The Detrimental Effect of Aging on Leptomeningeal Collaterals in Ischemic Stroke
Conclusion: Our findings show that there is a significant interplay between patient age and adequacy of leptomeningeal collateral circulation in patients with proximal MCA occlusion. The relationship could contribute to adverse tissue outcome and thereby to unfavorable clinical outcome observed in elderly patients with ischemic stroke.

Internal Cerebral Vein Asymmetry on Follow-up Brain Computed Tomography after Intravenous Thrombolysis in Acute Anterior Circulation Ischemic Stroke Is Associated with Poor Outcome
Background: Identifying early predictors of functional outcome after acute ischemic stroke (AIS) is important for planning rehabilitation strategies. Internal cerebral veins (ICV) drain deep parts of brain, run parallel to each other, and consistently seen on computed tomography angiography (CTA). Even minor asymmetry in their filling can be identified. We hypothesized that venous drainage would be impaired in patients with acute occlusion of internal carotid artery or middle cerebral artery. Because systemic thrombolysis can alter the vascular findings, we evaluated the relationship between ICV asymmetry on follow-up CTA ...

Early and Continuous Neurologic Improvements after Intravenous Thrombolysis Are Strong Predictors of Favorable Long-term Outcomes in Acute Ischemic Stroke
Background: Intravenously administered tissue plasminogen activator (IV tPA) remains the only approved therapeutic agent for arterial recanalization in acute ischemic stroke (AIS). Considerable proportion of AIS patients demonstrate changes in their neurologic status within the first 24 hours of intravenous thrombolysis with IV tPA. However, there are little available data on the course of clinical recovery in subacute 2- to 24-hour window and its impact. We evaluated whether neurologic improvement at 2 and 24 hours after IV tPA bolus can predict functional outcomes in AIS patients at 3 months.Methods: Data for consecutive...

CHADS2- and CHA2DS2VASc Scores and Embolic Risk in Left Ventricular Hypertrabeculation/Noncompaction
Background: Left ventricular hypertrabeculation/noncompaction (LVHT) is associated with stroke or embolism (S/E). The aim of this study was to assess if the Congestive heart failure, Hypertension, Age>75 years, Diabetes, and Stroke (CHADS2) and CHA2DS2VASc scores are different between LVHT-patients with and without stroke/embolism.Methods: Records of LVHT patients were retrospectively screened. For stroke classification, the Trial of Org 10172 in Acute Stroke Treatment (TOAST) criteria were applied, for peripheral embolism angiographic findings. Baseline data were compared between patients with and without S/E.Results: In ...

Intracranial Arterial Stenosis
Intracranial arterial stenosis (IAS) is usually attributable to atherosclerosis and corresponds to the most common cause of stroke worldwide. It is very prevalent among African, Asian, and Hispanic populations. Advancing age, systolic hypertension, diabetes mellitus, high levels of low-density lipoprotein cholesterol, and metabolic syndrome are some of its major risk factors. IAS may be associated with transient or definite neurological symptoms or can be clinically asymptomatic. Transcranial Doppler and magnetic resonance angiography are the most frequently used ancillary examinations for screening and follow-up. Computed...

Early Clinical Signs, Lesion Localization, and Prognostic Factors in Unilateral Symptomatic Internal Carotid Artery Occlusion
Conclusions: In unilateral symptomatic intracranial carotid artery occlusion, poor prognosis and high mortality–associated territorial stroke pattern is frequently observed. Besides, presence of severe stenosis or occlusion and absence of collateral circulation in MCA are associated with poor prognosis.

Large Amount of Cannabis Ingestion Resulting in Spontaneous Intracerebral Hemorrhage: A Case Report
Although multiple cases of cannabis-associated ischemic stroke have been reported, there are only 2 reported cases of hemorrhagic stroke with an associated cerebral vasoconstriction. To our knowledge, we present the first case of basal ganglia hemorrhage after a large-volume oral ingestion of cannabis without other identified risk factors. In our case, cerebral digital subtraction angiography within 24 hours of presentation did not reveal vasoconstriction leading to a possible alternative explanation for hemorrhagic stroke, including cannabis-induced transient arterial hypertension and autoregulation disruption.

Recurrent Intracerebral Hemorrhage in Patients With Hypertension is Associated With APOE Gene Polymorphism: A Preliminary Study
This study evaluates the roles of apolipoprotein E (APOE) and α-1 antichymotrypsin (ACT) genes in patients with recurrent hypertensive ICH and compares patients with nonrecurring hypertensive ICH and normal controls.Methods: Thirty-three recurrent and 101 nonrecurrent patients with hypertension and ICH were included. The demographic, stroke risk factors, and computed tomographic or magnetic resonance imaging findings were recorded. Magnetic resonance angiography or digital subtraction angiography and vasculitic profile were done in recurrent group to exclude secondary causes of ICH. APOE and ACT gene polymorphisms were as...

Cerebral Perfusion Change of Venous Hypertension on Near-Infrared Spectroscopy Signals after Operation for Dural Arteriovenous Fistula
We report 1 case of dural AVF with retrograde leptomeningeal venous drainage. Cerebral hemodynamics were monitored using near-infrared spectroscopy imaging before, during, and after the 2-stage operative treatment. Preoperative functional near-infrared spectroscopy (fNIRS) showed an increase in deoxyhemoglobin (HbR) during a motor task. After partial coil embolization of the shunt points (stage 1), HbR increased during the first half of the task and decreased later, whereas oxyhemoglobin (HbO2) decreased in the first half of the task and increased later. After complete embolization (stage 2), fNIRS showed a pattern similar...

Report of Dramatic Improvement after a Lumboperitoneal Shunt Procedure in a Case of Anticoagulation Therapy-Resistant Cerebral Venous Thrombosis
Cerebral venous thrombosis (CVT), which typically progresses from either acute or subacute onset, presents with symptoms related to intracranial hypertension (e.g., headache and papilledema) and brain parenchymal lesions (e.g., aphasia and hemiplegia). Anticoagulation therapy is generally accepted as a treatment for CVT and often leads to good clinical outcomes. However, we experienced a case of CVT with an uncommon clinical course. The patient was a 63-year-old man who presented with headache, papilledema, visual loss, and diplopia; his condition gradually deteriorated, and he was diagnosed with CVT via cerebral angiography.
