Angiographic tapering sign as a surrogate marker for large vessel occlusion due to intracranial atherosclerotic stenosis and its clinical implication: a retrospective matched case-control study
Conclusions The tapering sign on the initial DSA could be a surrogate marker for ICAS-related occlusion and procedural difficulty. However, its clinical significance remains unclear. (Source: Journal of NeuroInterventional Surgery)

Mechanical thrombectomy in minor stroke due to isolated M2 occlusion: a multicenter retrospective matched analysis
Conclusion Our multicenter retrospective analysis has shown no benefit of eMT in minor stroke patients with isolated M2 occlusion over a more conservative therapeutic approach. Although our results must be viewed with caution, in these patients it appears reasonable to consider BMM as the first option and rMT in the presence of early neurological deterioration.

Clinical value of automated volumetric quantification of early ischemic tissue changes on non-contrast CT
Conclusion AIV is an independent predictor of clinical outcome and presented a non-inferior performance compared with ASPECTS, without clear advantages for prognostic modelling. (Source: Journal of NeuroInterventional Surgery)

Safety and efficacy of drug coated balloon angioplasty for intracranial atherosclerotic disease
Conclusions After treatment with DCB angioplasty, complications were no different from those after standard balloon angioplasty or stenting. This study suggests that DCB angioplasty may be a safe and effective procedure for intracranial arterial stenosis. (Source: Journal of NeuroInterventional Surgery)

Cost-effectiveness of endovascular thrombectomy in acute stroke patients with large ischemic core
Conclusions The results of this study suggest that EVT is cost-effective in AIS patients with a large ischemic core (ASPECTS 3–5), compared with SC alone over the patient’s lifetime. (Source: Journal of NeuroInterventional Surgery)

Effect of the anastomosis between the posterior inferior cerebellar artery and the superior cerebellar artery on outcomes of acute basilar artery occlusion after endovascular treatment
Conclusions The PICA–SCA anastomosis is significantly associated with better functional outcomes in patients with acute BAO after EVT, especially in those with middle BAO. (Source: Journal of NeuroInterventional Surgery)

Response to: Correspondence on "Transradial flow diversion with an aberrant right subclavian artery" by Hanaoka Y et al
We thank Hanaoka Y et al1 for their letter regarding our video2. In their commentary an alternative access technique is described, making use of a left transradial approach. Importantly, with an aberrant right subclavian artery, one would need to use the descending aorta as the anchoring point during shaping of the guide sheath since the right subclavian artery ostium is not found in the typical anatomic location. We too have adopted a ‘radial-first’ approach at our institution in recent years and commend the authors on the description of their technique. This represents yet another useful strategy neurointerve...

Use of the Simmons guiding sheath via left transradial access as a feasible strategy for neurointerventions in patients with an aberrant right subclavian artery
We read with interest the paper ‘Transradial flow diversion with an aberrant right subclavian artery’ by Bram et al.1 The authors presented the case of a patient with an aberrant right subclavian artery (ARSA) who underwent flow diversion for a small left internal carotid artery (ICA) aneurysm via a right transradial access (TRA). Under general anesthesia, a 6F Slender sheath (Terumo, Tokyo, Japan) was introduced via the right TRA, and a Simmons-2 catheter was delivered into the right subclavian artery. Despite attempts to reshape the Simmons-2 curve, the procedure failed because it prolapsed into the descendin...

Transradial flow diversion with an aberrant right subclavian artery
Transradial access for diagnostic and therapeutic neurointerventional procedures has gained popularity due to a decreased incidence of access site complications and improved patient comfort compared with transfemoral access.1–4 An aberrant right subclavian artery is an aortic arch variant characterized by a right subclavian artery that arises directly from the arch as the most distal great vessel. Transradial access with an aberrant right subclavian artery is anatomically challenging due to the predilection of the catheter system to collapse into the descending aorta. In this (video 1), we describe a step-by-step tec...

Antiplatelets and antithrombotics in neurointerventional procedures: Guideline update
Conclusions Although the quality of evidence is lower than for coronary interventions due to a lower number of patients and procedures, neurointerventional antiplatelet and antithrombotic management shares several themes. Prospective and randomized studies are needed to strengthen the data supporting these recommendations. (Source: Journal of NeuroInterventional Surgery)

Impact of high-sensitivity troponin elevation and dynamic changes on 90-day mortality in patients with acute ischemic stroke after mechanical thrombectomy: results from an observational cohort
Conclusions hs-cTnI dynamic changes, dominated by the rising pattern rather than hs-cTnI elevation, were independent factors associated with 90-day mortality in patients with AIS after MT, especially in elderly subjects. (Source: Journal of NeuroInterventional Surgery)
