Association Between Aortic Wall Parameters on Multidetector Computed Tomography and Ruptured Plaques By Nonobstructive General Angioscopy [PDF]

Journal of the American Heart Association
Background Nonobstructive general angioscopy (NOGA) can identify vulnerable plaques in the aortic lumen that serve as potential risk factors for cardiovascular events such as embolism.

Angioscopy-assisted thoracic endovascular aortic repair for chronic type B aortic dissection: Optimizing stent graft coverage and left subclavian artery coil embolization [PDF]

Journal of Vascular Surgery Cases and Innovative Techniques
We report the case of a 69-year-old man with chronic type B aortic dissection and progressive aneurysmal dilatation. Zone 2 thoracic endovascular aortic repair was performed with carotid-subclavian bypass.

A Parametric Study of Flushing Conditions for Improvement of Angioscopy Visibility

Journal of Functional Biomaterials, 2022
During an angioscopy operation, a transparent liquid called dextran is sprayed out from a catheter to flush the blood away from the space between the camera and target. Medical doctors usually inject dextran at a constant flow rate.

Efficacy of Angioscopy for the Detection of Mobile Carotid Artery Lesions [PDF]

Stroke: Vascular and Interventional Neurology, 2023
Case presentation A 78‐year‐old man with a mobile lesion was diagnosed with thrombus using carotid ultrasonography, but the lesion was not completely resolved with dual antiplatelet and anticoagulation therapy. Direct visualization by angioscopy showed a

Thrombus or tumor?

Clinical Case Reports, 2023
Key clinical message Contrast defects in veins are often diagnosed as benign thrombi, but depending on the patient’s background it is necessary to differentiate between tumor thrombi. It is difficult to differentiate between these using contrast‐enhanced

Safety and feasibility of dual antiplatelet therapy termination guided by angioscopic findings 6 months after flow diverter placement [PDF]

Frontiers in Neurology
BackgroundFlow diverters (FDs) are commonly used to treat intracranial aneurysms with wide necks. Dual antiplatelet therapy (DAPT) is essential during the perioperative period to prevent thrombosis; however, it increases the risk of hemorrhagic ...

Optimal Dual Antiplatelet Therapy Duration For Carotid Artery Stenting On the Basis of Angioscopic Findings [PDF]

Stroke: Vascular and Interventional Neurology
Background Dual antiplatelet therapy plays a crucial role in preventing thrombosis in the perioperative period of carotid artery stenting (CAS); however, it has been associated with a risk of hemorrhagic complications. A standard regimen for the duration

Coronary angioscopy [PDF]

Texas Heart Institute journal, 1995
Coronary angioscopy will not replace angiography as the gold standard for imaging atherosclerotic coronary arteries. However, there may well be a clinical niche for a technology that gives accurate information regarding a specific lesion, if that ...

Clarification of embolic source in ischaemic stroke by non-obstructive general angioscopy [PDF]

Open Heart
Background Aortogenic stroke is an important subtype of embolic strokes, yet lacks a diagnostic method for proactive identification. Non-obstructive general angioscopy (NOGA) is a catheter-based technique to observe spontaneously ruptured aortic plaques (
