Carotid artery disease and glaucoma. [PDF]
British Journal of Ophthalmology, 1978 Five patients with evidence of severe bilateral carotid artery disease and increased intraocular pressure have been followed up for 3 to 12 years without the development of glaucomatous disc or field changes. Although it is frequently stated that glaucoma patients with low systemic or ophthalmic artery blood pressures show rapid progression of their ...

Surface Metrology of Cerebral Arteries Luminal Surface [PDF]
arXiv, 2023 Atherosclerotic lesions within carotid and cerebral vessels are likely to influence hemodynamics and manifest into vascular pathologies, including Alzheimers Disease and ischemic stroke. Hemodynamics are influenced by changes in luminal diameter of vessels and wall shear stress derived from turbulence, which directly relates to the surface topography ...

Mechanical identification of layer-specific properties of mouse carotid arteries using 3D-DIC and a hyperelastic anisotropic constitutive model [PDF]
Computer Methods in Biomechanics and Biomedical Engineering 15, 1
(2012) 37-48, 2012 The role of mechanics is known to be of primary order in many arterial diseases; however, determining mechanical properties of arteries remains a challenge. This paper discusses the identifiability of the passive mechanical properties of a mouse carotid artery, taking into account the orientation of collagen fibres in the medial and adventitial layers.

Adjusting for bias introduced by instrumental variable estimation in the Cox Proportional Hazards Model [PDF]
Biostatistics, 2017, 2017 Instrumental variable (IV) methods are widely used for estimating average treatment effects in the presence of unmeasured confounders. However, the capability of existing IV procedures, and most notably the two-stage residual inclusion (2SRI) procedure recommended for use in nonlinear contexts, to account for unmeasured confounders in the Cox ...

Motion Magnification in Robotic Sonography: Enabling Pulsation-Aware Artery Segmentation [PDF]
arXiv, 2023 Ultrasound (US) imaging is widely used for diagnosing and monitoring arterial diseases, mainly due to the advantages of being non-invasive, radiation-free, and real-time. In order to provide additional information to assist clinicians in diagnosis, the tubular structures are often segmented from US images.

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

Dynamic Block Matching to assess the longitudinal component of the dense motion field of the carotid artery wall in B-mode ultrasound sequences -- Association with coronary artery disease [PDF]
, 2018 Purpose: The motion of the common carotid artery tissue layers along the vessel axis during the cardiac cycle, observed in ultrasound imaging, is associated with the presence of established cardiovascular risk factors. However, the vast majority of the methods are based on the tracking of a single point, thus failing to capture the overall motion of ...

Continuous and Noninvasive Measurement of Arterial Pulse Pressure and Pressure Waveform using an Image-free Ultrasound System [PDF]
arXiv, 2023 The local beat-to-beat local pulse pressure (PP) and blood pressure waveform of arteries, especially central arteries, are important indicators of the course of cardiovascular diseases (CVDs). Nevertheless, noninvasive measurement of them remains a challenge in the clinic.

3-D Registration on Carotid Artery imaging data: MRI for different timesteps [PDF]
2016 38th Annual International Conference of the IEEE Engineering
in Medicine and Biology Society (EMBC), 2016 A common problem which is faced by the researchers when dealing with arterial carotid imaging data is the registration of the geometrical structures between different imaging modalities or different timesteps. The use of the "Patient Position" DICOM field is not adequate to achieve accurate results due to the fact that the carotid artery is a ...

Carotid artery pseudoaneurysm in Behcet's disease [PDF]
European Journal of Cardio-Thoracic Surgery, 2001 We report a case of carotid artery pseudoaneurysm occurring in a patient with Behcet's disease for the purpose of discussing approach to this unusual complication of Behcet's disease.
