The Relationship

Introduction and purpose. Endothelial cells are subjected to biomechanical stress produced by the bloodstream and tunica media of the vessel. Vascular stiffness and endothelial shear stress have cooperative effects on the endothelial structure and function. However, the relationship of shear stress and arterial stiffness is still poorly understood. The purpose of the study was to assess the relationship of endothelial shear rate and both local and regional vascular stiffness in patients at different stages of the development of atherosclerosis. Methods. The study included 60 patients, 33 men and 27 women. The average age of patients was 54.8±11.7 years. Regional arterial stiffness was assessed by measurement of the pulse wave velocity in the arteries of elastic and muscular types. Local stiffness of the carotid arteries was characterized by Peterson elastic modulus, Young's modulus, stiffness index β, the deformation of the common carotid artery. Endothelial shear rate was measured at the site of the common carotid artery. Results. Average values of carotid endothelial shear rate were equal to 433±127 s-1. Reduced endothelial shear rate in the carotid arteries was associated with an increased Peterson modulus (r = -0.289; p = 0.025) and the stiffness index β (r = -0.280; p = 0.037), and moreover - with decreasing vascular distensibility (r = 0.288; p = 0.026) and deformation (r = 0.296; p = 0.024). Assessment of the relationship between endothelial shear rate and regional vascular stiffness showed weak statistically significant negative correlation of shear rate and PWVcf (r = -0.367; p = 0.014). Conclusion. In study subjects endothelial shear rate reduction in the area of the common carotid artery was associated with an increased Peterson modulus, stiffness index β, decreasing deformation of carotid arteries and increase in aortic stiffness.

Objectives: The triticeal cartilage can be misidentified as an atheromatous plaque in the common carotid artery in radiological images. It is very important to correctly define these two structures and distinguish from each other. The aim of this study, therefore, was to investigate the shape, length, width and the anatomical position of the triticeal cartilage to prevent the interpretation of its presence as an atheromaous plaque or any other pathology located in the neck. Methods: This study was performed retrospectively on 200 CT images of adult patients (age≥20 years; 128 males, 72 females). The shape, size and localization of triticeal cartilage were examined and its prevalence was determined. Results: Triticeal cartilage was not present in 63 cases. It was present unilaterally in 42 cases and bilaterally in 95. The cartilage was located at the C4 level most frequently. The triticeal cartilage was identified under 7 types as circle, double circle, oval, hook, ring, triangle and rod. Circle type was the most common. There was a statistically significant difference for the presence of ring type cartilage between males and females (p<0.05). Although the mean cartilage length and width were higher in males than females, this difference was not statistically significant (p>0.05). Conclusion: The presence of the triticeal cartilage should be considered in the diagnosis of atheroma in carotid arteries. In order to distinguish the triticeal cartilage from other surrounding structures, the shape, level and size of the cartilage must be known.
