The Bononiensis Control Parameter: theoretical discussion and clinical effects

摘要

This paper analyzes the structure of the major artery walls, with a special focusing on their viscoelas-tic properties, in order to verify the behavior of artery tissue during physiological functioning. Then the connection of vascular segments with different mechanical properties are investigated, to apply the results to organ transplantation in humans. Indeed, different wall properties can significantly increase the risk of generation of blood turbulent fluxes and involves, in the arterial vessels, the development of complications such as atherosclerosis. Since the mechanical properties of arterial vessel are influenced by age, the effects of age difference greater than 15 years between donor and recipient is discussed for the case of renal transplant. Results show that differences in mechanical properties of vessels are significantly bound to probability of developing arterial stenosis after renal transplantation.
