Aetiology of Stroke in a Young Cohort: A Longitudinal Study (P1.112)
Conclusions: This descriptive study reinforces the different aetiologies encountered in strokes in those under age 65 years. In this group, especially those under 45 years, large vessel atherosclerosis accounts for a smaller proportion and more unusual aetiologies must be sought with more extensive haematological and cardiological investigations.Disclosure: Dr. Lockhart has nothing to disclose.

Institution of Code Neuro-Intervention and Its Impact on Reaction and Treatment Times (P2.312)
Conclusion: Institution of Code Neurointervention significantly improved time to treatment during work hours as compared to off hours. Rapid assembly of the neurointervention team, rapid availability of imaging and angiography suite, and greater number of resources during work hours likely contribute to these differences. Using these lessons will aid in improving stroke care for patients.Disclosure: Dr. Brar has nothing to disclose. Dr. Korya has nothing to disclose. Dr. Mehta has nothing to disclose.

Radiotherapy Induced Atherosclerosis and Stroke Syndrome (RIASS) Causing Bilateral Vision Loss and Multifocal Strokes. A Case Report and Literature Review (P4.358)
Conclusions: Evidence-based guidelines for the management of asymptomatic and symptomatic RIASS are lacking. We recommend periodic surveillance with carotid duplex scan for early diagnosis and implementation of effective stroke-prevention therapies. Most studies are retrospective surgical case series on patients with extracranial carotid stenosis (ECS) and favor either stenting or endarterectomy. Neither approach is clearly superior, as no head-to-head trial comparing both procedures in this context exists. Bypass surgery has been used in cases of HNXRT associated ECS but the long term effect has not been demonstrated. Aty...

Ischemic Stroke After Plasma Donation (P4.365)
Conclusions: Plasma donation may result in arterial thrombosis in patients with a mild hypercoagulable disorder, which is otherwise not phenotypically expressed. Further studies are needed to evaluate plasma donation as a potential etiology for ischemic stroke.Disclosure: Dr. Salahuddin has nothing to disclose. Dr. Hussaini has nothing to disclose.

Intracranial Fibromuscular Dysplasia in a Middle-Aged Woman with Recurrent Ischemic Stroke (P4.388)
Conclusions: FMD is a rare disease and has very rarely been described in the intracranial arteries. This case illustrates the natural history and progression of FMD in this patient and elucidates the limited treatment options for preventing disease progression and secondary complications. FMD most predominantly affects younger to middle-aged females and if the disease process goes unrecognized it can have devastating consequences. It is important to continue research endeavors into the genetic and biologic determinants of FMD in order to develop better prevention and therapeutic strategies for this condition.Disclosure: Dr...

Teaching NeuroImages: Dynamic vertebral artery insufficiency
A 20-year-old healthy man presented with transient right upper monoparesis and brain MRI (figure, A) demonstrated left thalamic infarct. He presented 2 weeks later with left hemiparesis at basketball practice and right thalamic infarct (figure, B). Stroke risk factor workup was unrevealing. Conventional angiography demonstrated normal left vertebral artery course (figure, C and E), but dynamic left vertebral artery occlusion during 36° rightward head turn (figure, D and F). Bow hunter syndrome, first described in an archer,1 is eponymous for positional occlusion of the vertebral artery. This is associated with strokes ...

Neurotoxocariasis, a treatable infectious etiology of Stroke (P3.318)
Conclusions:Toxocara infection is an uncommon but treatable etiology of stroke, and should be particularly considered in patients with eosinophilia, positive serology, myocarditis and embolic strokes.Disclosure: Dr. Garcia Monco has nothing to disclose.

Vasa Vasorum Enhancement on Computerized Tomographic Angiography Correlates with Symptomatic Patients with 50% to 70% Carotid Artery Stenosis (P4.259)
Conclusions:In patients with 50% to 70% ICA stenosis, VV enhancement recognized on computed tomographic angiography is strongly associated with acute neurological symptoms compared with calcified and nonenhancing-noncalcified arterial plaques. This finding may aid in the identification of patients at increased risk for ischemic stroke within populations with the same degree of stenosis.Disclosure: Dr. Pizzolato Umeton has nothing to disclose.

Role of Pial Collateral Flow in Acute Ischemic Stroke Outcomes (P5.273)
Conclusions:In the patients with acute ischemic stroke due to MCA occlusion, better collaterals on the DSA are independently associated with improved neurological outcome at 24–48 hour after ET and at the time of discharge. This concept needs to be explored further in a larger dataset that will also include additional imaging parameters.Disclosure: Dr. Modi has nothing to disclose. Dr. Marin has nothing to disclose.

Bilateral vertebral artery dissection, agenesis of both ICAs, and connective tissue aberrations
A 35-year-old woman presented with acute signs of stroke (appendix e-1 on the Neurology® Web site at www.neurology.org). After initial CT with angiography, MRI with time-of-flight angiography confirmed agenesis of both internal carotid arteries (ICA; figure 1A). It revealed bilateral vertebral artery (VA) dissections and ischemias in both middle artery territories (figure 1, A–E). Skin biopsy microscopy (figure 2) was consistent with ultrastructural connective tissue syndrome (uCTD), for which no further evidence was found apart from mild hypermobility of the finger joints. The underlying uCTD with structural ins...

A Unique Presentation of Pediatric Stroke Attributed to Intrathecal Methotrexate (P3.309)
CONCLUSIONS:This is a rare case of ischemic watershed infarcts with diffuse reversible cerebral vasospasm, after intrathecal methotrexate. This highlights the need for further research into the pathogenesis of methotrexate neurotoxicity including endothelial damage.Study Supported by:Disclosure: Dr. Ilyas has nothing to disclose.

Homocysteine, small-vessel disease, and atherosclerosis: An MRI study of 825 stroke patients
Conclusions: Hyperhomocysteinemia was associated with SVD of the brain and LVD of cerebral arteries. The MTHFR C677T polymorphism was not related to SVD and LVD, although the TT genotype was an important determinant of hyperhomocysteinemia.

Recanalization and initial poor collateral circulation determine the effect of collateral recruitment on functional outcomes. (P3.068)
Conclusion: Delayed collateral recruitment results in higher mortality. Pre-thrombolysis collateral status and recanalization of the occluded artery are important determinants of how intracranial collateral evolution affects functional outcome in IV-tPA treated AIS patients.Disclosure: Dr. Tan has nothing to disclose.
