Impact of Stenosis Degree on Outcomes of Stent Placement versus Medical Treatment Alone for Symptomatic Intracranial Stenosis: A Pooled Individual Patient Data Analysis

Patients with higher degrees of stenosis are more likely to benefit from stent placement. Patients with intracranial artery stenosis exceeding 85% may be the focus of future studies. If innovations in interventional techniques significantly reduce perioperative risk, the critical threshold of 85% as the degree of stenosis might be reconsidered.
