Background and Purpose— We try to evaluate whether plaque features and perforator stroke after intracranial stenting is associated with the arterial remodeling patterns in patients with severe basilar artery stenosis. Methods— We studied patients with symptomatic intracranial arterial stenosis who underwent high-resolution magnetic resonance imaging from September 2014 to January 2017. Among them, patients with basilar artery stenosis underwent angioplasty and stenting were recruited. Arterial… Expand

Comparison of safety and mid-term effects between direct stenting and angioplasty before stenting in the basilar artery
Angioplasty before stenting is a good way for BA stenting, it makes the operations on difficult lesions as safe as normal one and more optimized stents and safer interventional approach need to be further explored and verified. Expand
Different risk factors in identical features of intracranial atherosclerosis plaques in the posterior and anterior circulation in high-resolution MRI
More risk factors are demonstrated in the posterior than in the anterior circulation in patients with the same ICAP-vulnerable features, highlighting the need for stratification of risk factors in symptomatic ICAPs. Expand


Thirty-Day Outcome of a Multicenter Registry Study of Stenting for Symptomatic Intracranial Artery Stenosis in China
The short-term safety and efficacy of endovascular stenting for patients with severe symptomatic intracranial atherosclerotic stenosis in China is acceptable, and balloon-mounted stent may have lower degree of residual stenosis than self-expanding stent. Expand
Patterns and Implications of Intracranial Arterial Remodeling in Stroke Patients
Intracranial arteries remodel in response to plaque formation, and posterior circulation arteries have a greater capacity for positive remodeling and, consequently, may more likely elude angiographic detection. Expand

Detailed Analysis of Periprocedural Strokes in Patients Undergoing Intracranial Stenting in Stenting and Aggressive Medical Management for Preventing Recurrent Stroke in Intracranial Stenosis (SAMMPRIS)
Periprocedural strokes in SAMMPRIS had multiple causes with the most common being perforator occlusion, and excluding patients with these features from undergoing percutaneous transluminal angioplasty and stenting to lower the procedural risk would limit per cutaneous translumsinal angio-stenting and stent selection to a small subset of patients.

Arterial remodeling of advanced basilar atherosclerosis
3-T high-resolution PDW imaging is a reproducible tool for measuring BA dimensions, and in patients with advanced BA atherosclerosis, PR lesions are more frequently observed and contain larger plaques than non-PR lesions. Expand
Arterial Remodeling: Mechanisms and Clinical Implications
Widespread interest in this phenomenon was stimulated by observations that radial enlargement of vessels (outward remodeling) can compensate for progressive growth of atherosclerotic plaques, thus postponing the development of flow-limiting stenosis. Expand
