A Magnetic Resonance Angiography-Based Study Comparing Machine Learning and Clinical Evaluation: Screening Intracranial Regions Associated with the Hemorrhagic Stroke of Adult Moyamoya Disease
Moyamoya disease (MMD) is a chronic occlusive cerebrovascular disease characterized by bilateral progressive steno-occlusive changes of unknown etiology at the distal portion of the internal carotid artery or proximal portion of the anterior arteries and middle cerebral arteries, accompanied by the presence of an abnormal vessel network (moyamoya vessels) at the base of the brain.1 The incidence and prevalence of MMD are increasing worldwide, which may indicate an increase in the number of MMD patients or an underestimation of the actual number of MMD patients in the past.

Endovascular Revascularization of Multi Segment Chronically Occluded ICA
This case report describes a novel endovascular method for treating chronically occluded internal carotid artery (COICA). The patient is a 55-year-old male with vascular risk factors who presented to an outside institution with right-sided weakness and dysarthria, was diagnosed as having a stroke, and discharged with medical management. The patient's symptoms failed to improve throughout the week prompting him to visit another outside institution, where computed tomography (CT) angiography showed bilateral occlusion of the ICAs at their origins extending intracranially.

Low NIHSS score large vessel occlusion caused by infective endocarditis treated with thrombectomy
A 24-year-old woman had undergone dental treatment 3 weeks before and had a mild fever for a week. She presented to the emergency department with the chief complaint of weakness in the right upper limb after waking up. She had mild paralysis of the right upper limb (National Institutes of Health Stroke Scale [NIHSS] score 1). Head magnetic resonance imaging (MRI) showed scattered infarcts in the left frontal and parietal lobes and left internal cerebral artery (ICA) occlusion (Fig. 1A, B). Cerebral angiography showed that the left ICA was occluded immediately after its origin (Fig.

Comparing the benefit of ASPECTS on maximum intensity projection images of computed tomography angiography to source images and noncontract computed tomography in predicting infarct volume and collaterals extent
In acute ischemic strokes (AIS), the Alberta Stroke Program Early Computed Tomography Score (ASPECTS) and CT perfusion (CTP) are commonly used to determine mechanical thrombectomy eligibility. Prior work suggests that CTA source image (CTA-SI) ASPECTS (CTAasp) and a newly described CTA maximum intensity projection (CTA-MIP) ASPECTS (MIPasp) better predict the final infarct core. Our goal was to compare MIPasp to CTAasp and non-contrast CT ASPECTS (NCCTasp) for predicting ischemic core and collaterals established by CTP.

Usefulness of combining CISS and digital subtraction angiography in diagnosis of isolated posterior inferior cerebellar artery dissection
A 63-year-old man was admitted to our stroke center with brain infarction in the left posterior inferior cerebellar artery (PICA) territory. The initial MRI showed no findings suggestive of arterial dissection, and post-discharge MRI showed no temporal changes. Digital subtraction angiography (DSA) revealed vasodilation of the proximal portion of the PICA but it was uncertain whether dissection was present. Discrepancy between the outer contour seen on constructive interference in steady state (CISS) MRI and the inner contour seen on DSA suggested the presence of intramural hematoma.

Correlation Between Severity of Carotid Stenosis and Vascular Reserve Measured by Acetazolamide Brain Perfusion Single Photon Emission Computed Tomography
This study examined that relationship. A total of 56 ICAs in 43 patients were included. Computed tomography scan or magnetic resonance imaging showed no evidence of infarction in any of these patients. Both iodine-123-N-isopropyl-p-iodoamphetamine (123IMP)–single photon emission computed tomography (SPECT) in the resting state and 123IMP-SPECT with acetazolamide (ACZ) enhancement were performed. Quantitated cerebral blood flow (CBF) images were acquired with the 123IMP autoradiography technique. The mean CBF without ACZ administration (resting CBF) and CVR in the middle cerebral artery territory were calculated using ste...

Haptoglobin Phenotype Predicts Cerebral Vasospasm and Clinical Deterioration after Aneurysmal Subarachnoid Hemorrhage
Vasospasm (VS) and delayed cerebral ischemia (DCI) after subarachnoid hemorrhage (SAH) are thought to greatly affect prognosis. Haptoglobin (Hp) is a hemoglobin-binding protein expressed by a genetic polymorphism (1-1, 2-1, and 2-2). Our objects were to investigate whether the Hp phenotype could predict the incidence of cerebral infarction, favorable outcome, clinical deterioration by DCI, and angiographical VS after aneurysmal SAH. Ninety-five consecutive patients who underwent clipping or coil embolization were studied. Favorable functional outcome was defined as a modified Rankin Scale score of 0-2 at 3 months. Angiogr...

Intraprocedural Prediction of Hemorrhagic Cerebral Hyperperfusion Syndrome After Carotid Artery Stenting
Hyperperfusion syndrome (HPS) is a rare but severe complication after carotid artery stenting (CAS). Reliable methods for predicting HPS remain to be developed. We aimed to establish a predictive value of hemorrhagic HPS after CAS. Our retrospective study included 136 consecutive patients who had undergone CAS. We determined the cerebral circulation time (CCT) by measuring the interval between the point of maximal opacification of the terminal portion of the internal carotid artery and the cortical vein. We calculated intraprocedural CCT changes (ΔCCT) by subtracting postprocedural CCT values from preprocedural CCT values...

Assessment of Moyamoya Disease Using Multidetector Row Computed Tomography
The recent introduction of multidetector row computed tomography (MDCT) scanners has enabled high-resolution 3-dimensional reconstruction. The purpose of this study was to establish a method to evaluate moyamoya disease using computed tomography angiography (CTA), specifically MDCT. Twenty-four patients (48 sides total) with moyamoya disease diagnosed by magnetic resonance angiography (MRA) were evaluated by means of CTA using MDCT by 3 independent observers, and the resulting 144 sides were analyzed. CTA and MRA were compared in terms of the steno-occlusive changes exhibited in each vessel. CTA and MRA scores were assigne...

Angiogram-Negative Subarachnoid Hemorrhage: Outcomes Data and Review of the Literature
We report data for 31 patients who presented to our institution from 2006 to the present. We performed a retrospective chart review, and report outcome data that include rates of rehemorrhage, hydrocephalus, vasospasm, permanent ischemic deficits, headaches, and outcomes based on modified Rankin Scale scores. We also performed a review of the literature and meta-analysis of the data therein. We compared rates of complications in the PMH subgroup and the diffuse-type hemorrhage subgroup. The chart review revealed no poor outcomes and no rehemorrhages in the patients with PMH. In the diffuse hemorrhage subgroup, 1 patient ha...

The Effect of Carotid Endarterectomy on Cerebral Blood Flow and Cognitive Function
This study aims to characterize changes in cerebral blood flow after carotid endarterectomy and to determine if patients with improvement in cerebral blood flow have improved cognitive function after endarterectomy.Methods: Cerebral blood flow was measured preoperatively and 1 month postoperatively using phase contrast magnetic resonance angiography. Preoperative flow impairment was defined as ipsilateral flow at least 20% less than contralateral flow. Improvement in flow was defined as an absolute increase of at least 0.10 in flow ratio from pre- to postoperative assessments. Patients underwent cognitive testing preoperat...
