endovascular thrombectomy after larg-vessel

Jenq-Lin Yang, Sujira Mukda, Shang-Der Chen
Stroke is the leading cause of adult disability and mortality in most developing and developed countries. The current best practices for patients with acute ischemic stroke include intravenous tissue plasminogen activator and endovascular thrombectomy for large-vessel occlusion to improve clinical outcomes. However, only a limited portion of patients receive thrombolytic therapy or endovascular treatment because the therapeutic time window after ischemic stroke is narrow. To address the current shortage of stroke management approaches, it is critical to identify new potential therapeutic targets...

OBJECTIVE: In this multicenter study, we sought to evaluate comparative safety and efficacy of combined IV thrombolysis (IVT) and mechanical thrombectomy (MT) vs direct MT in emergent large vessel occlusion (ELVO) patients. METHODS: Consecutive ELVO patients treated with MT at 6 high-volume endovascular centers were evaluated. Standard safety and efficacy outcomes (successful reperfusion [modified Thrombolysis in Cerebral Infarction IIb/III], functional independence [FI] [modified Rankin Scale (mRS) score of 0-2 at 3 months], favorable functional outcome [mRS of 0-1 at 3 months], functional improvement [mRS shift by 1-point decrease in mRS score]) were compared between patients who underwent combined IVT and MT vs MT alone...

INTRODUCTION: Mechanical thrombectomy for anterior circulation large vessel occlusion (LVO) improves functional outcome at three months. This therapeutic approach is the new gold standard, with a benefit being also observed in elderly patients. However, data are limited in this heterogeneous and fragile population. The objectives of this study were, first, to describe outcome after mechanical thrombectomy in a representative group of patients over 80. Second, to evaluate factors associated with a favorable functional outcome after thrombectomy for anterior circulation LVO in elderly patients (aged≥ 80 years)...

INTRODUCTION: Endovascular intracranial thrombectomy (IT) has established itself as the standard of care in treating large-vessel anterior circulation acute ischemic stroke (AIS). However, internal carotid artery (ICA) stenosis/occlusion hampers distal access and controversy about simultaneous emergency ICA stenting ensues. The purpose of this review was to evaluate the safety of emergency ICA stenting in combination with IT for AIS with tandem occlusions. To our knowledge this is the first meta-analysis to evaluate emergency ICA stenting in tandem occlusions, combining results from studies with a control group...

Importance: Endovascular therapy (EVT) is the standard of care for select patients who had a stroke caused by a large vessel occlusion in the anterior circulation, but there is uncertainty regarding the optimal anesthetic approach during EVT. Observational studies suggest that general anesthesia (GA) is associated with worse outcomes compared with conscious sedation (CS). Objective: To examine the effect of type of anesthesia during EVT on infarct growth and clinical outcome...

BACKGROUND AND PURPOSE: Middle cerebral artery M2-segment occlusions represent an important subgroup of patients with acute stroke with large-vessel occlusion. The safety of mechanical thrombectomy, especially contact aspiration (CA), in such distal intracranial occlusions is still under debate. We compared reperfusion, adverse events, neurological recovery, and functional outcome of patients with isolated M2 occlusions according to the first-line strategy mechanical thrombectomy devices (CA versus stent retriever [SR])...

Background: Since large-vessel occlusion (LVO)-related acute ischemic strokes (AIS) are associated with more severe deficits, we hypothesize that the endovascular thrombectomy (ET) may disproportionately benefit stroke-related dependence and death. Methods: To delineate LVO-AIS impact, systematic search identified studies measuring dependence or death [modified Rankin Scale (mRS) 3-6] or mortality following ischemic stroke among consecutive patients presenting with both LVO and non-LVO events within 24 h of symptom onset...

Introduction Endovascular treatment for acute ischemic stroke with acute large-vessel occlusion (ALVO) has established benefits, and rapid treatment is vital for mechanical thrombectomy in ALVO. Time from onset of stroke to groin puncture (OTP) is a practical and useful clinical marker, and OTP should be shortened to obtain the maximum benefit of thrombectomy. Objective The aim of the present study was to assess the impact of early treatment of anterior circulation stroke within three hours after symptom onset and to evaluate the role of OTP in determining outcomes after endovascular therapy...

BACKGROUND: Giant intracranial aneurysms (>25 mm) are uncommon. These lesions typically manifest clinically due to mass effect, acute hemorrhage, or thromboembolic events. To minimize the risk of poor clinical outcome, detailed operative planning and a consideration of all neurosurgical and endovascular techniques are essential before proceeding with microsurgical clipping of ruptured giant aneurysms. CASE DESCRIPTION: We describe a case involving a 15-year-old male with a ruptured giant middle cerebral artery aneurysm treated with microsurgical clipping...

BACKGROUND: Endovascular thrombectomy has demonstrated benefit for patients with acute ischemic stroke from proximal large vessel occlusion. However, limited evidence is available from recent randomized trials on the role of thrombectomy for M2 segment occlusions of the middle cerebral artery (MCA). METHODS: We conducted a systematic review and meta-analysis to investigate clinical and radiographic outcomes, rates of hemorrhagic complications, and mortality after M2 occlusion thrombectomy using modern devices, and compared these outcomes against patients with M1 occlusions...

BACKGROUND AND PURPOSE: Randomized controlled trials have shown that mechanical thrombectomy (MT) plus best medical treatment improves outcome in stroke patients with large-vessel occlusion in the anterior circulation. Whether direct MT is equally effective as bridging thrombolysis (intravenous thrombolysis plus MT) in intravenous thrombolysis eligible patients remains unclear. METHODS: We compared clinical and radiological outcomes at 3 months in 249 bridging patients with 111 patients receiving direct MT for large-vessel occlusion anterior circulation stroke from 2 prospective registries (study period Essen: June 2012 to August 2013, Bern February 2009 to August 2014)...

BACKGROUND: Endovascular thrombectomy has become the de facto standard in the treatment of large vessel occlusion. Previously, a correlation between good outcome and the occlusion site, measured by the 'distance to thrombus' (DT)-as the distance from the carotid T to the beginning of the thrombus-after thrombolysis could be shown. In the present study, we analyze the differences between the chances of a good outcome in respect of DT between patients treated endovascularly or intravenously...

Ischemic stroke is a leading cause of disability and death due to brain arterial occlusion and subsequent ischemia. Acute treatment aims to recanalize the occluded artery as soon as possible. Treatment to achieve recanalization of the occluded artery has evolved during the last couple of years. First therapeutic improvement : intra-veinous thrombolysis (IV rt-PA) was the first validated treatment to achieve reduction in ischemic stroke morbi-mortality. However, rt-PA is efficient in the first hours of stroke onset and for small calibers occluded vessels...

INTRODUCTION: Increased blood pressure variability (BPV) is detrimental after acute ischaemic stroke, but the interaction between BPV and neuroimaging factors that directly influence stroke outcome has not been explored. METHODS: We retrospectively reviewed inpatients from 2007 to 2014 with acute anterior circulation ischaemic stroke, CT perfusion and angiography at hospital admission, and a modified Rankin Scale (mRS) 30-365 days after stroke onset. BPV indices included SD, coefficient of variation and successive variation of the systolic blood pressure between 0 and 120 hours after admission...

The standard of care for patients with acute stroke of the anterior circulation and large vessel occlusion is the combined treatment with intravenous rt-PA (recombinant tissue-type plasminogen activator) and endovascular thrombectomy. The therapy is highly effective while reducing functional deficits and long-term disability. International guidelines recommend thrombectomy during the first 6 h after symptom onset, but new evidence supports its use in selected patients within a time window of up to 24 h...

BACKGROUND AND PURPOSE: Finding of white matter hyperintensity (WMH) has been associated with an increased risk of parenchymal hematoma and poor clinical outcomes after mechanical thrombectomy using old-generation endovascular devices. Currently, no data exist with regard to the risk of mechanical thrombectomy using stentriever devices in patients with significant WMH. We hypothesized that WMH volume will not affect the hemorrhagic and clinical outcome in patients with acute ischemic stroke undergoing thrombectomy using new-generation devices...

BACKGROUND AND OBJECTIVES: Benefit from endovascular thrombectomy (EVT) for large-vessel occlusion (LVO) acute ischaemic stroke (AIS) is well demonstrated. Furthermore, emerging evidence supports efficacy in appropriately selected patients treated beyond current recommendations of 6 h. We evaluated clinical outcomes in patients undergoing late EVT at our institution. METHODS: Retrospective review of prospectively collected clinical database on 355 patients who underwent EVT for LVO AIS...

BACKGROUND AND PURPOSE: White matter (WM) is less vulnerable to ischemia than gray matter. In ischemic stroke caused by acute large-vessel occlusion, successful recanalization might therefore sometimes selectively salvage the WM, leading to infarct patterns confined to gray matter. This study examines occurrence, determinants, and clinical significance of such effects. METHODS: Three hundred twenty-two patients with acute middle cerebral artery occlusion subjected to mechanical thrombectomy were included...

BACKGROUND: Evidence on stent retriever-based thrombectomy (SRT) efficacy in elderly patients is controversial. This study aimed to analyze safety and efficacy outcomes in octogenarians submitted to SRT. METHODS: Analysis was based on a prospective observational registry of patients with stroke because of anterior circulation large-vessel occlusion treated with SRT at our center between January 2015 and September 2016. Patients were dichotomized into 2 age groups: ≤80 and >80 years old...
