BACKGROUND: Tandem occlusions of the internal carotid artery (ICA) and middle cerebral artery (MCA) occur in up to a third of patients with acute ischemic strokes undergoing endovascular mechanical thrombectomy. Understanding open neurosurgical management of associated complications with this procedure is important. CASE REPORT: A 67-year-old man with acute onset of left hemiparesis and a tandem right ICA and MCA occlusion. He underwent carotid stent angioplasty of a stenotic ICA, followed by attempted Solitaire stent retrieval of an MCA clot...

BACKGROUND: Predicting outcomes of acute stroke patients initially presenting with mild neurologic deficits is crucial in decision making regarding thrombolytic therapy. We examined the utility of individual National Institutes of Health Stroke Scale (NIHSS) score items or clusters of items as predictors of functional outcomes at 3 months after mild stroke. METHODS: Using a multicenter stroke registry database, we identified patients with acute ischemic stroke who presented within 4...

BACKGROUND: Carotid atherosclerosis is responsible for ~20% of ischemic strokes, but it is unclear whether carotid disease is associated with the presence of downstream silent brain infarction (SBI). We performed a systematic review and meta-analysis to study the relationship between SBI and 2 separate manifestations of carotid atherosclerosis, carotid intima-media thickening (IMT) and luminal stenosis. METHODS: Ovid MEDLINE, Ovid Embase, and the Cochrane Library Database were searched with an additional search of references and citing articles of target studies...

OBJECTIVE: Publications concerning the weather pattern of occurrence of the subarachnoid hemorrhage have produced controversial results. We chose to study subarachnoid hemorrhage occurring in oceanic climate with deep variations focusing on partial oxygen volume (pO2) and patient history. METHODS: Seventy-one patients had been successively recruited from a single center 45 km from the Atlantic shore. Climate conditions had been analyzed from 72 hours before subarachnoid hemorrhage to 24 hours after...

An 89-year-old woman with chronic atrial fibrillation, hypertension, chronic heart failure, and dementia was admitted to our hospital due to multiple small cerebral and cerebellar infarctions. Transthoracic echocardiogram revealed a floating calcified mass lesion arising from the endocardium of the posterior portion of the mitral annulus with mitral annular calcification. Furthermore, the mass had a heterogeneity of the echogenicity. The mass was diagnosed as a calcified amorphous tumor based on specific echocardiographic features...

The emerging use of mechanical thrombectomy for acute ischemic stroke treatment focuses on the importance of patient selection. Computed tomography perfusion (CTP) is one of widely used techniques. However, the accuracy and reliability of this modality is in debate among vascular neurologists. We present a case of an 80-year-old man admitted because of acute ischemic stroke. CT angiography demonstrated left proximal M2 occlusion. As CTP demonstrated signs of large ischemic core with no significant penumbra, mechanical thrombectomy was not performed following tPA administration...

BACKGROUND AND PURPOSE: Because magnetic resonance imaging (MRI) focuses on the morphological characteristics of carotid artery plaques, its diagnostic value with respect to plaque vulnerability is limited. We examined the correlation between N(ε)-(carboxymethyl)lysine (CML), a main chemical structure of advanced glycation end-products, and the vulnerability of plaques visualized on MRI scans. MATERIALS AND METHODS: We enrolled 43 patients who had undergone carotid artery stenting (CAS) for carotid artery stenosis; all underwent MRI studies, including black-blood MRI and diffusion-weighted imaging (DWI)...

INTRODUCTION: Cheyne-Stokes respiration (CSR) and central sleep apnea (CSA) are common in patients with heart failure and/or stroke. We aim to describe the cerebrovascular effects of CSR during the acute phase of stroke in a heart failure patient. CASE REPORT: A 74-year-old male with previous dilated cardiomyopathy had sudden onset of right hemiparesis and aphasia. A transcranial Doppler was performed with continuous measurement of blood pressure (BP) (Finometer) and end-tidal CO2 (nasal capnography)...

OBJECTIVE: For stroke patients, intensive nutritional management is an important and effective component of inpatient rehabilitation. Accordingly, acute care hospitals must detect and prevent malnutrition at an early stage. Blood transthyretin levels are widely used as a nutritional monitoring index in critically ill patients. Here, we had analyzed the relationship between the transthyretin levels during the acute phase and Functional Independence Measure in stroke patients undergoing convalescent rehabilitation...

BACKGROUND: Leukoaraiosis is associated with impaired cerebral perfusion, but the effect of individual and combined small-vessel disease (SVD) features on white matter perfusion is unclear. METHODS: We studied patients recruited with perfusion imaging in the Third International Stroke Trial. We rated individual SVD features (leukoaraiosis, lacunes) and brain atrophy on baseline plain computed tomography or magnetic resonance imaging. Separately, we assessed white matter at the level of the lateral ventricles in the cerebral hemisphere contralateral to the stroke for visible areas of hypoperfusion (present or absent) on 4 time-based perfusion imaging parameters...

A 29-year-old male patient with aphasia and mild weakness of the right arm arrived at the emergency room 4 hours after symptom onset. The computed tomography perfusion showed a typical delay in the time-based maps in the left occipital lobe and another hyperperfused area in the left frontal lobe. The follow-up magnetic resonance imaging confirmed cortical ischemic lesions in both areas. This case shows that besides hypoperfusion, hyperperfusion can also be found in the first stages of acute stroke, and it is highly suggestive of established ischemic lesions...

BACKGROUND: Chronic expanding intracerebral hematoma is a well-known complication of spontaneous intracerebral hemorrhage. However, because chronic expanding intracerebral hematoma is relatively rare, it has not been studied systemically. The purpose of this study was to characterize a patient population with chronic expanding intracerebral hematoma, and to identify the predictive factors for it. METHODS: We retrospectively evaluated 112 patients with spontaneous putaminal hemorrhage who were treated at our institution between January 1, 2010 and December 31, 2015...

BACKGROUND: Fabry disease (FD) is known as a rare cause of stroke. Recent studies suggested that FD is an underdiagnosed entity among young stroke patients. We aimed to investigate the frequency of FD in young cryptogenic stroke patients who lived in the City of Sakarya and to define the clinical features that help in recognizing patients with FD. METHODS: Acute ischemic stroke patients aged 18-55 years who were admitted to our hospital between October 2013 and September 2016 were evaluated for inclusion...

OBJECTIVE: Although neutrophil-to-lymphocyte ratio (NLR) has been reported to correlate with subclinical atherosclerosis, little is known about the relationship between NLR and carotid stenosis. METHODS: Only patients with extracranial carotid stenosis in digital subtraction angiography (N = 105) were enrolled in this study. Maximal and accumulated extracranial carotid artery stenosis was measured. Stepwise multiple linear regression was performed to identify independent factors associated with maximal and accumulated extracranial carotid artery stenosis...

BACKGROUND: Individuals who present to the emergency departments of safety-net systems often have poorly controlled risk factors due to lack of primary care. Little is known about potential differences in presenting characteristics, discharge medications, and discharge destinations of patients with acute ischemic stroke (AIS) who present to safety-net settings versus university medical centers (UMCs). METHODS: Demographic characteristics, medical history, premorbid medication use, stroke severity, discharge medications, and discharge destination were assessed among consecutive admissions for AIS over a 2-year period at a UMC (n = 385) versus 2 university-affiliated safety-net hospitals (SNHs) (n = 346) in Los Angeles County...
