Rescue therapy after failed thrombectomy in medium/distal vessel occlusions: A retrospective analysis of an international, multi-center registry.

Background: There are limited therapeutic options in cases of failed reperfusion (modified thrombolysis in cerebral infarction [mTICI] score < 2b) after stent-retriever and/or aspiration based endovascular treatment (EVT) for acute ischemic stroke. Despite the absence of data supporting its use, rescue therapy (balloon angioplasty and/or stent implantation) is often utilized in such cases. Studies are limited to large vessel occlusions, while the outcomes and complications after rescue therapy in medium/distal vessel occlusions (MDVOs) have not been reported.

Technical and clinical outcomes of thrombectomy in patients with acute medium vessel occlusion and large vessel occlusion; sub-analyses of Japan Trevo registry.

Background: Little is known about endovascular therapy (EVT) for patients with medium vessel occlusion (MeVO) and more work is needed to establish its efficacy and to understand hemorrhagic complications.

Methods: We analyzed the Japan Trevo Registry, which enrolled patients with acute stroke who underwent EVT using Trevo Retriever alone or in combination with an aspiration catheter. The primary outcome was effective reperfusion, and the secondary outcome was modified Rankin scale 0-2 at 90 days.

Impact of atherosclerotic etiology on technical and clinical outcomes of mechanical thrombectomy with a stent retriever: subanalysis of the Japan Trevo Registry.

Background: The safety and effectiveness of stent retriever use for patients with acute large vessel occlusion (LVO) due to intracranial atherosclerotic disease (ICAD) is not well established. We investigated the differences in clinical outcomes in patients with and without ICAD.

Methods: We analyzed the Japan Trevo Registry, a nationwide registry which enrolled patients with acute LVO who underwent endovascular therapy (EVT) using the Trevo retriever alone or in combination with an aspiration catheter.

Characteristics of Calcification and Their Association with Carotid Plaque Vulnerability.

Background: Carotid plaque vulnerability is one of the important features for evaluating the risk of subsequent ischemic stroke. Although magnetic resonance imaging (MRI) is the gold standard modality for evaluating plaque vulnerability, some patients cannot undergo MRI because of physical or economic issues. Computed tomography (CT) is more readily available.

A Patient with Carotid Mobile Plaques Treated by Carotid Artery Stenting Using a Double-layer Micromesh Stent.

Objective: We report a case of carotid mobile plaques treated by carotid artery stenting (CAS) using a double-layer micromesh stent (CASPER stent).

Case Presentation: An 86-year-old male presented with lightheadedness. Carotid artery ultrasound revealed mobile plaques in the right internal carotid artery (ICA).
