Endovascular interventions are increasingly becoming the preferred approach for treating strokes and cerebral artery diseases. These procedures rely on sophisticated angiographical imaging guidance, which encounters challenges because of limited contrast and spatial resolution. Achieving a more precise visualization of the underlying arterial pathology and neurovascular implants is crucial for accurate procedural decision-making.

- * Outcomes showed that 80% of aneurysms treated with SEAL Arc achieved complete occlusion, significantly higher than the 21% for WEB, alongside better neointimal coverage (86% vs. 49%).
- * Histological results indicated that all aneurysms treated with SEAL Arc were completely healed, suggesting the device is a promising option for early aneurysm treatment.
Objectives: We sought to investigate whether a novel, fast-pullback, high-frequency optical coherence tomography (HF-OCT) imaging system enables data acquisition with a reduced amount of contrast agents while retaining the same qualitative and quantitative lesion assessment to conventional OCT.
Background: The increased amount of administered contrast agents is a major concern when performing intracoronary OCT.
Methods: The present study is a single-center, prospective, observational study including 10 patients with stable coronary artery disease.
Background: High-frequency optical coherence tomography (HF-OCT) is an intravascular imaging method that allows for volumetric imaging of flow diverters in vivo.
Objective: To examine the hypothesis that a threshold for both volume and area of communicating malapposition can be predictive of early aneurysm occlusion.
Methods: Fifty-two rabbits underwent elastase aneurysm formation, followed by treatment with a flow diverter.
