Clinical and Angiographic Outcomes with the Combined Local Aspiration and Retriever in the North American Solitaire Stent-Retriever Acute Stroke (NASA) Registry
Background: Various techniques are used to enhance the results of mechanical thrombectomy with stent-retrievers, including proximal arrest with balloon guide catheter (BGC), conventional large bore proximal catheter (CGC), or in combination with local aspiration through a large-bore catheter positioned at the clot interface (Aspiration-Retriever Technique for Stroke [ARTS]). We evaluated the impact of ARTS in the North American Solitaire Acute Stroke (NASA) registry.Summary: Data on the use of the aspiration technique were available for 285 anterior circulation patients, of which 29 underwent ARTS technique, 131 CGC, and 1...

Moderate to Severe Anemia Is Associated with Poor Functional Outcome in Acute Stroke Patients Treated with Mechanical Thrombectomy
Background: Anemia will negatively affect cerebral collaterals and penumbra. Eventually, it may cause worse clinical outcomes and even increase mortality rates in stroke patients. Anemia has recently been suggested to be an independent risk factor for ischemic stroke. Therefore, we aimed to investigate the effects of the presence of anemia on clinical outcomes in ischemic stroke patients undergoing mechanical thrombectomy.Methods: This was a retrospective study involving the prospectively and consecutively collected data of 90 adult patients between January 2015 and August 2016. Hemoglobin (Hb) cutoff levels were accepted ...

Permanent Deployment of the Solitaire FR ™ Device in the Basilar Artery in an Acute Stroke Scenario
We present 2 cases where the Solitaire device was electrolytically detached to re-establish flow in an occluded or stenotic basilar artery in acutely symptomatic patients. In both cases, a 4 × 15 mm Solitaire device was positioned across the stenotic or occluded portion of the basilar artery and electrolytically detached to maintain vessel patency. Both cases had good clinical outcomes with a National Institutes of Health Stroke Scale (NIHSS) score of 1 (from 24) on 90-day follow-up an d an NIHSS score of 2 (from 7) on 30-day follow-up.Key Messages: Permanent deployment of the Solitaire device may potentially be a safe an...

Novel Distal Emboli Protection Technology: The EmboTrap
Conclusion: The risk of distal embolization can be altered with improved stent retriever design. When encountering fragment-prone clots, EmboTrap thrombectomy may lower the risk of distal embolization.Intervent Neurol 2017;6:268-276 (Source: Interventional Neurology)

Hybrid Retrograde-Antegrade Recanalization of Acute Basilar Artery Occlusion
We describe a case in whom the BA was accessed and recanalized through a retrograde-antegrade approach from the anterior circulation using a large posterior communicating artery (PCOM). Once the BA had been crossed retrogradely through the PCOM, another microcatheter was advanced antegradely through the VA into the BA and right posterior cerebral artery using the “buddy-wire” technique. In this way the BA was recanalized and reconstructed with stents. This technical note demonstrates a new approach to BA treatment when the antegrade access is hampered by advanced VA/BA disease or dissection.Intervent Neurol 2017;6:263-...

Multimodal Therapy for Non-Superacute Vertebral Basilar Artery Occlusion
Conclusion: For patients with posterior circulation stroke due to basilar artery or vertebral artery occlusion who present to the hospital 6 h after symptom onset and who exhibit deterioration of symptoms after drug treatment, multimodal recanalization of the occluded artery may be a feasible and safe therapy.Intervent Neurol 2017;6:254-262 (Source: Interventional Neurology)

Mechanical Thrombectomy for Middle Cerebral Artery Division Occlusions: A Systematic Review and Meta-Analysis
Conclusions: MT of M2 MCA occlusions is as safe as that of main trunk MCA occlusions, and comparable in terms of clinical outcomes and hemorrhagic complications. Randomized clinical trials are needed to assess the impact of MT in patients with M2 occlusions, given that M1 MCA occlusions have different natural histories than M2 occlusions.Intervent Neurol 2017;6:242-253 (Source: Interventional Neurology)

Trends in Endovascular Treatment of Aneurysmal Subarachnoid Hemorrhages
Introduction: Aneurysmal subarachnoid hemorrhage (aSAH) accounts for 5% of all strokes; 30-day mortality is as high as 40%. We sought to evaluate outcomes of aSAH patients treated 2004-2014 by endovascular therapy (EVT), to demonstrate associated trends, and to evaluate angioplasty use for aSAH-related cerebral vasospasm.Methods: The Nationwide Inpatient Sample (NIS) database 2004-2014 was used to derive a study cohort using ICD-9 codes. Survey procedures were used to adjust for stratified cluster design of NIS. NIS trend weights were used to generate national estimates. Mortality during hospitalization and use of angiopla...
