Randomized Study Comparing First-Line Dual Versus Single-Stent Retriever Technique: TWIN2WIN.

Background: The double-stent retriever (SR) technique has been described as an effective rescue technique when single-SR fails to induce recanalization. We aimed to assess the safety and efficacy of first-line double-SR in patients with stroke undergoing thrombectomy.

Methods: This was a multicenter, randomized, controlled, blinded adjudicated primary outcome study.

Cyclic Aspiration in Mechanical Thrombectomy: Influencing Factors and Experimental Validation.

Background And Purpose: Mechanical thrombectomy is a fundamental intervention for acute ischemic stroke treatment. While conventional techniques are effective, cyclic aspiration (CyA) shows potential for better recanalization rates. We aim to investigate factors affecting CyA and compare them with static aspiration (StA).

Deep learning-based model for difficult transfemoral access prediction compared with human assessment in stroke thrombectomy.

Background: In mechanical thrombectomy (MT), extracranial vascular tortuosity is among the main determinants of procedure duration and success. Currently, no rapid and reliable method exists to identify the anatomical features precluding fast and stable access to the cervical vessels.

Methods: A retrospective sample of 513 patients were included in this study.

Modeling Robotic-Assisted Mechanical Thrombectomy Procedures with the CorPath GRX Robot: The Core-Flow Study.

Background And Purpose: Endovascular robotic devices may enable experienced neurointerventionalists to remotely perform endovascular thrombectomy. This study aimed to assess the feasibility, safety, and efficacy of robot-assisted endovascular thrombectomy compared with manual procedures by operators with varying levels of experience, using a 3D printed neurovascular model.

Materials And Methods: M1 MCA occlusions were simulated in a 3D printed neurovascular model, linked to a CorPath GRX robot in a biplane angiography suite.

Partial (SAVE) versus Complete (Solumbra) Stent Retriever Retraction Technique for Mechanical Thrombectomy: A Randomized In Vitro Study.

Background And Purpose: Mechanical thrombectomy has become a first-line treatment for acute ischemic stroke. Several techniques combining stent retrievers and distal aspiration catheters have been described. We aimed to characterize the efficacy of 2 commonly used techniques according to clot characteristics.

Impact on collateral flow of devices used for endovascular treatment of stroke: an in-vitro flow model.

Background: Collateral blood supply of distal vessels has been linked to clinical outcome, infarct volume and recanalization rates in patients with large vessel occlusion. Our study aimed to explore the effects of catheterization during mechanical thrombectomy in collaterals.

Methods: We quantified the flow diversion effect secondary to arterial occlusions in an in vitro model which was connected in a flow-loop setup with a saline reservoir and a pump supplying pulsatile flow.
