Background Calcification has been proven to be a marker of atherosclerosis and is related
to an increased risk of ischemic stroke. Additionally, calcification was reported to be …

Background The frequent occurrence of calcification in intracranial artery stenosis increases
the risk of ischemic stroke. In previous cases, we have observed a possible relationship …

Background Intracranial vertebrobasilar artery stenosis is an important cause of ischemic
stroke. With its high resolution, intravascular optical coherence tomography (OCT) provides …

Background The incidence and predictors for in-stent restenosis (ISR) was not fully
explored. We aim to investigate the incidence and predictors of ISR after stenting at the …

Sir, Tsutsumi et al. reported the clinical and angiographic data on 12 patients receiving stent
deployment for symptomatic ostial vertebral artery (VA) stenosis [1]. The in-stent re-stenosis …

Objective The study was designed to investigate if vascular occlusion in the internal carotid
artery (ICA) or the contralateral vertebral artery (VA) contribute to developing in-stent …

We present a case report of a patient who developed restenosis 5 months after initial stent
placement. computed tomography (CT) angiography revealed a 70% stenosis, while …

In-stent restenosis or occlusion has been frequently reported as a complication after
angioplasty and stenting in vertebral arteries. Reopening chronic in-stent occlusion in …

Objective: To investigate the clinical value of CT perfusion (CTP) imaging in vertebral artery
stenosis stenting, so as to provide the basis for preoperative and postoperative evaluation …

Background and Objectives In-stent restenosis (ISR) remains a challenge for vertebrobasilar
artery stenting (VBAS). We aimed to investigate the incidence and risk factors of ISR …
