Mechanical properties of the canine internal carotid artery under constant load regimes

1. A method was developed for the study of the mechanical properties of narrow blood vessels under intravascular pressure and axial stretching. 2. A real difference in the deformative properties of the individual segments of the canine internal carotid artery was found experimentally. 3. It follows from the analysis of the experimental data that, under identical tension levels within the normal physiological range, the mechanical properties in the circumferential direction are similar in all the arterial segments. 4. It was found that 30% more energy is required to deform the flexure of the canine internal carotid artery under its topographical and anatomic conditions than that required for the cervical, intraosseous, and intracranial segments of this artery.
