Intracoronary Thrombogenicity in Patients with Vasospastic Angina: An Observation Using Coronary Angioscopy

Diagnostics, 2021
Background: Despite significant interest in intracoronary thrombi in patients with vasospastic angina (VSA), the phenomenon remains unclarified. Therefore, we investigated a possible relationship using coronary angioscopy (CAS) in VSA patients.

Immediate Angioscopic Investigation After Cerebral Artery Thrombectomy Revealed Aortogenic Cerebral Infarction

Stroke: Vascular and Interventional Neurology, 2023
Background Aortogenic embolism is one of the causes of embolic stroke of undetermined source, which can be difficult to diagnose. Methods We present the case of a 74‐year‐old male patient with a history of Bentall surgery and thoracic endovascular aortic

Efficacy of non-obstructive aortic angioscopy for detecting a thoracic aortic graft rupture: a case report

Surgical Case Reports, 2022
Background Non-anastomotic thoracic aortic graft rupture is extremely rare and difficult to diagnose. Non-obstructive general angioscopy can help monitor the aortic intima and detect the locations of abnormal findings, while aortic angioscopy can detect ...

False lumen thrombus following aortic dissection diagnosed as the source of repeat lower extremity emboli with angioscopy: a case report

Surgical Case Reports, 2022
Background Acute arterial embolization caused by a free-floating thrombus of the false lumen after surgery for acute aortic dissection is a rare complication; hence, determining its cause may be difficult.

Is a thin diameter ureteroscope feasible for image guided intravascular procedures?

Current Directions in Biomedical Engineering, 2020
Vascular endoscopic imaging is known for a long time but has never made its way into clinical routine. Reasons for that are the complexity, lack of low-cost portable systems, and the lack of suitable endoscopes providing high image quality with small ...

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
