaging by duplex of 100 carotid plaques of more than 50% stenosis (86 patients, 50 symptomatic and 50 asymptomatic plaques), capturing, digitisation and normalisation in a computer in a standard way. The global plaque Grey Scale Median (GSMglobal) was evaluated to distinguish dark (low GSM) from bright (high GSM) plaques. Subsequently, juxtaluminal 25% plaque area GSM (GSMjl25%) was evaluated semi-quantitatively in the same computer software. Stenosis was evaluated on duplex.

Approximately 13 million deaths per year are caused by vascular diseases, ischemic heart disease and stroke account for 22.3% of the total yearly deaths in the world, 12.2% and 9.7% are due to ischemic heart disease and stroke respectively. Myocardial infarction is the leading cause of long-term mortality in stroke surviving patients, although stroke is the leading cause of disability in the world. Atherosclerotic carotid artery disease is the cause of ischemic ischemic stroke in about 20% of cases.
