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.

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

Mobilization of progenitor cells and vessel healing after implantation of SYNERGY in acute coronary syndrome

Scientific Reports, 2021
This study was aimed to compare the vascular healing process of a SYNERGY stent with that of a PROMUS PREMIER stent in patients with acute coronary syndrome (ACS). In 71 patients with ACS, undergoing coronary stent implantation using the SYNERGY stent (n

Acute Myocardial Infarction Caused by Distal Embolization From a Proximal Ruptured Plaque

JACC: Case Reports, 2020
Generally, in acute myocardial infarction, the plaque rupture site is around the occluded site. In this case, coronary angioscopy effectively detected a rupture at a nonstenotic lesion, and the consequent thrombotic occlusion may lead to acute myocardial

Exploiting molecular probes to perform near‐infrared fluorescence‐guided surgery

VIEW, Volume 1, Issue 4, December 2020., 2020
Near‐infrared (NIR) fluorescence imaging can provide real‐time navigation for surgeons to discriminate boundaries between lesions and healthy tissue, which serves as a promising tool to enhance precise diagnosis and accurate excision during surgery. Although a great quantity of fluorescent probes has been employed in clinical trials, the U.S.

Catheter pose-dependent virtual angioscopy images visualized on augmented reality glasses

Current Directions in Biomedical Engineering, 2019
Fluoroscopy and digital subtraction angiography provide guidance in endovascular aortic repair (EVAR) but introduce radiation exposure and require the administration of contrast agent. To overcome these disadvantages, previous studies proposed to display

A cross-sectional study of nailfold capillary changes in psoriasis

Indian Dermatology Online Journal, 2021
Background: Microcirculation in the skin of psoriasis patients significantly differs from unaffected individuals. Vascular changes precede skin lesions and occur even in nonlesional skin.

Angioscopy-assisted Aneurysm Clipping [PDF]

Neurosurgery, 1999
To test the concept that endovascular angioscopy can assist surgical intracranial aneurysm clipping by providing an endoluminal view of the aneurysm-parent vessel complex.A carotid bifurcation aneurysm was surgically created in a dog at the lingual artery origin.
