Morphological characteristics associated with ruptured intracranial vertebral artery dissecting aneurysms
Conclusion The coexistence of significant proximal and distal stenosis and PICA involvement were independently associated with IVADA rupture. These morphological characteristics may facilitate the assessment of rupture risk in patients with IVADAs.

Endovascular thrombectomy for anterior circulation stroke beyond 6 hours of onset in Sweden 2015 to 2020: rates and outcomes in a nationwide register-based study
Conclusion Late window EVTs have increased substantially over time, and currently account for one third of anterior circulation treatments. Early and late window patients had similar outcomes.

Association between time to treatment and clinical outcomes in endovascular thrombectomy beyond 6 hours without advanced imaging selection
Conclusion In this real-world study, there was minimal change in functional disability, sICH and in-hospital mortality within and across the late window. While confirmatory randomized trials are needed, these findings suggest that EVT remains feasible and safe when performed in AIS patients selected without advanced neuroimaging between 6–24 hours from stroke onset.

Endovascular treatment of acute ischemic stroke in patients with pre-morbid disability: a meta-analysis
Conclusion In eligible patients with pre-morbid disability, observational studies suggest that EVT carries a higher chance of return to baseline mRS compared with patients treated with MM or without pre-morbid disability, although with higher mortality than patients without pre-morbid disability. These findings argue against the routine exclusion of such patients from EVT and merit validation with randomized trials.

Effects of endovascular therapy for mild stroke due to proximal or M2 occlusions: meta-analysis
Conclusions For patients with mild AIS, observational data suggest that EVT may be beneficial for proximal ICA or M1 but not for distal M2 occlusions. Randomized trials are needed to confirm these findings. PROSPERO registration number CRD42021281034.

Endovascular treatment for isolated posterior cerebral artery occlusion stroke in the MR CLEAN registry
Conclusions EVT should be considered in selected patients with AIS with an isolated PCA occlusion, presenting with moderate–severe neurological deficits, as EVT was technically feasible in most of our patients and about half had good clinical outcome. In case of lower NIHSS score, a more conservative approach seems warranted, since periprocedural complications are not uncommon. Nonetheless, EVT seems reasonably safe considering the absence of sICH in our study.

Evaluation of time-resolved whole brain flat panel detector perfusion imaging using RAPID ANGIO in patients with acute stroke: comparison with CT perfusion imaging
Conclusions In our multicenter study, time-resolved whole brain FD-CTP was technically feasible, and qualitative and quantitative perfusion results correlated with those obtained with conventional CTP.

Endovascular therapy may not be beneficial for patients with mild acute ischemic stroke compared to best medical management
We read with great interest the meta-analysis by Lin et al on the comparison of the clinical effectiveness between endovascular therapy (EVT) and best medical management (BMM) in patients with mild acute ischemic stroke (AIS).1 The study is of profound academic importance, and there are some points that we would like to address. In the "Statistical analyses" section, the authors described how they pooled data across studies by using the fixed effects model based on an inverse variance method. Subsequently, in the "Results – Primary outcome" section, the authors stated that for AIS patients with National Institutes of...

Correspondence on "Unplanned readmission after carotid stenting versus endarterectomy: analysis of the United States Nationwide Readmissions Database" by Nazari et al
We read the article by Nazari et al1 comparing carotid endarterectomy and carotid artery stenting. Most of the patients in the article were asymptomatic patients. Asymptomatic carotid stenosis is considered one of the most significant causes of ischemic stroke. The management of asymptomatic carotid stenosis ranges from open surgical approaches to minimally invasive endovascular interventions and medical therapeutics.2 With the advances in the neurosurgical field within the last decade, various surgical interventions have emerged. However, to date, the evidence regarding the optimal interventional strategies for asymptomat...

Stroke thrombectomy volume, rather than stroke center accreditation status of hospitals, is associated with mortality and discharge disposition
Conclusion A higher volume of ST cases was associated with lower mortality and higher home discharge rate. No significant differences in mortality and discharge disposition were found between accredited and non-accredited hospitals.

Risk factors of unexplained early neurological deterioration after treatment for ischemic stroke due to large vessel occlusion: a post hoc analysis of the HERMES study
Conclusions UnEND is not an uncommon event, with a similar rate which ever treatment arm is considered. In the clinical scenario of AIS due to large vessel occlusion, no patient-related factor seems to increase the risk for UnEND when treated by EVT compared with MM.

Endovascular thrombectomy beyond 24 hours from ischemic stroke onset: a propensity score matched cohort study
Conclusion In this real world study, EVT beyond 24 hours from stroke onset or last known well appeared to be feasible, with comparable safety and functional outcomes to EVT initiation between 6 and 24 hours. Randomized trials assessing the efficacy of EVT in the VL window are warranted, but may only be feasible with a large international collaborative approach.

Prospective study on embolization of intracranial aneurysms with the pipeline device (PREMIER study): 3-year results with the application of a flow diverter specific occlusion classification
Conclusions The PED device presents as a safe and effective modality in treating small- and medium-sized intracranial aneurysms. The application of a flow diverter specific occlusion classification attested the long-term durability with higher rate of successful aneurysm occlusion and no documented aneurysm rupture. Trial registration NCT02186561.
