IntraCranial Atherosclerosis Related Large-vessel Occlusion Treated With Urgent Stenting (ICARUS)

Intracranial stenting (+/- balloon dilatation) will be performed. Decisions regarding intracranial stenting are solely made by the treating physician. This means in specific, that the treating physician decides based on his/her judgement or based on local standards (as reported in the literature) on the devices and/or concomitant medications (including infusion/administration of antiplatelet medicine) used for intracranial stenting.

Patients undergo either (a) continued stent retriever or contact aspiration based endovascular treatment manoeuvres, (b) infusion/administration of antiplatelet medication or (c) stop of the procedure depending on local standard treatment approaches.
