Four patients underwent angioplasty and stenting of medically refractory symptomatic intracranial atherosclerosis with the new Wingspan stent system. In all 4 patients, CT angiography (CTA) showed an abnormality within the stented segment that was suggestive of nonocclusive in-stent thrombus. However, subsequent conventional angiography findings were typical for in-stent restenosis. The CTA imaging features of in-stent restenosis are important to recognize, and the misinterpretation of in-stent restenosis as in-stent thrombus may result in inappropriate management.

Background: Drug-coated balloons present a potentially advantageous therapeutic approach for managing coronary in-stent restenosis (ISR). However, the comparative benefits of paclitaxel-coated balloons (PCBs) over uncoated balloons (UCBs) remain unclear.
Aims: We conducted a systematic review and meta-analysis to evaluate and compare the clinical outcomes of patients treated with PCBs and UCBs.

Vascular stents are frequently used in interventional therapy for atherosclerotic arteries. Interventional treatment with bare metal stents and drug-eluting stents has significantly reduced mortality. Restenosis and late thrombus were also major safety concerns in stent implantation.

Background And Purpose: The quantitative intra-arterial flow dynamics following percutaneous transluminal angioplasty and stenting (PTAS) for severe intracranial artery stenosis have never been investigated. We aimed to evaluate peritherapeutic intracranial artery flow dynamics following PTAS with quantitative magnetic resonance angiography (qMRA) to predict long-term stent patency.
Design: This is a prospective, single-center study.

Coronary artery in-stent restenosis (ISR) is driven by neointimal hyperplasia and neoatherosclerosis in previously placed stents. Drug eluting stents (DES) have been adopted as first line therapy for the initial episode of ISR. However, recurrent ISR has limited durable salvage options.
