BACKGROUND AND PURPOSE: The application of radiopaque markers to the Solitaire™ stent-retriever for better visibility during mechanical thrombectomy (MT) has the potential to alter the well-known characteristics of the device; however, it is uncertain whether this adjustment influences efficacy or safety of the enhanced stent-retriever. METHODS: Retrospective analysis of stroke databases of three comprehensive stroke centers. Our investigation was focused on technical and angiographic parameters, including procedure times, reperfusion results (thrombolysis in cerebral infarction, TICI), periprocedural complications and favorable early neurological recovery at discharge (modified Rankin scale ≤2 or National Institutes of Health Stroke Scale, NIHSS = 0 or ∆NIHSS ≥ 10), from consecutive patients with acute anterior circulation ischemic stroke treated with a Solitaire™ Platinum stent-retriever between October 2016 and March 2017...

INTRODUCTION: Mechanical thrombectomy (MT) is increasingly used for large-vessel occlusions (LVO), but randomized clinical trial (RCT) level data with regard to differences in clinical outcomes of MT devices are limited. We conducted a network meta-analysis (NMA) that enables comparison of modern MT devices (Trevo, Solitaire, Aspiration) and strategies (stent retriever vs aspiration) across trials. METHODS: Relevant RCTs were identified by a systematic review. The efficacy outcome was 90-day functional independence (modified Rankin Scale (mRS) score 0-2)...

RATIONALE: The superior sagittal sinus (SSS) and transverse sinus are the major dural sinuses that receive a considerable amount of venous drainage. The occlusion of them has been suggested to cause intracranial hypertension, hemorrhage, and lead to potentially fatal consequences. PATIENT CONCERNS: We reported a 35-year-old woman with headache presented to our emergency department with a decreased level of consciousness and epileptic seizures. The examination of speech, higher mental function, and cranial nerve were normal...

BACKGROUND AND PURPOSE: The Solitaire FR can be used not only as a tool for mechanical thrombectomy but also as a detachable permanent stent. Our aim was to assess the feasibility and safety of permanent stent placement with the Solitaire FR compared with other self-expanding stents for intracranial artery recanalization for acute ischemic stroke. MATERIALS AND METHODS: From January 2011 through January 2016, we retrospectively selected 2979 patients with acute ischemic stroke...

The solitaire illusion is a numerosity illusion that occurs when the spatial arrangement of items influences quantity estimation. To date, this illusion has been reported in monkeys, although it seems to be weaker compared with its prevalence in humans, and no study has investigated whether nonprimate species perceive it. In the present work, we asked whether a more distantly related species, fish, perceived the solitaire illusion. To achieve this goal, adult guppies (Poecilia reticulata) were trained to select the array containing the larger quantity of black dots in the presence of 2 mixed arrays containing white and black dots...

BACKGROUND AND PURPOSE: Endovascular therapy has become the standard of care for patients with disabling anterior circulation ischemic stroke due to proximal intracranial thrombi. Our aim was to determine whether the beneficial effect of endovascular treatment on functional outcome could be explained by a reduction in posttreatment infarct volume in the Endovascular Revascularization With Solitaire Device Versus Best Medical Therapy in Anterior Circulation Stroke Within 8 Hours (REVASCAT) trial...

We present 2 cases of complicated mechanical thrombectomy involving tandem cervical internal carotid artery and middle cerebral artery occlusion using the Solitaire FR stent and simultaneous carotid stent angioplasty. During the procedures, the Solitaire stents containing the thrombus were wedged into the open-cell carotid stents, which were already deployed for proximal flow restoration. We describe the methods used to avoid and overcome such complications.

Objective: Few studies have reported the outcome of mechanical thrombectomy with Solitaire stent retrival (MTSR) in subtypes of acute ischemic stroke. The purpose of this study was to evaluate the efficacy and result of MTSR in acute cardioembolic stroke. Methods: Twenty consecutive patients with acute cardioembolic stroke were treated by MTSR. The angiographic outcome was assessed by thrombolysis in cerebral infarction (TICI) grade. TICI grade 2a, 2b, or 3 with a measurable thrombus that was retrieved was considered as a success when MTSR was performed in the site of primary vessel occlusion, and TICI grade 2b or 3 was considered as a success when final result was reported...

Microcatheter contrast injection (MCI) prior to stent retriever deployment for the treatment of acute ischemic stroke may be useful for evaluation of distal anatomy and flow patterns beyond the occlusion. However, prior data from intra-arterialthrombolysis suggested that MCI increases the risk of intracranial hemorrhage (ICH). The safety and utility of MCI has not been investigated in the setting of thrombectomy. METHODS: We analyzed the Solitaire With the Intention For Thrombectomy as Primary Endovascular Treatment (SWIFT PRIME) trial to correlate pre-intervention MCI flow with collateral flow, and to investigate its impact on ICH and clinical outcome after thrombectomy with the Solitaire device...

Background: Over the course of the thrombectomy procedure, clot fragments may become dislodged and lead to downstream emboli due to manipulation of an endovascular device. The EmboTrap thrombectomy system features an inner stent channel with an outer stent trap design that may potentially reduce the risk of distal clot fragmentation during clot removal. We tested the hypothesis that distal emboli to both the same and new territory generated during mechanical thrombectomy are a function of device design...

BACKGROUND AND IMPORTANCE: Coil migration is a potential complication of endovascular aneurysm treatment. Dislodged coils into the parent artery require retrieval to prevent thromboembolic complications. A variety of techniques for coil retrieval have been described, including the use of single stentrievers and aspiration catheters. CLINICAL PRESENTATION: The use of 2 stentrievers, as opposed to a single device, was thought to be advantageous in coil removal by the additional point of friction due to the extensive length of coil stretching and earlier failure of a single device...

BACKGROUND: Endovascular treatment for large-vessel acute ischemic stroke (AIS) has rapidly emerged. However, the understanding of the complex biology involving endothelial cells (ECs) remains scarce. METHODS: Using stent retrievers during endovascular thrombectomy (ET) in patients with AIS, ECs were segregated, centrifuged in a dissociation buffer, and suspended in endothelial specific antibody solution. Subsequently, fluorescence-activated cell sorting (FACS) and microscopic analyses were performed...

OBJECTIVE: Acute ischemic stroke (AIS) is an important global health problem. Intravenous (IV) thrombolysis with recombinant tissue plasminogen activator (rt-PA) is the standard treatment. However, only a small number of patients benefit from it because of strict application restrictions. Increasing evidence has demonstrated that mechanical thrombectomy is an effective and safe therapy for AIS. PATIENTS AND METHODS: We present 14 cases of successful recanalization with Solitaire devices for AIS patients after stroke onset...

Paradoxical embolization is the mechanism for patent foramen ovale (PFO)-associated cryptogenic stroke and transcatheter closure of PFO may prevent recurrent ischemic stroke. Mechanical thrombectomy is promising to treat acute ischemic stroke due to high rates of reperfusion and reduced intracranial hemorrhage complications. We report the case of a 27-year-old woman with a massive cerebral infarction but no evidence for any atherosclerosis, who received an urgent mechanical thrombectomy with a Solitaire device...
