BACKGROUND AND PURPOSE The purpose of this study was to evaluate whether bright vessel appearance on arterial spin labeling (ASL) MRI can help localize arterial occlusion sites in patients with acute ischemic stroke. METHODS Patients who underwent MRI for suspected acute ischemic stroke, as identified by an area of restricted diffusion, were included. All images were visually analyzed for the...

background :in addition to diagnosing the acute myocardial infarction (mi), stratifying high-risk patients and proper treatment strategies are important issues in managing patients complaining of chest pain and suspecting mi. many studies have been conducted to predict the occlusion site by interpreting the st segment deviations in electrocardiogram (ecg).additional posterior and right precordi...

background: small side branches, albeit less important than their larger counterparts, have not yet received due attention in the literature. nor has there ever been a comparison between drug-eluting stents and bare metal stents apropos side branch occlusion . the aim of this study was to compare the patency of small (≥0.5 and ≤1.5 mm in diameter) side branches with respect to bare metal vs. dr...

Letters to the Editor will be published, if suitable, as space permits. They should not exceed 1,000 words (typed double-spaced) in length and may be subject to editing or abridgment. To the Editor: The four-vessel occlusion method developed by Drs. Pulsi-nelli and Brierley is widely used as an experimental model for bilateral hemispheric ischemia in the field of pathophysiology. 1-2 However, t...

BACKGROUND AND PURPOSE In the rat four-vessel occlusion model with 30 minutes of ischemia most agents have failed to be of benefit when given after ischemia. Because postischemia administration is more clinically relevant, we evaluated the antioxidant LY231617 (2,6-bis(1,1-dimethylethyl)-4-[[(1-ethyl)amino]methyl]phenol hydrochloride]) when administered after 30 minutes of four-vessel occlusion...

conclusion coil embolization showed successful outcomes in the treatment of intracranial aneurysms with a low complication rate. results immediately after the procedure, the total occlusion was seen in 76 (86.4%), subtotal occlusion in six (6.8%), and partial occlusion in six patients (6.8%). there was no significant relationship between the aneurysm size, aneurysm neck size, and location of th...
