BACKGROUND: The Interventional Management of Stroke III (IMS-III) trial demonstrated no benefit for intravenous recombinant tissue plasminogen activator (IV rt-PA) followed by endovascular therapy versus IV rt-PA alone. However, IMS-III mostly included earlier generation devices. The recent thrombectomy trials have incorporated the stent-retriever technology, but their generalizability remains unknown. METHODS: The North American Solitaire Acute Stroke (NASA) registry recruited patients treated with the Solitaire FR™ device between March 2012 and February 2013...

BACKGROUND AND PURPOSE: Endovascular therapy in addition to standard care (EVT+SC) has been demonstrated to be more effective than SC in acute ischemic large vessel occlusion stroke. Our aim was to determine the cost-effectiveness of EVT+SC depending on patients' initial National Institutes of Health Stroke Scale (NIHSS) score, time from symptom onset, Alberta Stroke Program Early CT Score (ASPECTS), and occlusion location. METHODS: A decision model based on Markov simulations estimated lifetime costs and quality-adjusted life years (QALYs) associated with both strategies applied in a US setting...

Ischaemic stroke is a common cause of death and incapacity and is related in most cases to vascular disease. Intracranial vessel occlusion due to tumour emboli is a rare entity and adequate treatment for this condition is not defined. The use of mechanical thrombectomy devices is considered the treatment of choice for major intracranial vessel occlusion; however, no recommendation can be made in the case of tumour thrombembolia. This report describes two cases who presented with a middle cerebral artery occlusion due to tumour emboli and that were treated using the Solitaire thrombectomy device...

BACKGROUND: The clot burden score (CBS) was developed as a tool to evaluate the extent of intracranial thrombus burden in patients with anterior circulation acute ischemic stroke. CBS is based on the presence or absence of contrast opacification on CT angiography (CTA). Its value in predicting radiographic and clinical outcomes in patients given endovascular stroke therapy remains unknown. OBJECTIVE: To evaluate the relationship between CBS and outcomes after stent retriever thrombectomy in the interventional arm of the SWIFT PRIME trial...

Solitaire FR stent-based mechanical thrombectomy provides clinical benefit in selected patients with acute ischaemic stroke due to large vessel occlusion. A dreaded device complication that is associated with poor technical and clinical outcome is stent detachment. Retrieval of the detached stent can be technically challenging and has been attempted with variable success. The key benefit of this strategy is the lack of need to administer fibrinolytic/antiplatelet agents that can potentially be catastrophic in the setting of acute stroke...

BACKGROUND: It has been amply demonstrated that endovascular procedures can be successful treatment for stroke, both in terms of revascularization and clinical outcome. There is not, however, a published comparison of any histological or ultrastructural damage to the vessels that may be caused by a direct aspiration first pass technique (ADAPT) or stent retrievers (SR) used in these procedures. This study analyses and compares acute damage to the arterial wall caused by ADAPT or SR. MATERIAL AND METHODS: Damage to the walls of swine extracranial arteries was evaluated after ADAPT with the Penumbra system or thrombectomy with an SR (Solitaire 6×30)...

Basilar artery occlusion (BAO) remains one of the most devastating subtypes of ischemic stroke, and prognosis is poor if early recanalization is not achieved. The purpose of this study was to evaluate the safety and technical feasibility of mechanical thrombectomy with the Solitaire AB stent (Covidien, Irvine, CA, USA) for the treatment of acute BAO through a single-center experience. Twenty-one patients with acute BAO were treated with mechanical thrombectomy with the Solitaire AB stent device between 1st September 2011 and 1st December 2014...

OBJECTIVE Contrary to acute ischemic stroke involving the anterior circulation, no randomized trial has yet demonstrated the safety and effectiveness of endovascular management in acute basilar artery occlusion (BAO). Recently developed thrombectomy devices, such as stentrievers and aspiration systems, have helped in improving the endovascular management of acute ischemic stroke. The authors sought to assess the impact of these devices in the endovascular treatment of acute BAO. METHODS A retrospective analysis of 34 consecutive patients treated in Pitié-Salpêtrière Hospital for acute BAO was carried out...

Mechanical thrombectomy using retrievable stents or stent retriever devices has become the mainstay of intra-arterial therapy for acute ischemic stroke. The recent publication of a series of positive trials supporting intra-arterial therapy as standard of care for the treatment of large vessel occlusion will likely further increase stent retriever use. Rarely, premature stent detachment during thrombectomy may be encountered. In our multicenter case series, we found a rate of detachment of less than 1% (n = 7/1,067), and all were first-generation Solitaire FR devices...
