An Unusual Cause Of Recurrent Ischemic Stroke: Trousseau's Syndrome From Gastric Cancer (P4.231)
CONCLUSIONS: Trousseau’s Syndrome must be considered in those presenting with recurrent strokes with an otherwise negative embolic work up especially in the elderly and those with cancer risk factors. It must prompt the clinician to look for an associated malignancy.Disclosure: Dr. JADEJA has nothing to disclose. Dr. Johnson has nothing to disclose. Dr. Soetanto has nothing to disclose.

Susceptibility Weighted MRI and Regional Cerebrovascular Reservoir Capacity in Angiography Proven Large Artery Disease in Acute Ischemic Stroke and Transient Ischemic Attack (P6.247)
CONCLUSIONS:Cortical vessel signs on susceptibility-weighted image have an association with regional cerebrovascular reservoir capacity. And this snapshout image would be a useful tool in the real world of clinical practice in evaluating cerebrovascular perfusion status. But longer follow up in much larger populations are needed.Disclosure: Dr. Lee has nothing to disclose. Dr. Won has nothing to disclose. Dr. Yoo has nothing to disclose.

"Spicy Strokes": Synthetic Cannabis and Strokes in Young (P7.123)
CONCLUSIONS: Our case is unique that there was an association between the use of synthetic cannabis and presentation of stroke. However, the JWH-018 that was previously implicated in the stroke causation was absent. More extensive research is needed in future to find other metabolites and contaminants of street preparation of ‘spice’ that may potentially cause strokes.Disclosure: Dr. El Kouzi has nothing to disclose.

Severe MCA stroke without MCA occlusion?: Thrombectomy uncovers accessory middle cerebral artery
A 21-year-old woman presented with dysarthria and severe left-sided hemiparesis. CT angiography detected a thrombus at the right distal internal carotid artery, but a well-perfused middle cerebral artery (MCA). The mechanism of the clinical presentation was therefore uncertain. IV thrombolysis was performed but she did not improve. Subsequent thrombectomy uncovered an accessory MCA originating from the A1 segment (figure 1). Neurologic deficits improved promptly and MRI demonstrated a lenticulostriate infarction (figure 2). Accessory MCA is an anatomical variant occurring in 0.4%.1 This case illustrates that knowledge of r...

Stroke Due to Air Embolism Related to Laser Ablation of Accessory Vein (P4.357)
Conclusions: Air embolism leading to devastating stroke may occur few hours after laser treatment of varicose veins. Chest symptoms associated with the procedure should raise the possibility of air embolism. Immediate therapeutic measures like 100[percnt] oxygen, hyperbaric oxygen chamber and/or hypothermia should be considered to prevent neurologic complications.Disclosure: Dr. Kale has nothing to disclose.

Collateral Blood Flow Availability in Acute Ischemic Stroke: A Case Report (P4.360)
Conclusion: This case supports earlier autopsy specimen dissections indicating most borderzone collaterals linking to adjacent vascular territories are too small to generate the immediate flow needed to spare tissue proximal to a middle cerebral stem occlusion. Assuming acute vasodilation is possible for these vessels, the acute use of vasodilators such as nitroglycerin or hydralazine and calcium-channel blockers like Nimodipine could provide an area for future study.Disclosure: Dr. Rostanski has nothing to disclose.

Teaching NeuroImages: Intracranial vertebral dissection in a 15-year-old boy with sickle cell disease
A 15-year-old boy with sickle cell disease became unresponsive after sudden-onset headache. There was no antecedent trauma. A head CT scan demonstrated subarachnoid hemorrhage at the medulla (figure). Magnetic resonance angiography of the head and neck identified the patient's known bilateral internal carotid artery stenosis (a moyamoya-like arteriopathy associated with stroke in sickle cell disease) and a new right vertebral artery dissection, which was confirmed on conventional angiography (figure). Prior MRI performed as part of routine cerebral monitoring did not reveal any preexisting abnormality of the vertebral artery.

Endovascular Therapy for Acute Ischemic Stroke with Distal Middle Cerebral Artery Occlusion; A Case Series (P3.300)
Conclusions:Our initial experience suggests that successful recanalization of M2 and M3 occlusion with EVT is feasible and safe. Larger studies would help identifying benefit of EVT in this subset of intracranial occlusions.Disclosure: Dr. Suriya has nothing to disclose. Dr. Quadri has nothing to disclose.

Thrombectomy Outcomes in Acute Ischemic Stroke due to Middle Cerebral Artery M2 Occlusion with Stent-Retriever, Aspiration, and MERCI: Multi-Center Experience (P5.251)
Conclusions:Thrombectomy for AIS patients with MCA M2 ELVO with Stent-retriever appears to be feasible with a significantly higher rate of recanalization, lower sICH rate, and favorable 90-day mRS when compared to Aspiration and MERCI.Disclosure: Dr. Atchaneeyasakul 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.

Is Achondroplasia Linked to Stroke? (P6.265)
CONCLUSIONS:This case shows an interesting correlation between achondroplasia and carney complex related myxomas that has not been described in literature before. Achondroplasia is an autosomal dominant mutation in FGFR3 gene on chromosome 4P. Mutaions in carney complex are also described to be autosomal dominant mostly involving chromosome 17q23-q24 . There has been no clear pathogenesis described pertaining this correlation yet but more genetics have to be explored.Study Supported by:Disclosure: Dr. Kaur has nothing to disclose.

Futile Revascularization after Mechanical Thrombectomy for Acute Ischemic Stroke: Pooled Analysis of the Multi MERCI, TREVO and TREVO 2 Trials (S35.004)
Conclusions: Futile revascularization is relatively frequent in patients treated by mechanical thrombectomy, particularly among those were older or with severe neurological deficits. Further studies are needed to elucidate the predictors of FR in patients treated with Trevo Retriever and Merci Retriever, respectively.Disclosure: Dr. Shi has nothing to disclose.

Teaching NeuroImages: Hyperdense posterior cerebral artery sign
A 38-year-old man presented to the emergency department with right-sided weakness, sensory loss, and hemianopsia. CT head showed a left hyperdense posterior cerebral artery sign (HPCAS) (figure 1). CT angiogram of the head confirmed a left posterior cerebral artery (PCA) occlusion (figure 2). MRI demonstrated a left PCA infarct. Transesophageal echocardiogram revealed an atrial septal aneurysm and patent foramen ovale. He was treated with antiplatelet therapy. The HPCAS has been considered a marker for acute ischemia in the PCA territory.1 Recognizing the HPCAS on CT in acute stroke may help in the diagnosis and treatment ...
