The Basilar Artery on Computed Tomography Angiography Score for Acute Basilar Artery Occlusion Treated with Mechanical Thrombectomy
Recently, the Basilar Artery on Computed Tomography Angiography (BATMAN) score predicts clinical outcome of acute basilar artery occlusion (BAO), yet there is no extensive external validation. The purpose of this study was to validate the prognostic value of BATMAN scoring system for the prediction of clinical outcome in patients with acute BAO treated with endovascular mechanical thrombectomy by using cerebral digital subtraction angiography (DSA).

Lenalidomide-Induced Ischemic Cerebrovascular Disease in Polyneuropathy, Organomegaly, Endocrinopathy, Monoclonal Gammopathy, and Skin Changes Syndrome
We describe the case of a 34-year-old woman with polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes (POEMS) syndrome. She developed transient ischemic attack after the introduction of lenalidomide plus dexamethasone (Rd) therapy despite no vascular risk factors. Magnetic resonance and computed tomography angiographies showed bilateral internal carotid artery stenosis. Rd therapy was suspended because of its thromboembolic risk. She had been neurologically stable during the suspension of Rd therapy.

Evaluation of a CTA-Triage Based Transient Ischemic Attack Service: A Retrospective Single Center Cohort Study
We designed a computed tomography angiography (CTA)-based algorithm for patients presenting to hospital with a transient ischemic attack (TIA) which identified high-risk patients, as well as inpatient versus semiurgent outpatient management following MRI, and we hypothesised that this would be effective.

Clinical Implications of Basilar Artery Plaques in the Pontine Infarction with Normal Basilar Angiogram: A High-Resolution Magnetic Resonance Imaging Study

Persistent Primitive Olfactory Artery as Novel Collateral Channel to the Anterior Cerebral Artery in Moyamoya Disease
Background: There are a variety of collateral routes to compensate persistent cerebral ischemia in moyamoya disease. However, there is no report presenting the persistent primitive olfactory artery (POA) as a spontaneous collateral route to the anterior cerebral artery (ACA) in moyamoya disease. Methods: We precisely examined cerebral angiography in 84 patients with moyamoya disease to identify the collateral channel through the persistent POA. Its anatomy was evaluated on pre- and postoperative angiography.

Angiographic Features of Intracranial Aneurysms in Ecuador
We describe the epidemiologic and angiographic features of ruptured and unruptured IAs in a cohort of patients from Ecuador.Methods: We conducted a retrospective analysis of prospectively acquired databases from 3 different tertiary hospitals over a 3-year period (2014-2017). In a per-patient basis, odd ratios (ORs) of ruptured presentation for each variable using a univariate logistic regression model were calculated.

A High Prevalence of Intracranial Stenosis in Patients with Coronary Artery Disease and the Diagnostic Value of Transcranial Duplex Sonography
Background: According to the data from the population-based Rotterdam study, intracranial carotid artery calcification detected by computed tomography is very common and contributed to 75% of all strokes. The aim of the present study was to estimate the prevalence of intracranial stenosis (IS) using noninvasive transcranial color-coded duplex sonography (TCCS) in neurologically asymptomatic patients with coronary artery disease (CAD). Methods: Three hundred and eighty-nine patients with angiographically-confirmed, severe CAD were included prospectively.

Efficacy of Direct Revascularization Surgery for Hemorrhagic Moyamoya Syndrome As a Late Complication of Cranial Irradiation for Childhood Craniopharyngioma
Moyamoya syndrome (MMS) is an uncommon late complication after cranial irradiation. Its hemorrhagic presentation from the associated pseudo-aneurysm is extremely rare, and the optimal management strategy is undetermined. We herein report a 36-year-old man who developed intraventricular hemorrhage from a pseudo-aneurysm at the extended left anterior choroidal artery as an abnormal collateral of MMS 30 years after surgical removal and cranial irradiation for childhood craniopharyngioma. Catheter angiography confirmed the diagnosis of MMS, and multiple pseudo-aneurysms were evident at the ipsilateral abnormal choroidal collat...

Anterior Choroidal Artery Infarction Evaluated with 123I-Imp Single-Photon Emission Computed Tomography and 7 Tesla Magnetic Resonance Imaging
Anterior choroidal artery (AchA) infarction remains a challenging diagnosis although it was first described almost 100 years prior. N-isopropyl-p-[123I]-iodoamphetamine single-photon emission computed tomography (123I-IMP SPECT) and 7 Tesla magnetic resonance angiography (7T-MRA) are not routinely performed in cases of AchA infarction. Therefore, the application of 123I-IMP SPECT and 7T-MRA for AchA infarction has not been reported previously. A 67-year-old man presented with disturbed consciousness, gaze preference to the left, aphasia, right homonymous hemianopia, and right hemiparesis.

Cortical Vein Opacification for Risk Stratification in Anterior Circulation Endovascular Thrombectomy
Introduction: There is continued interest in identifying factors that predict a favorable outcome after endovascular thrombectomy (EVT) for anterior circulation large vessel occlusion (ACLVO). We compared the predictive values of 2 different scoring systems for evaluating venous collateral circulation. Methods: A retrospective review of patients who underwent EVT for ACLVO at a single institution was performed. Those who underwent preprocedural computed tomography angiography (CTA) were selected.

Spontaneous Dissection of Both Vertebral Arteries Diagnosed with Three-Dimensional T1-Weighted Image
A 48-year-old woman spontaneously developed occipital pain, without any other neurological deficit. A brain magnetic resonance angiography showed narrowing, irregular dilatation, and aneurysmal formation in both the vertebral arteries (VA). According to these findings and the clinical course, we diagnosed the patient with spontaneous VA dissection. There was no finding suggesting cerebral infarction or subarachnoid hemorrhage. Three-dimensional T1-weighted magnetic resonance imaging performed 27days after first onset of headache revealed a crescent-shaped high-intensity lesion in both the VA walls.

The Significance of Contrast Density of the Computed Tomography-Angiographic Spot Sign and its Correlation with Hematoma Expansion
The computed tomography angiographic (CTA) spot sign has been shown to predict hematoma expansion in patients with intracranial hemorrhage (ICH), but the significance of the spot sign density (SSD) and the spot sign ratio (SSR) has not yet been explored.

Left Thalamus Arteriovenous Malformation Secondary to Radiation Therapy of Original Vermian Arteriovenous Malformation: Case Report
A 70-year-old gentleman with history of hypothyroidism, hyperlipidemia, hypertension, and right superior cerebellar aneurysm presented to the neurosurgery service in 2008 with vertigo. Diagnostic cerebral angiography performed that year demonstrated a vermian arteriovenous malformations (AVM). The patient underwent stereotactic proton beam radiosurgery, which resulted in a decrease in flow and size of the lesion, and the patient was lost to follow-up. Now at the age of 80, the patient presented with acute gait instability.
