Fig. 1.
The vessel outline ROI (with each segment marked by a different colour) is created by the programme on the basis of manually placed points (marked in blue)
Fig. 2.
Carotid circumferential strain graphs before the HD session. Each segment of the vessel’s circumference is marked in a different colour, and the dotted graph indicates values for the whole circumference
Fig. 3.
Carotid circumferential strain graphs of the same patient after the HD session. There is a visible decrease in CS values after the HD session
Fig. 4.
Strain describes a change of dimension (deformation) of a body due to the application of stress expressed as a percentage or fraction. In echocardiography, the deformation of the cardiac wall can be measured in all three dimensions – by radial, circumferential, and longitudinal strain. In our case, the circumferential strain was a measure of the deformation of a ROI tangential to the vessel outline, and radial strain would express deformation in the perpendicular direction
Fig. 5.
Correlation between the difference in whole circumference carotid CS and volume of fluid lost during haemodialysis. The fluid volume is measured in litres. The difference in whole circumference carotid CS is a subtraction of circumferential strain before and after haemodialysis (both are measured as percentages)
Fig. 6.
Correlation between the difference in whole circumference carotid CS and volume of fluid lost during haemodialysis divided by the BMI calculated from dry body mass. The fluid volume is measured in litres. The difference in whole circumference carotid CS is a subtraction of circumferential strain before and after haemodialysis (both are measured as percentages)
