Wave intensity analysis: A novel non-invasive method for determining arterial wave transmission [PDF]

open access: yes, 2002
Wave intensity analysis is a novel technique for assessing wavelet transmission in the cardiovascular system. Using this tool, we have developed non-invasive techniques to study wave transmission in both central & peripheral arteries in man.

Use of magnetic resonance angiography to select candidates with recently symptomatic carotid stenosis for surgery: systematic review [PDF]

open access: yes, 2002
Objective To determine if sufficient evidence exists to support the use of magnetic resonance angiography as a means of selecting patients with recently symptomatic high grade carotid stenosis for surgery.

Computational Fluid Dynamic Simulations In a Model of a Carotid Bifurcation Under Steady Flow Conditions [PDF]

open access: yesarXiv, 2020
Strokes are still one of the leading causes for death after heart diseases and cancer in all over the world. Most strokes happen because an artery that carries blood uphill from the heart to the head gets clogged. Most of the time, as with heart attacks, the problem is atherosclerosis, hardening of the arteries, calcified buildup of fatty deposits on ...

Visualizing Carotid Blood Flow Simulations for Stroke Prevention [PDF]

open access: yesarXiv, 2021
In this work, we investigate how concepts from medical flow visualization can be applied to enhance stroke prevention diagnostics. Our focus lies on carotid stenoses, i.e., local narrowings of the major brain-supplying arteries, which are a frequent cause of stroke.

A horse, a horse, my kingdom for a horse. Saddle thrombosis of carotid bifurcation in acute stroke [PDF]

open access: yes, 2012
Background: Saddle thrombosis is less frequently detected in carotid arteries than in peripheral arterial embolism. The clot and the distal vessel patency have to be promptly recognized in these cases, because if the carotid vessel is open distally ...

Label Propagation for 3D Carotid Vessel Wall Segmentation and Atherosclerosis Diagnosis [PDF]

open access: yesarXiv, 2022
Carotid vessel wall segmentation is a crucial yet challenging task in the computer-aided diagnosis of atherosclerosis. Although numerous deep learning models have achieved remarkable success in many medical image segmentation tasks, accurate segmentation of carotid vessel wall on magnetic resonance (MR) images remains challenging, due to limited ...

Angiogenesis-dependent and independent phases of intimal hyperplasia. [PDF]

open access: yes, 2004
BACKGROUND: Neointimal vascular smooth muscle cell (VSMC) proliferation is a primary cause of occlusive vascular disease, including atherosclerosis, restenosis after percutaneous interventions, and bypass graft stenosis. Angiogenesis is implicated in the

Reflex responses from the main pulmonary artery and bifurcation in anaesthetised dogs [PDF]

open access: yes, 2000
This study was undertaken to determine the reflex cardiovascular and respiratory responses to discrete stimulation of pulmonary arterial baroreceptors using a preparation in which secondary modulation of responses from other reflexes was prevented.

Segmentation of carotid vessel wall using U-Net and segmentation average network [PDF]

open access: yesarXiv, 2020
Segmentation of carotid vessel wall is required in vessel wall volume (VWV) and local vessel-wall-plus-plaque thickness (VWT) quantification of the carotid artery. Manual segmentation of the vessel wall is time-consuming and prone to interobserver variability. In this paper, we proposed a convolution neural network to segment the common carotid artery (
