IntroductionDrug‐eluting stent (DES) use in symptomatic intracranial atherosclerosis disease (ICAD) has been described in the literature using different guiding and distal access catheters. Decision was made to deploy a drug eluting stent into the stenosed M1 segment. No tPA was given low NIHSS and resolution of symptoms.
