Safety and efficacy of the Neuroform Atlas for stent-assisted coiling of intracranial aneurysms: A multicenter experience
ConclusionsOur results demonstrate that treatment of intracranial aneurysms with the Neuroform Atlas stent is associated with low morbidity and a high aneurysm occlusion rate at mid-term follow-up. Further studies will be necessary to confirm our results.

Imaging After Thrombolysis and Thrombectomy: Rationale, Modalities and Management Implications
AbstractPurpose of ReviewUrgent reperfusion treatment with intravenous thrombolysis or mechanical thrombectomy reduces disability after ischaemic stroke. Imaging plays an important role in identifying patients who benefit, particularly in extended time windows. However, the role of post-treatment neuroimaging is less well established. We review recent advances in neuroimaging after reperfusion treatment and provide a practical guide to the options and management implications.Recent FindingsPost-treatment imaging is critical to identify patients with reperfusion-related haemorrhage and oedema requiring intervention. It also...

Cerebral embolism and carotid-hyoid impingement syndrome
Publication date: Available online 12 April 2019Source: Journal of Clinical NeuroscienceAuthor(s): Lay Kun Kho, Timothy R Bates, Andrew Thompson, Ferry Dharsono, David PrenticeAbstractEmbolic stroke of undetermined source (ESUS) is not uncommon in young patients. Here, we describe two cases of stroke from an unusual aetiology; cerebral embolization from carotid artery injury presumed secondary to hyoid bone impingement. Both patients demonstrated angiographic evidence of hyoid bone impingement. Following resection of the greater cornu of the hyoid bone, neither patient had further strokes.

High resolution vessel wall MR imaging in prestenotic intracranial atherosclerotic disease
We present a case of intracranial hemorrhage presumably due to intracranial atherosclerotic disease (ICAD) identified by VWI and silent on lumen-based imaging modalities. A 66-year-old female presented with sudden onset headache and dysarthria. A head CT showed intracranial hemorrhage centered in the right basal ganglia. Further imaging by CT angiography, MR angiography and a conventional catheter angiogram were negative. MRI of the brain, including VWI, showed abnormal enhancement in the right middle cerebral artery vessel wall, suggesting intracranial atherosclerotic changes in a prestenotic vessel. As a potential noninv...

Implementation of multiphase computed tomography angiography in management of patients with acute ischemic stroke in clinical practice
Publication date: Available online 19 December 2018Source: Journal of Clinical NeuroscienceAuthor(s): Nattaphol Uransilp, Pornpatr A. Dharmasaroja, Arvemas Watcharakorn, Sombat MuengtaweepongsaAbstractMultiphase computed tomography angiography (CTA) provides information on the status of major cranial arteries and extent of brain collateralization. The purpose of the study was to determine whether implementation of multiphase CTA in routine clinical practice was feasible, safe and useful. Patients with acute ischemic stroke (NIHSS ≥ 6) were included. Multiphase CTA was performed. Duration of performing multiphase CTA,...

Selective Middle Cerebral Artery Occlusion In The Rabbit: Technique And Characterization With Pathologic Findings and Multimodal MRI
ConclusionsWe demonstrate the feasibility of a rabbit model of embolic MCA occlusion with angiographic documentation. Serial MR imaging demonstrated changes comparable to those observed in human ischemic stroke, confirmed histopathologically.

Management of Blunt Cerebrovascular Injury
AbstractPurpose of ReviewThis review provides an updated summary of blunt cerebrovascular injury (BCVI) to guide clinicians in its early diagnosis and prevention and treatment of stroke associated with such injury.Recent FindingsUntreated BCVI causes stroke in 10 –40% of patients, but more than half will not present with stroke symptoms initially. Risk of stroke is highest in the first 7 days, with a peak in the first 24 h. Computed tomography (CT) angiography is currently the screening modality of choice, although digital subtraction angiography may sti ll be required in some cases. Antithrombotic therapy is the mains...

Internal carotid artery dissection without intracranial infarct following a minor shoulder trauma: The second pediatric case and review of the literature
ConclusionIn carotid artery dissections, prodromal symptoms such as transient ischemic attack, like in our patient, are rarely present in children. For good long term outcomes, it is very important to suspect, diagnose and initiate appropriate treatment in a rapid manner in carotid artery dissection before severe neurological findings such as acute ischemic stroke develops.

Moyamoya vasculopathy with anti-SCL-70 antibodies: A case report and review of the literature
We describe a patient with an ischemic stroke and angiographic findings of moyamoya in the setting of positive antinuclear antibodies and anti-Scl-70 antibodies with clinical features of scleroderma on exam. A review of current literature identified three similar cases where immunosuppression in addition to secondary stroke prevention led to reduced frequency of neurological sequelae. These cases plus our own demonstrate that patients with moyamoya vasculopathy in association with anti-Scl 70 antibodies exist on a spectrum with either predominant scleroderma features or neurological symptoms. There are a limited number of ...

Acute ischemic dissection of an “S”-shaped carotid artery: The “one-stop” value of using a detachable Solitaire AB stent
This study aimed to evaluate the efficacy and safety of endovascular repair using detachable Solitaire AB stents for acute ischemic dissection of “S”-shaped carotid arteries. From May 2015 to December 2016, a total of 127 patients with acute ischemic stroke (AIS) underwent endovascular treatment in our center. Among them, five AISs were due to acute dissection of an “S”-shaped carotid artery. Coexisting carotid embolism was identified in all five patients, who first underwent successful Solitaire AB stent-based retrieval of the embolism. All patients then underwent Solitaire AB stenting to reopen the occluded carot...

Down syndrome with moyamoya disease: A case series
Pawan Kumar, Inusha Panigrahi, Naveen Sankhyan, Chirag Ahuja, Prasoon K GoyadiJournal of Pediatric Neurosciences 2018 13(2):201-204 Down syndrome (DS), resulting from trisomy 21, is a common cause of mental retardation. Around 20,000 babies with DS are born every year in India. There is an increased risk of cerebral infarction in children with DS, the common causes being thromboembolism secondary to atrioventricular canal defects, right-to-left shunting, myocardial dysmotility, or cardiac valvular abnormalities. Stroke due to other causes can also occur in patients with DS, and one of these is moyamoya disease. This can b...

Web of the carotid artery: An under-recognized cause of ischemic stroke
We describe here an additional case of ischemic stroke caused by a carotid web in a young healthy woman. Detection of this vascular abnormality required the use of CT angiography and cerebral digital subtraction angiography. Although there is little evidence regarding the optimal management of this condition, under medical treatment with dual antiplatelet therapy our patient remained free of recurrent stroke events. This case report study illustrates that the web of the carotid artery is an uncommon cause of stroke which should always be considered and ruled out, especially in young patients with otherwise cryptogenic stro...

An Emergent Large Vessel Occlusion Screening Protocol for Acute Stroke: A Quality Improvement Initiative
Background: Nurses play an integral role in triaging stroke patients. The purpose of this quality improvement initiative was to determine the efficacy of using an emergent large vessel occlusion (ELVO) screening protocol in the emergency department by nursing staff to improve identification of eligible patients as compared with current practice, improving time to endovascular treatment. Methods: Retrospective chart review was used to identify 76 patients admitted to a large urban stroke center. Of these, 36 presented during a 4-month period before the implementation of the Stroke Vision, Aphasia, Neglect (Stroke VAN) tool ...
