Comprehensive CT Assessment of Subclavian Artery Tortuosity: Implications for Optimal Radial Access Selection. [PDF]

JACC Adv
Background: Right radial artery access is the most commonly used approach for coronary angiography. Tortuosity of the right subclavian artery (RSA) may complicate catheter navigation.

Four Severity Levels for Grading the Tortuosity of a Retinal Fundus Image

Journal of Imaging, 2022
Hypertensive retinopathy severity classification is proportionally related to tortuosity severity grading. No tortuosity severity scale enables a computer-aided system to classify the tortuosity severity of a retinal image. This work aimed to introduce a

Relation Between Coronary Tortuosity and Vasomotor Dysfunction in Patients Without Obstructed Coronaries?

Frontiers in Cardiovascular Medicine, 2022
Background: A large proportion of patients with angina and no obstructive coronary artery disease (ANOCA) has underlying coronary vasomotor dysfunction (CVDys), which can be diagnosed by a coronary function test (CFT).

Retinal arteriole tortuosity changes over time in a veteran population with diabetes

Diabetes Epidemiology and Management, 2022
Purpose: Arteriole tortuosity is an important sign of retinal disease which is associated with diabetic retinopathy, but it is unclear how arteriole tortuosity changes over time in populations with diabetes. It has been suggested that retinal vasculature

A narrative review of retinal vascular parameters and the applications (Part I): Measuring methods

Brain Circulation, 2023
The retina is often used to evaluate the vascular health status of eyes and the whole body directly and noninvasively in vivo. Retinal vascular parameters included caliber, tortuosity and fractal dimension.

Carotid Dolichoarteriopathy (Elongation) of the Carotid Arteries in Patients with Ischemic Stroke Anamnesis

Biomedicines, 2023
Carotid artery elongation (ECA) is widespread in the asymptomatic population and among people with a history of ischemic stroke (IS). There are different points of view on the ways these changes contribute to brain ischemic damage pathogenesis. Materials

Arterial Tortuosity and Its Correlation with White Matter Hyperintensities in Acute Ischemic Stroke

Neural Plasticity, 2022
Introduction. The association between arterial tortuosity and acute ischemic stroke (AIS) has been reported, but showing inconsistent results. We hypothesized that tortuosity of extra- and intracranial large arteries might be higher in AIS patients ...
