Oral direct thrombin inhibitor as an alternative in the management of cerebral venous thrombosis: a series of 15 patients
ConclusionsWe report the largest series of cerebral vein thrombosis patients treated with dabigatran. Clinical outcome was excellent in most patients and not different from other studies. Dabigatran could possibly be considered an alternative to warfarin; nevertheless, further prospective assessment with randomized controlled studies is warranted.

Acute Stroke After Carotid Endarterectomy: Time for a Paradigm Shift? Multicenter Experience With Emergent Carotid Artery Stenting With or Without Intracranial Tandem Occlusion Thrombectomy
CONCLUSION: Emergent endovascular evaluation in the setting of acute post--carotid endarterectomy thrombosis is a safe and timely treatment option, with the benefit of detecting and treating embolic intracranial lesions. Immediate angiography and intervention in this rare surgical complication show promising initial results.

Meningovascular Neurosyphilis Presenting as Ischemic Stroke in an HIV Positive Patient (P2.297)
CONCLUSIONS: MVNS should be considered in AIS patients without known risk factors, especially in patients who are HIV positive. Prompt treatment can halt progression of and possibly improve symptomatology. Diagnosis and improvement can be monitored with intracranial arterial wall imaging using contrast-enhanced MRI.Disclosure: Dr. Tipirneni has nothing to disclose.

"Reverse Locked-in Syndrome": A rare presentation after endovascular recanalization of top-of-the-basilar artery occlusion (P4.302)
CONCLUSION: Complete opthalmoplegia, bilateral ptosis, and arreactive mydriasis without appendicular motor dysfunction, a "reverse locked-in" state, is a rare presentation after ischemic stroke involving the paramedian midbrain tegmentum. This syndrome is the opposite of locked-in syndrome, which is cause by ventral pontine infarction. Timely endovascular thrombectomy, even when a patient presents in coma, may offer dramatic recovery with good functional outcome.Disclosure: Dr. Raibagkar has nothing to disclose.

Posterior circulation flow diversion: a single-center experience and literature review
Conclusions Flow diversion may be a possible treatment in carefully selected patients with high-risk atypical posterior circulation aneurysms, with poor natural history and no optimal treatment strategy. Symptomatic and fusiform large aneurysms appear to carry the highest risk. Further studies are necessary to assess the role of flow diversion in the posterior circulation.

E-003 delayed reocclusion of recanalized intracranial arteries after mechanical thrombectomy in acute stroke patients
ConclusionsWe reviewed these patients and found that delayed reocclusion of recanalized vessels were noted within 24 h after first mechanical thrombectomy. The factors contributed to these results are assumed as TICI grade before and after the first mechanical thrombectomy. But, further evaluation of factors such as NIHSS score, underlying disease, laboratory findings and follow-up angiogram are needed. Also, procedural complications as vasospasm, dissection and hemorrhage should be investigated.DisclosuresK. Jang: None. S. Park: None. D. Jang: None. B. Moon: None. Y. Han: None. Y. Park: None.

Shear-Activated Nanoparticle Aggregates Combined With Temporary Endovascular Bypass to Treat Large Vessel Occlusion Basic Sciences
Conclusions— A novel intra-arterial, nanoparticle-based thrombolytic therapy combined with TEB achieves high rates of complete recanalization. Moreover, this approach reduces vascular trauma as compared with stent-retriever thrombectomy.

MR angiography findings in infants with neonatal arterial ischemic stroke in the middle cerebral artery territory: A prospective study using circle of Willis MR angiography
Publication date: Available online 6 May 2016 Source:European Journal of Radiology Author(s): Béatrice Husson, Lucie Hertz-Pannier, Catherine Adamsbaum, Cyrille Renaud, Emilie Presles, Mickael Dinomais, Manoelle Kossorotoff, Pierre Landrieu, Stéphane Chabrier Aim Neonatal arterial ischemic stroke (NAIS) results from a focal disruption of the blood flow in a cerebral artery by a not well understood mechanism. Our objective is to describe the acute MRangiography (MRA) findings in infants with an NAIS in the middle cerebral artery (MCA) territory and correlate them with early parenchymal infarcts and motor outcom...

Massive pulmonary embolism with acute cor pulmonale
A 51-year-old immobilised man, while recovering at stroke rehabilitation, complained of sudden onset chest pain prior to an unconscious collapse. Observations on arrival were heart rate 120 bpm, blood pressure 80/60 mm Hg and oxygen saturations of 90% on 10 L of oxygen. ECG demonstrated new right bundle branch block (RBBB) with classical S1Q3T3 repolarisation abnormality of acute right heart strain (figure 1A). Urgent CT pulmonary angiogram revealed saddle pulmonary embolism with extensive thrombus burden (figure 1B). Transthoracic echocardiogram (TTE) showed acute right ventricular (RV) overload with c...

Hyperacute Carotid Stenting for Acute Ischemic Stroke After Systemic Thrombolysis with IV rt-PA (P1.282)
Conclusions:These 2 cases demonstrate a successful use of hyperacute carotid stenting and antiplatelet load in patients who received systemic thrombolysis with IV rt-PA. Both had excellent outcomes and no complications. This management may be considered in patients with similar clinical and imaging characteristics.Disclosure: Dr. Marulanda-Londoño has nothing to disclose. Dr. DeLeon-Bendetti has nothing to disclose.

Ischemic Stroke: Histological Thrombus Composition and Pre-Interventional CT Attenuation Are Associated with Intervention Time and Rate of Secondary Embolism
Conclusions: Fibrin-rich thrombi with low erythrocyte percentage are significantly associated with longer intervention times. Embolisms in the thrombectomy process occur more often in thrombi with a small fraction of red blood cells and a low CT-density, suggesting a higher fragility of these thrombi.Cerebrovasc Dis 2017;44:344 –350

Ischemic stroke related to spontaneous.
In conclusion, in patients presenting with an ischemic cerebral accident, meticulous cardiac examination must be performed even in young women with no cardiovascular risk factors given that the occurrence of hematoma or coronary dissection may contribute to the formation of mural thrombi in the setting of myocardial infarction. Cardiac MRI seems to be particularly effective in the diagnosis of myocardial infarction complicated by the presence of intracavitary thrombi. PMID: 29096901 [PubMed - as supplied by publisher]
