Impact of post-procedure stenosis on outcomes of patients with severe intracranial stenosis treated with intracranial stent placement

The optimal target post-procedure stenosis after percutaneous angioplasty and stent placement (PTAS) for intracranial stenosis is unknown. We determined the effect of post-procedure stenosis after intracranial PTAS on subsequent clinical events in patients with severe symptomatic intracranial stenosis.
