Objective: The efficacy and safety of intra-arterial thrombolysis (IAT) as an adjunct to endovascular thrombectomy (EVT) in large vessel occlusion strokes (LVOS) remain uncertain, with recent randomized controlled trials (RCTs) yielding conflicting results. This meta-analysis aimed to assess the impact of IAT following successful EVT in patients with LVOS.
Methods: A comprehensive search was conducted across PubMed, ClinicalTrials.
Background And Objectives: Acute CT perfusion (CTP) or MRI is not widely available or routinely performed across many stroke centers. We aimed to evaluate whether patients with acute basilar artery occlusion (BAO) who are selected by noncontrast CT (NCCT) for endovascular therapy (EVT) have similar outcomes compared with patients who are selected by CTP.
Methods: This was a post hoc analysis of individual patient-level data from the ATTENTION and ATTENTION IA trials.
Background: Intravenous thrombolysis remains a standard treatment for acute ischemic stroke within 4.5 hours after onset. Vascular reocclusion may occur after intravenous thrombolysis and may be preventable with an antiplatelet agent within the first 24 hours after thrombolysis.

Methods: Patient data from the Endovascular Treatment for Acute Basilar Artery Occlusion (ATTENTION) randomized trial were analyzed for those with BAO who received EVT. Intraprocedural BP data were extracted, with collateral status assessed using the Basilar Artery on CT Angiography (BATMAN) score (BATMAN score ≥7 favorable collateral status, <7 unfavorable).
Objective: This study aimed to evaluate the association between computed tomography perfusion (CTP) parameters and outcomes in basilar artery occlusion (BAO), and to select patients with BAO who may benefit from thrombectomy.
Methods: We performed a post-hoc analysis of patients from the ATTENTION trial with available admission CTP data. CTP parameters evaluated included time to maximum (T) >6 s/8 s/10 s, relative cerebral blood flow (rCBF) <20%/30%/34%/38%/50%, Critical Area Perfusion Score (CAPS), and CTP-posterior circulation acute stroke prognosis early computed tomography score (CTP-pc-ASPECTS), pons-midbrain-thalamus (PMT) hypoperfusion.
Background: Distal medium vessel occlusions (MeVOs) account for an estimated 25% to 40% of all acute ischemic strokes. Emerging evidence from non-randomized trials suggest that endovascular thrombectomy (EVT) can achieve high rates of successful reperfusion in MeVO strokes, with a safety profile comparable to EVT for proximal arterial occlusions. These findings underscore the need for a prospective randomized clinical trial to evaluate the safety and efficacy of EVT for MeVO stroke.

Methods And Results: The derivation cohort (n=221) from the ATTENTION (Endovascular Treatment for Acute Basilar Artery Occlusion) study was used. Variables identified by logistic regression were used to develop the Basilar Artery Collateral Simplified Score (BACSS).
Objective: To assess whether intra-arterial tenecteplase administered after successful endovascular recanalisation improves outcomes in patients with acute arterial occlusion of the posterior circulation.
Design: Multicentre randomised controlled trial.
Setting: 31 hospitals in China, 24 January 2023 to 24 August 2023.
Background: Trials of endovascular therapy for basilar artery occlusion, including vertebral occlusion extending into the basilar artery, have shown inconsistent results. We aimed to pool data to estimate safety and efficacy and to explore the benefit across pre-specified subgroups through individual patient data meta-analysis.
Methods: VERITAS was a systematic review and meta-analysis that pooled patient-level data from trials that recruited patients with vertebrobasilar ischaemic stroke who were randomly assigned to treatment with either endovascular therapy or standard medical treatment alone.
Background: Mechanical thrombectomy is the most effective treatment for restoring reperfusion in large vessel occlusion acute ischaemic stroke, even in patients with posterior circulation. However, the strategy for optimal treatment of patients with acute basilar artery occlusion (BAO) in difficult-to-treat cases in which thrombectomy has failed is unknown.
Aims: The purpose of this study was to evaluate the clinical efficacy and safety of rescue intracranial stenting (RIS) in patients with acute BAO treated with thrombectomy.

Autophagy has both protective and pathogenetic effects on injury caused by cerebral ischemia/reperfusion (I/R). Our previous research has indicated that stimulator of interferon genes (STING) could orchestrate microglia polarization following middle cerebral artery occlusion. However, it remains largely unexplored whether STING balances microglial polarization by regulating autophagy in brain I/R injury.

View Article and Find Full Text PDFImportance: In several randomized clinical trials, endovascular thrombectomy led to better functional outcomes than conventional treatment at 90 days poststroke in patients with acute basilar artery occlusion. However, the long-term clinical outcomes of these patients have not been well delineated.
Objective: To evaluate 1-year clinical outcomes in patients with acute basilar artery occlusion following endovascular thrombectomy vs control.
Background And Purpose: This study aimed to investigate the effect of collateral circulation on the outcomes of thrombectomy versus medical management alone in basilar artery occlusion (BAO) patients with varying stroke severities.
Methods: Data from the ATTENTION cohort were used to perform a post-hoc analysis comparing the outcomes of thrombectomy with medical management in BAO patients with varying degrees of collateral circulation and stroke severity. Basilar Artery on Computed Tomography Angiography (BATMAN) scores were used to quantify the collateral circulation, and the effect was estimated through a primary outcome of 90-day functional independence (modified Rankin Scale score, mRS ≤2).
Pyroptosis signifies a significant form of programmed neuronal demise subsequent to ischemic stroke. In our prior investigations, we demonstrated that the Elabela (ELA)-Apelin receptor (APJ) axis alleviated neuronal death by improving collateral circulation and mitigating ferroptosis in a murine model of middle cerebral artery occlusion (MCAO). However, the connection between ELA and neuronal pyroptosis remains further elucidation.

We prospectively recruited acute BAO patients from 48 stroke centers across 22 Chinese provinces in the ATTENTION registry from 2017 to 2021. Hyperglycemia on admission was defined as glucose ≥7.

Background: Recently, a randomized controlled trial showed a beneficial effect of intra-arterial thrombolysis following successful endovascular thrombectomy (EVT) in patients with acute ischemic stroke due to large vessel occlusion in the anterior circulation. Due to differences in response to thrombolytics in occlusion of the posterior circulation, the purpose of ATTENTION IA is to explore the adjunct benefit of intra-arterial thrombolysis after successful recanalization in patients presenting with large and medium vessel occlusion of the posterior circulation.
Methods: ATTENTION-IA is an investigator-initiated, multicenter, prospective, randomized clinical trial with open-label treatment and blinded endpoint assessment (PROBE).
Objective: Stroke is a kind of cerebrovascular disease with high mortality. TMAO has been shown to aggravate stroke outcomes, but its mechanism remains unclear.
Materials And Methods: Mice were fed with 0.

Background: Acute basilar artery occlusion is a disabling and life-threatening condition. The purpose of this study was to evaluate the impact of occluded vessel location on the prognostic outcomes of patients who underwent endovascular treatment for acute basilar artery occlusion.
Methods: Patient data for this study were obtained from the ATTENTION registry.
Background And Purpose: To examine the clinical and safety outcomes after endovascular treatment (EVT) for acute basilar artery occlusion (BAO) with different anesthetic modalities.
Methods: This was a retrospective analysis using data from the Endovascular Treatment for Acute Basilar Artery Occlusion (ATTENTION) registry. Patients were divided into two groups defined by anesthetic modality performed during EVT: general anesthesia (GA) or non-general anesthesia (non-GA).
Background: To investigate the relationship between clinical routine inflammatory markers, including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), mean platelet volume (MPV), white blood cell count (WBC), neutrophils, lymphocytes, and platelets with clinical outcomes in acute basilar artery occlusion (BAO) patients receiving endovascular treatment (EVT).
Methods: We recruited 2134 acute BAO patients from 48 stroke centers across 22 Chinese provinces in the ATTENTION registry from 2017 to 2021. Blood samples were drawn at admission.
