Delayed Endovascular Thrombectomy in a Patient Suffering from Stroke in Progression after Intravenous Thrombolytic Therapy.
CONCLUSION: In LAO patients, directly proceeding EVT following IVT may not be hesitated. In addition, while LAO patients with incomplete IV-tPA treatment responses result in transient improvement of neurological symptoms but later reversed, EVT may be a potential rescue therapy in carefully selected patients.

Cerebral Arterial Stiffness as A New Marker of Early Stage Atherosclerosis of The Cerebral Large Artery in Acute Stroke.
CONCLUSIONS: Cerebral arterial stiffness has the potential to be a new marker of early stage atherosclerosis of the cerebral large artery. This finding may help us prevent the occurrence of stroke and decrease the burden of society from stroke patients. PMID: 30662019 [PubMed - as supplied by publisher]

E-005 Preliminary results of the SUMMIT NZ ischemic stroke trial: MonoPoint(R) embolectomy featuring a novel 088 aspiration catheter and specialized delivery catheter
ConclusionsPreliminary findings suggest that first-line aspiration embolectomy using a novel MonoPoint® system including an 0.088" inner diameter aspiration catheter achieves a high rate of arterial revascularization with an acceptable safety profile. A full report on enrollment and results are to be presented.Disclosures S. Brew: 1; C; Route 92 Medical. 2; C; Route 92 Medical, Microvention. B.

Improving Prediction of Recanalization in Acute Large Vessel Occlusive Stroke.
CONCLUSIONS: Acute endovascular treatment is the single most important factor promoting recanalization in acute ischemic stroke. Presence of extracranial vessel stenosis or occlusion decreases recanalization rates. In patients with intracranial occlusions, higher NIHSS and ASPECTS and normal vigilance facilitate recanalization. Integration in treatment algorithms could influence recanalization strategies in individual patients. This article is protected by copyright. All rights reserved.

Isolated Cortical Vein Thrombosis Associated with Prothrombin Gene Mutation
We report a 47-year-old female patient who had a frontal hemorrhage with headache associated with contralateral hemiparesis and hemisensory deficit on presentation. This hemorrhagic stroke was localized in a nonarterial territory, and it was caused by ipsilateral and isolated thrombosis of the vein of Labbe found on catheter angiogram that demonstrated a filling defect of the vein of Labbe at its connection with the transverse sinus. There were no filling defects in the superficial middle cerebral veins. Our patient had a family history of cardiovascular disease, stroke, and factor V Leiden mutation and cigarette smoking a...

Venous Flow Stagnation in Acute Ischemic Stroke Patients Undergoing Endovascular Treatment (P4.237)

Timing of recanalization and outcome in ischemic-stroke patients treated with recombinant tissue plasminogen activator.
CONCLUSION: These data suggest that DR is associated with clinical deterioration. Patients treated with rtPA thrombolysis should be under close observation for 6-24 h. Corresponding treatment should be considered once DR appears. PMID: 25182802 [PubMed - as supplied by publisher]

Complex interventional treatment in a patient with atrial fibrillation and stroke caused by large carotid artery thrombus: a case report
Conclusion: Emergency carotid embolectomy together with thrombectomy and local thrombolytic rt-PA treatment may be a reasonable rescue therapy for carefully selected patients with large-vessel acute stroke. Further research is needed to establish the advantages and safety of surgical thrombectomy in patients with acute embolic occlusion of the carotid artery and ineffectiveness of or contraindications for systemic thrombolytic treatment.

Comparison of susceptibility-weighted and perfusion-weighted magnetic resonance imaging in the detection of penumbra in acute ischemic stroke
Conclusions DWI-SWI mismatch is a good marker for evaluating ischemic penumbra in stroke patients with cerebral infarction. SWI can detect thrombus in the affected vessels, and may be useful for guiding intra-arterial thrombolytic therapy.

Thrombus Characteristics Are Related to Collaterals and Angioarchitecture in Acute Stroke.
CONCLUSIONS: Clot length and baseline collateral status are independent predictors of clot hyperdensity on NCCT and blooming artifact on gradient recall echo. Longer clots are more likely to be hyperdense and to bloom more, probably because portions of these clots are freshly formed locally due to of stasis of blood around the original clot. This stasis could be because of poor collaterals and inefficient angio-architecture within the cerebral arterial tree. PMID: 26365832 [PubMed - as supplied by publisher]

Endovascular Treatment of Acute Ischemic Stroke Due to Tandem Occlusions: Large Multicenter Series and Systematic Review
Conclusions: Acute endovascular treatment of tandem anterior circulation occlusions yields good outcomes and has similar outcome predictors to isolated intracranial occlusions. Given their comparable clinical behavior, these patients should be included in future trials.Cerebrovasc Dis 2016;41:306-312

Midbrain and bilateral paramedian thalamic stroke due to artery of Percheron occlusion.
CONCLUSION: Bilateral thalamic stroke due to artery of Percheron occlusion is a rare presentation of stroke, which can be overlooked in routine CT scan. If diagnosed, it requires further evaluation for stroke risk factors, especially cardiovascular disorders associated with increased embolic risk. PMID: 27154444 [PubMed - as supplied by publisher]

Etiologies of internal carotid artery pseudo-occlusions in acute stroke patients: what neurointerventionalists can expect.
Abstract In cases of acute stroke, differentiation between an occluded and a patent internal carotid artery (ICA) is crucial for diagnosis and management. Although computed tomography angiography (CTA) can be highly accurate in defining high-grade stenosis and ICA occlusions, misleading ICA occlusion patterns are not rare in acute stroke patients. We investigated the underlying causes of ICA pseudo-occlusions with CTA with respect to digital subtraction angiography (DSA). 11 out of 72 patients had pseudo-occlusion on CTA. Of these, there were three cases of tandem occlusions accompanying high-grade ICA stenosis, f...
