Reversible Cerebral Vasoconstriction Syndrome Presenting as Coma (P4.354)
Conclusions: RCVS rarely can present with coma and multifocal infarctions. Exact pathophysiology remains unknown but disruption of sympathetic tone and endothelial dysfunction have been implicated. A high index of suspicion is required to minimize disease complications and prevent improper withdrawal of care.Disclosure: Dr. Khan has nothing to disclose. Dr. Adcock has nothing to disclose.

Internal Carotid Artery Stenosis and Flow Diversion: Relationship with Headache (P6.099)
Conclusion: Recognition of flow-diversion into the ECA as a possible mechanism for headaches may help in further understanding of ICA disease, its progression, and effects of carotid revascularization on quality of life. Headache as a likely surrogate marker of carotid stenosis with flow-diversion warrants more research, and may be critical in the early identification of significant ICA stenosis and prevention of TIA or stroke.Disclosure: Dr. Herial has nothing to disclose.

Predicting growth of brain aneurysms
In their article "The ELAPSS score for prediction of risk of growth of unruptured intracranial aneurysms," Backes et al.1 developed a risk score for aneurysm growth. They followed 1,507 people who had 1,909 unruptured intracranial aneurysms (some people had more than 1 aneurysm). The patients were from several medical centers around the world: Canada, the Netherlands, Finland, China, and Japan. They were all over 18 years old. Their aneurysms were followed by several types of imaging: some centers used MRI, while others used CT angiography, or calibrated digital subtraction angiography. The local doctor decided how of...

Recurrent ischemic strokes as the initial presentation of thrombotic thrombocytopenic purpura with normal platelets: a case report. (P1.296)
Conclusions:Recurrent strokes in multiple vascular territories should prompt suspicion of hypercoagulable, cardioembolic, or vasculitis/opathy. TTP can be a cause of hypercoagulability in patients with cryptogenic stroke even without major hematologic abnormalities. TTP is treatable with plasma exchange and immunosuppression. Thus, one must consider TTP even in the absence of hematologic abnormalities, especially in a young patient with no stroke risk factors and otherwise negative stroke work-up.Disclosure: Dr. Horton has nothing to disclose.

Assessment of large vessel posterior circulation thrombus with MRI and noncontrast CT. (P6.286)
Conclusions:Hyperdense sign on reformatted thin-sliced CT head and blooming artifact on GRE MRI brain in patients with LVO can be used to characterize the composition of thrombus, which could be helpful in deciding medical therapy.Disclosure: Dr. Mehta has nothing to disclose.

Can Patient or Arterial Characteristics Guide the Choice between Carotid Angioplasty and Carotid Endarterectomy? The Carotid Revascularization Endarterectomy Versus Stenting Trial (CREST) (P01.225)
CONCLUSIONS: Beyond the previously described differential treatment efficacy by age, there were no other patient or arterial characteristic detected to identify patient subgroups that would differentially benefit from the choice of CAS versus CEA. Our inability to identify factors to guide treatment choices could be due to the low number of stroke and death events, incomplete information regarding arterial characteristics in the CEA population, or the potential exclusion of "high risk" groups (such as those with severe arterial tortuosity) from the study.Disclosure: Dr. Moore has nothing to disclose. Dr. Roubin has receive...

Primary Central Nervous System Vasculitis Triggered by Cytomegalovirus Encephalitis (P01.231)
CONCLUSIONS: Our case is the first reported case in the literature of proven CMV encephalitis triggering a subsequent non-infectious CNS vasculitis probably secondary to an autoimmune response. The absence of findings in the initial MRIs of the brain in spite of an intermittently symptomatic patient and the subsequent development of ischemic infarcts supports the theory of intermittent focal hypoperfusion, finally leading to infarction. The high clinical suspicion even with lack of clear evidence of the disease process and empirical treatment led to a successful clinical recovery.Disclosure: Dr. Rosales has nothing to disc...

Early Spontaneous Recanalization of Symptomatic Carotid Occlusion: When Should We Be Looking? (P01.238)
CONCLUSIONS: Spontaneous recanalization of an occluded carotid artery may occur in a subacute fashion. Clinical deterioration, even minor, should prompt an investigation into possible recanalization.Disclosure: Dr. Cutting has received personal compensation for activities with F1000.

Prevalence of Cerebrovascular Events in Extraluminal Protruding Intracranial Atherosclerotic Plaques: Analysis of Intracranial Vessels from the Nun Study (P03.009)
CONCLUSIONS: Outside protruding plaques without angiographic stenosis appear to be responsible for ischemic events in patients with cryptogenic stroke. Higher prevalence of stroke in these patients warrants the use of newer imaging modalities like high resolution magnetic resonance imaging to identify patients who are at high risk of cerebrovascular events.Disclosure: Dr. Semaan has nothing to disclose.

Is Intracranial Arterial Involvement A Subgroup of Neuro-Behcet Syndrome? (P5.035)
Conclusion:Neurological involvement in BS patients is generally due to venous inflammation. Intracranial arterial involvement in NBS is rare, but it should be kept in mind that it can occur during the course of the disease independent of other stroke risk factors.Disclosure: Dr. Zeydan has nothing to disclose.

Spinning Out of Control: The Black Box of Basilar and Hemiplegic Migraine (P7.176)
CONCLUSIONS:In this retrospective study, triptans were used effectively with no subsequent vascular events for the abortive treatment of migraines with basilar and hemiplegic features. This data also suggests that beta blockers, tricyclic anti-depressants, anti-convulsants, and Botox injections have some efficacy in the treatment of migraines with basilar type and hemiplegic features.Disclosure: Dr. Krel has nothing to disclose.

Delays in Diagnosis and Treatment of Central Nervous System Vasculitis Lead to Poor Outcomes. (P2.294)
CONCLUSIONS: We found that increased days to diagnosis and treatment of CNS vasculitis led to neurologic worsening. These findings suggest that a more efficient protocol is needed to evaluate CNS vasculitis, and that treatment should not be delayed. Our study is limited by a small sample size and lack of long term outcomes, and prospective investigation is warranted.Disclosure: Dr. Jagolino has nothing to disclose.

Acute and Long-term Management of Symptomatic Internal Carotid Artery Dissection in the Setting of Newly Diagnosed Cerebral Amyloid Angiopathy: To Anticoagulate, or Not to Anticoagulate? (P5.155)
CONCLUSIONS:The incidence of CAA is age dependent, with sporadic cases rarely affecting individuals younger than 65 years old. While it is strongly advised that those with CAA avoid antithrombotic therapy for risk of intracerebral hemorrhage, our case poses a unique threat given his age and symptomatic carotid artery occlusion. There are no such guidelines that address antithrombic therapy in the setting of an acute ischemic stroke secondary to extracranial dissection, concurrent with cerebral microhemorrhages. Our patient was initially started on anticoagulation therapy before being discharged on an antiplatelet regimen w...

Utility of Immediate CT-angiograpahy after Intracerebral Hemorrhage (S39.004)
Conclusions: In the absence of other features suggesting a secondary cause, the results of an immediate CTA did not alter the emergent management of any of a consecutive series of patients with an ICH. Vascular imaging can often be safely delayed until after the acute period in these patients.Disclosure: Dr. Kaskar has nothing to disclose.
