Thrombectomy for Acute Internal Carotid Thrombosis: Five Thrombectomy Devices Compared [PDF]
European Journal of Vascular and Endovascular Surgery, 2004 To test the safety and efficiency of commercially available thrombectomy catheters in clearing simulated internal carotid artery (ICA) thrombosis.Comparative in vitro study.A model of the ICA was filled with human thrombus, the 'circle of Willis' back pressure was set at either 10 or 30 cm of water.

A Steerable and Expandable Magnetic Aspiration Catheter for Enhanced Aspiration Thrombectomy
Advanced Intelligent Systems, EarlyView.This article presents a novel magnetic aspiration catheter (MAC) that can be both actively steered and undergo distal‐end expansion via externally applied magnetic fields. The MAC facilitates precise branch selection and enhances clot engagement by improving endovascular navigation and aspiration efficiency. Phantom experiments validate its feasibility

Clinical characteristics of unknown symptom onset stroke patients with and without diffusion-weighted imaging and fluid-attenuated inversion recovery mismatch [PDF]
, 2017 Background: Diffusion-weighted imaging (DWI) and fluid-attenuated inversion recovery (FLAIR) mismatch was suggested to identify stroke patients with unknown time of symptom onset likely to be within the time window for thrombolysis. Aims: We aimed

Animal Models and Experimental Medicine, EarlyView.Diabetes combined with ischemic stroke (DMIS) exacerbates brain infarct size and neuronal damage compared to nondiabetic ischemic stroke (IS). This study reveals that microRNA‐34a (miR‐34a) plays a key role in DMIS pathogenesis: miR‐34a directly targets and suppresses brain‐derived neurotrophic factor (BDNF) and Sine oculis homeobox 3 (SIX3), promoting

Annals of Neurology, EarlyView.Objective Cerebral ischemic stroke causes neuronal oxygen/energy deprivation, disrupting mitochondrial function including reduced membrane potential and bioenergetics, exacerbating neuronal injury. Mitochondrial defects are, therefore, a central neuropathological node and potential therapeutic target.

Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Carotid free‐floating thrombus (CFFT) is a rare yet severe cause of the ischemic stroke. Early identification and appropriate management are crucial to prevent recurrent embolic events. A 76‐year‐old man experienced sudden left‐sided hemiparesis and dysarthria.

Simulation of a mechanical thrombectomy device based in the use of self-expandable stents for the blood clots extraction [PDF]
, 2011 Recently, we have presented some studies concerning the analysis, design and optimization of one experimental device developed in the UK - GPTAD - which has been designed to remove blood clots without the need to make contact with the clot itself ...
