Abstract

Abstract : Anatomical vessel obstacles such as an intracranial stenosis in stroke are challenging and may lead to delayed clot access for thrombectomy. We describe a simple and effective technique to overcome the step-off between the intermediate catheter and an intracranial vessel stenosis during thrombectomy. The patient presented with acute embolic left middle cerebral artery occlusion and a favorable penumbral pattern. Clot access was made challenging by focal stenosis in the ipsilateral cavernous segment. The balloon-assisted tracking technique was effective in traversing the step-off to enable TICI 3 aspiration thrombectomy. This simple and effective technique should be kept in mind during stroke procedures where a proximal stenotic obstacle complicates access to the site of occlusion.
