Intracerebral arterial blood pressure in the vasculature distal to large vessel occlusions in patients with ischemic stroke: correlation with clinical and imaging parameters.

Introduction: Mechanical thrombectomy is a highly effective treatment for acute ischemic stroke (AIS) caused by large vessel occlusions (LVO). However, our understanding of the pathophysiology of AIS is still limited, particularly regarding the ischemic microenvironment distal to the occlusion.

Aim: To investigate the relationship between the intracerebral blood pressure (BP) distal to an LVO and clinical and imaging parameters.

Association of perioperative P2Y inhibitor administration with outcomes for tandem occlusion: RESCUE AT-LVO sub-study.

Background: We aimed to clarify the association between intraoperative P2Y inhibitor administration during EVT and clinical outcomes in patients with anterior circulation TO stroke.

Methods: Among consecutive patients with acute ischemic stroke (AIS) enrolled in the Recovery by Endovascular Salvage for Cerebral Ultra-acute Embolic and Atherothrombotic Stroke with Large Vessel Occlusion Registry from 2016 to 2019, those with anterior circulation TOs who underwent EVT were analyzed. These patients were categorized into the following groups: those who received P2Y inhibitors during the perioperative period and those who did not receive P2Y inhibitors.

Effectiveness and Safety of Mechanical Thrombectomy in Large-Vessel-Occlusion Mild Stroke: Insights from the ASSIST Registry.

Background And Purpose: Mechanical thrombectomy (MT) is effective for acute ischemic stroke, yet its indication in mild stroke remains unclear. This study evaluates MT's effectiveness and safety in low NIHSS patients and assesses different MT strategies' impact on procedural success and clinical outcomes.

Materials And Methods: Data from the ASSIST Registry were analyzed, categorizing patients with large vessel occlusion of the anterior circulation into mild (NIHSS≤5) and moderate-severe (NIHSS>5) stroke groups.

Prolonged venous transit is associated with lower odds of excellent recovery after reperfusion in anterior large-vessel occlusion stroke.

Background And Purpose: Acute ischemic stroke due to anterior circulation large-vessel occlusion (AIS-LVO) remains a leading cause of disability despite successful reperfusion therapies. Prolonged venous transit (PVT) has emerged as a potential prognostic imaging biomarker in AIS-LVO. We aimed to investigate whether PVT is associated with a decreased likelihood of excellent functional outcome (modified Rankin Scale [mRS] score of 0-1 at 90 days) after successful reperfusion.

IRIS, a randomised, double-blind, placebo-controlled trial of interleukin-6 receptor inhibition undergoing endovascular treatment in acute anterior circulation ischaemic stroke: study rationale and design.

Rationale: Neuroprotective strategies based on reperfusion therapy hold substantial promise for acute ischaemic stroke (AIS). Preclinical research indicates that tocilizumab, an interleukin-6 receptor antagonist, can attenuate ischaemia-reperfusion damage by exerting anti-inflammatory and neuroprotective effects.

Aim: To determine tocilizumab's efficacy and safety when combined with endovascular thrombectomy (EVT) in patients with acute anterior circulation large vessel occlusion (LVO).

Intensive Blood Pressure Lowering in Acute Stroke with Intracranial Stenosis Post-Thrombectomy: a secondary analysis of the OPTIMAL-BP trial.

Background: Intensive blood pressure (BP) management within 24 hours after successful reperfusion following endovascular thrombectomy (EVT) is associated with worse functional outcomes than conventional BP management in Asian randomized controlled trials. Given the high prevalence of intracranial atherosclerotic stenosis (ICAS) in Asia, ICAS may influence these outcomes.

Aims: We aimed to assess whether ICAS affects the outcomes of intensive BP management after successful EVT.

Prognostic Prediction Model for Endovascular Treatment of Acute Anterior Circulation Ischemic Stroke Based on Rapid Processing of PerfusIon and Diffusion Software.

Objective: To construct a universally applicable nomogram using computed tomography perfusion parameters based on Rapid processing of PerfusIon and Diffusion software for evaluating the prognosis of acute anterior circulation large vessel occlusion treated by endovascular therapy.

Methods: A total of 130 patients were divided into 2 groups: a group with a good prognosis [Rankin Rating Scale (mRS) score ≤2 points] and a group with a poor prognosis (mRS score >2 points). The least absolute shrinkage and selection operator logistic regression method was used to screen the predictive factors, and a nomogram chart prediction model was established.

Mechanical thrombectomy failure in anterior and posterior circulation stroke: current results from a high-volume comprehensive center.

Background: Mechanical thrombectomy (MT) is an established therapy for acute ischemic stroke (AIS), but recanalization is not always achieved. Common reasons are inadequate removal at the thrombus site and difficulties with the access route. In order to identify risk factors for MT failure we conducted a retrospective study on a high-volume comprehensive stroke center.

Long-Term Outcome of Rescue Stenting for Acute Intracranial Atherosclerotic Stenosis Related Large Vessel Occlusion in Anterior Circulation.

Background And Purpose: Rescue stent (RS) is an accepted rescue option after failed mechanical thrombectomy (MT) for acute ischemic stroke due to intracranial atherosclerotic stenosis (ICAS)-related large vessel occlusion (LVO). However, the long-term outcomes (≥ 12 months) of RS have not yet been elucidated.

Materials And Methods: We retrospectively analyzed the data of 154 patients with RS for ICAS-related LVO, which were identified from prospectively maintained multicenter database of RS after MT failure, to assess good outcome (mRS 0-2), mortality, stroke recurrence, symptomatic intracranial hemorrhage (SICH) and stent patency.

Prediction of Symptomatic Intracranial Hemorrhage Before Mechanical Thrombectomy Using Machine Learning in Patients with Anterior Circulation Large Vessel Occlusion.

Background: Symptomatic intracranial hemorrhage (sICH) after mechanical thrombectomy (MT) is associated with worse outcomes. We sought to develop and internally validate a machine learning (ML) model to predict sICH prior to MT in patients with anterior circulation large vessel occlusion.

Methods: Consecutive adults who underwent MT for internal carotid artery/M1/M2 occlusions at a single institution were reviewed.
