Effects of total saponins from Trillium tschonoskii rhizome on grey and white matter injury evaluated by quantitative multiparametric MRI in a rat model of ischemic stroke
Conclusion Our results suggested the potential protective and repair-promoting effects of TSTT on grey and white matter from damage induced by ischemia. This study provides a modern pharmacological basis for the application of TSTT in managing ischemic stroke. Graphical abstract

Yield of Computed Tomography (CT) Angiography in Patients with Acute Headache, Normal Neurological Examination, and Normal Non Contrast CT: A Meta-Analysis
Patients with acute severe headache, normal neurological examination, and a normal noncontrast head computed tomography (NCCT) may still have subarachnoid hemorrhage, cerebral venous thrombosis (CVT), cervical arterial dissection, or reversible cerebral vasoconstriction syndrome (RCVS). Computed tomography angiography (CTA) is used increasingly in the emergency department for evaluating this, but its added value remains controversial.

Recurrent Stroke in a Young Woman with a Single Pulmonary Arteriovenous Fistula: An Unusual Association
Conclusions: This case highlights the importance of search, identification, and interpretation of causes of cryptogenic strokes to better choose therapy to reduce the stroke recurrence risk. Although unusual, PAVF detection is a treatable cause of stroke and the therapeutic decisions should take into account the characteristics of the PAVF and the degree of suspicion regarding the cause-effect relationship between PAVF and stroke.Case Rep Neurol 2017;9:293 –298

Agenesis of the Left Internal Carotid Artery Associated with Dolichoectatic Intracranial Arteries
A 28-year-old man without a significant medical history visited our hospital complaining of a headache. Computed tomography (CT) demonstrated thick, calcified vertebral artery (VA) and basilar artery (BA), despite the patient being young. Magnetic resonance angiography demonstrated the absence of the left internal carotid artery (ICA). The right ICA, the bilateral VA, and the BA were well developed and dolichoectatic. CT revealed the absence of the carotid canal on the left side. The condition was diagnosed as congenital agenesis of the left ICA with dolichoectatic changes in 3 other arteries.

Headache and pregnancy: a systematic review
AbstractThis systematic review summarizes the existing data on headache and pregnancy with a scope on clinical headache phenotypes, treatment of headaches in pregnancy and effects of headache medications on the child during pregnancy and breastfeeding, headache related complications, and diagnostics of headache in pregnancy. Headache during pregnancy can be both primary and secondary, and in the last case can be a symptom of a life-threatening condition. The most common secondary headaches are stroke, cerebral venous thrombosis, subarachnoid hemorrhage, pituitary tumor, choriocarcinoma, eclampsia, preeclampsia, idiopathic ...

Teaching NeuroImages: Artery of Percheron thrombosis causing selective downgaze palsy
A 47-year-old man with migraines presented with sudden onset of vertical diplopia, dysarthria, right facial weakness, and downgaze palsy (figure 1). Brain MRI revealed ischemic strokes in the midbrain periaqueductal gray, bilateral thalamic–midbrain junction, and thalamus (figure 2, A–C). Gradient echo and T1 MRI showed hypointensity in the interpeduncular fossa (figure 2, D and E). No flow could be visualized in this structure on CT angiogram or catheter angiogram, demonstrating a thrombosed artery of Percheron (figure 2, F–H). Downgaze palsy, which improved 18 months later, may result from bilateral les...

Teaching NeuroImages: RCVS causing simultaneous convexity subarachnoid hemorrhage and hemimedullary infarction
A 34-year-old previously healthy man presented with thunderclap headache, dysphagia, dysarthria, and oscillopsia. Neurologic examination revealed right-beating nystagmus, dysphagia, hypophonia, right hemianesthesia, and left hemiparesis. Brain imaging showed convexity subarachnoid hemorrhage (figure 1A) and left hemimedullary infarct (figure 1B). Catheter angiography showed tapering of left vertebral artery and diffuse segmental vasoconstriction (figure 2). Routine serum and CSF results were unremarkable. Thorough infectious, immunologic, and coagulopathy workup was negative. Reversible cerebral vasoconstriction syndrome (...

Intra-arterial milrinone may differentiate fulminant RCVS from vasculitis
A 39-year-old woman taking a monoamine oxidase inhibitor presented with a 1-week history of severe non-thunderclap headache and visual field deficits. Brain CT showed infarcts in both parietal lobes, with narrowing of intracranial vessels on CT angiogram (figure 1), suggesting either vasculitis or reversible cerebral vasoconstriction syndrome (RCVS). Despite treatment with both methylprednisolone and nimodipine, she experienced progressive aphasia and right leg weakness. She underwent an urgent cerebral angiogram (figure 2), during which intra-arterial milrinone reversed both the vasoconstriction and its symptoms, thereby ...

Acute ischemic stroke what is hidden behind?
We present a case of a 58-year-old male patient that presented to ED with sudden onset of headache and left-sided hemiparesis, computed tomography (CT) demonstrated an ischemic stroke of the right middle cerebral artery. When the question of whether to start r-TPA or mechanical thrombectomy was discussed, a cardiac point-of-care ultrasound was performed in ED and showed a type A aortic dissection; immediately a CT aortic angiogram was performed and confirmed the diagnosis. The patient was taken to theater and had a favorable outcome. <Learning objective: Acute aortic dissection (AAD) may present as acute ischemic st...

SMART syndrome with cerebral angiographic abnormalities - A case report
Black et al. first used the terminology ‘stroke-like migraine attacks after radiation therapy (SMART) syndrome’ and proposed diagnostic criteria in 2006 [1]. Proposed diagnostic criteria are remote history of cerebral radiotherapy, prolonged but reversible signs and symptoms referable to a unilateral cortical region and nearly reversi ble diffuse gyral and leptomeningeal enhancement within the symptomatic area [2]. However, these criteria do not include angiographic features. To the best of our knowledge, our case is the first report to show vascular change by means of digital subtraction angiography.

Isolated intracranial fibromuscular dysplasia of the posterior cerebral artery
We report a patient with FMD involving the posterior cerebral arteries (PCAs). A 24year old female was presented with a 4day history of right homonymous hemianopsia with throbbing headache in the left temporo-occipital area. The brain magnetic resonance imaging (MRI) revealed an acute ischemic stroke in the left PCA territory, while the Time of Flight (TOF) magnetic resonance angiogram (MRA) showed segmental luminal irregularities in the left proximal PCA. The conventional angiogram revealed the “string of beads” appearance, a characteristic that is pathognomonic for FMD. The patient’s inhospital clinical course was ...

CONCLUSIONS: Surgical revascularization may be useful to reduce the moyamoya vessels and prevent cerebrovascular events in a certain subgroup of patients with asymptomatic moyamoya disease, although its universal benefits on asymptomatic moyamoya disease have not been established yet.

Migraine and Cerebrovascular Atherosclerosis in Patients With Ischemic Stroke Brief Report
Conclusions—Migraine is not associated with excess atherosclerosis in large vessels in patients with acute ischemic stroke. Our findings suggest that the biological mechanisms by which migraine results in ischemic stroke are not related to macrovascular cerebral atherosclerosis.
