INTRODUCTION: Previously, endovascular treatment of @entity850 related to @entity4522 ( @entity15975 ) involving arteries measuring less than 2 mm in diameter was limited. To our knowledge, there are no reports in the literature addressing stent placement for treatment of @entity850 in arteries of this size. METHODS: Four @entity1 aged 33 to 80 years (mean 57.5 years) with medically refractory @entity15975 underwent angioplasty and stenting of small (<2 mm) distal intracerebral arteries. Vessel location and length of follow-up were anterior cerebral artery (ACA) A1 segment (5 months), @entity12643 segment (18 months), middle cerebral artery M1 segment (18 months), and posterior cerebral artery P1 segment (8 months) with vessel calibers ranging from 1.2 to 1.8 mm. Clinical and imaging follow-up ranged from 5 to 18 months. RESULTS: All procedures were successfully performed without complications. Follow-up out to 18 months demonstrated one vessel that went on to occlusion while the other stented vessel segments remained patent. One @entity1 died 8 months after stenting, but the death was not related to @entity16 . The remaining @entity1 experienced resolution of the presenting symptomatology and remained asymptomatic throughout follow-up. CONCLUSION: In this small series, stenoses of distal (<2 mm) cerebral arteries were amenable to treatment using new self-expanding stents. We safely and successfully treated four arteries smaller than 2 mm in diameter with newer self-expanding stents. All @entity1 remained clinically asymptomatic. One stent occluded at 5 months and the others remained patent during follow-up. Longer term clinical follow-up is required to determine the durability and viability of this therapy.
