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 ...

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 ...

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

Embolic Stroke Caused by Aortic Ruptured Plaque and Thrombus Visualized by Angioscopy

JACC: Case Reports, 2020
Aortogenic embolization is among the major mechanisms of cryptogenic stroke. Angioscopic surveillance of the aortic wall clearly visualized the existence of thrombi and spontaneously ruptured plaques, which dynamically liberated embolic materials. (Level

In vivo coronary angioscopy

Journal of the American College of Cardiology, 1983
The feasibility of in vivo coronary angioscopy was tested utilizing a 1.8 mm angioscope in vessels where blood had been replaced by optically clear liquids, including a new perfluorocarbon emulsion.

Calcified Nodules in the Superficial Femoral Artery Confirmed by Intravascular Ultrasound, Angioscopy, and Histology

JACC: Case Reports, 2020
An 84-year-old man was admitted to the authors’ hospital for the treatment of intermittent claudication. Angiography revealed an exophytic calcified nodules in the distal superficial femoral artery.

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 (
