Vessel perforation during withdrawal of Trevo ProVue stent retriever during mechanical thrombectomy for acute ischemic stroke.
Abstract
The authors report a case of an intracranial extravasation during the withdrawal of a Trevo ProVue stent retriever device in a patient being treated for acute ischemic stroke. An 82-year-old woman developed sudden left hemiparesis and aphasia during an urgent cardiac catheterization procedure for a non-ST elevation myocardial infarction. She had a baseline National Institutes of Health Stroke Scale (NIHSS) score of at least 10 and no improvement with intravenous administration of tissue plasminogen activator (tPA). Cerebral angiography was performed with conscious sedation, confirming an occlusion of the ...

The Case Files: Traumatic Carotid Dissection
By Hsiao, Jonie MD
A 30-year-old man who was right-hand dominant presented 10 days after sustaining left-sided face and head trauma from a fall from a skateboard at an unknown speed. He lost consciousness for several seconds, and initially developed a headache with nausea and vomiting. A non-contrast head CT performed at another hospital done two days after the incident was reportedly negative.
He now presents primarily with concerns about the appearance of his left eye. He has notable anisocoria and a droopy eyelid. His left pupil is notably smaller, 2 mm, compared with the right eye, 5 mm. Both are reactive. The re...

Intravenous Thrombolysis Resulting In Acute Ischemic Stroke Recanalization Can Lead To Cerebral Hyperperfusion Syndrome (P7.123)

Intracranial Dural Arteriovenous Fistula Presenting with Recurrent Transient Fluent Aphasia (P2.097)
Conclusion: This case illustrates that a vascular malformation can present with recurrent transient focal deficits. A well-defined hypodensity with increased vascularity is an uncommon early finding in acute ischemic stroke. In the setting of recurrent neurological deficits, these findings should prompt a thorough neurovascular evaluation.Disclosure: Dr. Nourbakhsh has nothing to disclose.

Amusia: Unique Presentation of Stroke (P6.261)
CONCLUSIONS:Even though music and speech are similar in principle and execution they are functions of different hemispheres of the brain. Unlike aphasia, anatomical localization of amusia has not been established but it is known that right non dominant hemisphere is concerned with musical ability. Impairment of musical ability in the presence of intact speech can be the only presenting finding in stroke. Their identification is the key to early and appropriate treatment.Study Supported by:NoneDisclosure: Dr. Ramchandani has nothing to disclose. Dr. Alsmaan has nothing to disclose.

Basilar TIAs of Symptomatic Carotid Artery Stenosis (P7.168)
CONCLUSIONS: Otherwise unexplainable Basilar TIAs maybe manifestations of significant Carotid artery disease and should be treated as symptomatic Carotid artery stenosis.Study Supported by: Self-supported.Disclosure: Dr. Veloso 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.

Intracerebral Hemorrhage Associated with Oral Phenylephrine Use (P5.138)
CONCLUSION: It is scientifically plausible that Phe may cause strokes given that it is consistent with the pharmacological properties and adverse event profiles of similar amphetamine-like sympathomimetics. As RCVS has been well-described in association with over the counter sympathomimetics, these lines of evidence support a likely, although not definitive, causal relationship between Phe and ICH.Disclosure: Dr. Tark has nothing to disclose.

Design and Validation of a Prehospital Stroke Scale to Predict Large Arterial Occlusion: The Rapid Arterial Occlusion Evaluation Scale Clinical Sciences
Conclusions—
The RACE scale is a simple tool that can accurately assess stroke severity and identify patients with acute stroke with large artery occlusion at prehospital setting by medical emergency technicians.

Recognition and evaluation of nontraumatic subarachnoid hemorrhage and ruptured cerebral aneurysm.
Abstract
Swift diagnosis and treatment are critical for good outcomes in patients with nontraumatic subarachnoid hemorrhage, which is usually caused by a ruptured aneurysm. This type of stroke often results in death or disability. Rates of misdiagnosis and treatment delays for subarachnoid hemorrhage have improved over the years, but these are still common occurrences. Subarachnoid hemorrhage can be more easily diagnosed in patients who present with severe symptoms, unconsciousness, or with thunderclap headache, which is often accompanied by vomiting. The diagnosis is more elusive in patients who present in good c...

A single-site retrospective study of pediatric arterial ischemic stroke etiology, clinical presentation, and radiologic features.
CONCLUSIONS: PAIS occurs more frequently in younger children and this group most frequently presents with convulsion as the initial symptom. The overall etiologies of PAIS may be different from those of adult stroke and the involved regions may be distinguishing features of PAIS or its different forms, but more research is required.

Teaching NeuroImages: Treatment-resistant rapidly progressive amyloid {beta}-related angiitis
A 76-year-old woman presented with 1 month of progressive aphasia, headache, and subsequent right hemiparesis. Initial brain MRI showed a punctate infarct (figure 1, A and C). Susceptibility-weighted imaging was unremarkable. A repeat study 16 days later demonstrated bihemispheric infarcts with multifocal attenuation of intracranial vessels on magnetic resonance angiography (figure 1, B and D). CSF showed a lymphocytic pleocytosis (101 leukocytes/µL) and elevated protein (480 mg/dL). Brain biopsy showed granulomatous angiitis with amyloid deposition and fibrinoid necrosis surrounded by inflammatory cells (figure 2). ...

Fatal Multiple Systemic Emboli after Intravenous Thrombolysis for Cardioembolic Stroke
Our objective is to present a case of fatal multiple systemic emboli after intravenous thrombolysis for cardioembolic stroke. A 64-year-old woman with atrial fibrillation was admitted for evaluation of sudden consciousness disturbance, right hemiplegia, and aphasia. Diffusion-weighted imaging showed no early ischemic changes of the brain, and magnetic resonance angiography (MRA) showed occlusion of the left middle cerebral artery (MCA). One hour after initiation of 0.6 mg/kg of intravenous alteplase, the MCA was partially recanalized. Her symptoms disappeared the following day. We began intravenous heparin for secondary pr...

Acute stroke secondary to carotid artery dissection in a patient with germ cell tumour: did Cisplatin play a role?.
Conclusion: Carotid artery dissection has not been reported as the cause of cisplatin-associated stroke in patients with GCT. This case demonstrates the potential for cisplatin-induced mechanisms causing carotid dissection, particularly considering the close temporal association of BEP and the event in our patient. In young patients with excellent curative potential from GCT, every effort should be made to minimise the risk of disabling side effects of BEP. After a stroke, imaging of intracranial and extracranial arteries, monitoring and correction of serum magnesium is recommended. The decision to continue or discontinue ...

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...
