Carotid plaque characteristics on magnetic resonance plaque imaging following long-term cilostazol therapy.
Cilostazol is an antiplatelet agent that can induce the regression of atherosclerosis. However, its long-term effects on plaque involution of the cervical carotid arteries remain unknown. Thus, we aimed to evaluate the effect of long-term cilostazol administration on carotid plaques using quantitative magnetic resonance (MR) plaque imaging. ⋯ Signal alterations on MR plaque imaging indicated the increase of fibrous components and the decrease of lipid/necrotic components in the carotid plaque during the cilostazol therapy.

Association of the ASCO classification with the executive function subscores of the Montreal cognitive assessment in patients with postischemic stroke.
The ASCO classification can evaluate the etiology and mechanisms of ischemic stroke more comprehensively and systematically than conventional stroke classification systems such as Trial of Org 10172 in Acute Stroke Treatment (TOAST). Simultaneously, risk factors for cognitive impairment such as arterial sclerosis, leukoaraiosis, and atrial fibrillation can also be gathered and graded using the ASCO classification. ⋯ These results suggest that the ASCO phenotypic classification of stroke is useful not only for assessing the etiology of ischemic stroke but also for predicting cognitive decline after ischemic stroke.

Review Case Reports Meta AnalysisIntracerebral hemorrhage associated with oral phenylephrine use: a case report and review of the literature.
Prior reports have linked both ischemic and hemorrhagic stroke to use of sympathomimetic drugs including phenylephrine. The purpose of this study is to describe the first case, to our knowledge of intracerebral hemorrhage (ICH) after oral use of phenylephrine and to systematically review the literature on phenylephrine and acute stroke. ⋯ It is scientifically plausible that phenylephrine may cause strokes, consistent with the pharmacologic properties and adverse event profiles of similar amphetamine-like sympathomimetics. As RCVS has been well described in association with over-the-counter sympathomimetics, a likely, although not definitive, causal relationship between phenylephrine and ICH is proposed.

Relationship between diffusion tensor fractional anisotropy and long-term motor outcome in patients with hemiparesis after middle cerebral artery infarction.
Magnetic resonance diffusion tensor fractional anisotropy (DTI-FA) is often used to characterize neural damage after stroke. Here we assessed the relationship between DTI-FA and long-term motor outcome in patients after middle cerebral artery (MCA) infarction. ⋯ The results suggest that DTI-FA is applicable for predicting the long-term outcome of extremity functions after MCA infarction.

Case Reports"Contrast-less" stent-assisted coiling of an A1 aneurysm.
Iodine-based contrast medium used in diagnostic and therapeutic cerebrovascular imaging may cause renal toxicity, especially in patients with underlying renal impairment. Contrast dilution may impede efforts of the neurointerventionalist to treat intracranial vascular pathology. ⋯ Further development of and experience with this technique is needed to improve its safety and efficacy.
