Endovascular structures of the basilar artery as forms of the basilar nonfusion spectrum [PDF]

Scientific Reports
Cerebrovascular diseases are a growing social and clinical problem. The intravascular anatomy of the cerebral circulation remains poorly understood, although an increasing number of endovascular interventions are being conducted.

Long-term clinical significance of the presence of puff-chandelier ruptures detected by non-obstructive aortic angioscopy [PDF]

Scientific Reports
Although studies have reported various patterns of atherosclerotic aortic plaques (AAPs) detected by non-obstructive aortic angioscopy (NOA), the long-term outcomes associated with AAPs such as puff-chandelier rupture atheromatous plaque (PCR), remain ...

Bench Testing Analysis of Perforation Management in the Setting of Bifurcation Coronary Intervention. [PDF]

Catheter Cardiovasc Interv
ABSTRACT Background Management of coronary perforation in bifurcation lesions with covered stents remains challenging. Aims We aimed to describe a proper practice and toolbox for “jailed‐branch” management after covered stent deployment. Methods Using a bench model, we tested various wires with a 120° angulated microcatheter for their ability to ...

Hypothesis on the role of cholesterol crystals in spontaneously ruptured aortic plaques: Potential triggers for inflammation and systemic effects [PDF]

American Heart Journal Plus
Cholesterol crystals (CCs) are a key component of atherosclerotic plaques and play a pivotal role in plaque progression, rupture, and the resulting inflammatory responses.

Angiographic, ultrasonic, and angioscopic assessment of the coronary artery wall and lumen area configuration after directional atherectomy: the mechanism revisited. [PDF]

, 1995
The purpose of the present study was to use the complementary information of angiography, intravascular ultrasound, and intracoronary angioscopy before and after directional atherectomy to characterize the postatherectomy appearance of vessel wall ...

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 ...

Serial Change and Clinical Impact of Irregular Protrusion in Lesions With Chronic Coronary Syndrome. [PDF]

Catheter Cardiovasc Interv
ABSTRACT Background The changes over time and effects on long‐term clinical outcomes beyond 1 year of irregular protrusion (IP) in chronic coronary syndrome (CCS) remains unclear. Aims This study aimed to assess the time‐dependent change and long‐term clinical impact of IP in CCS lesions.

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.
