Biomechanics of Human Carotid Artery with Pathological Tortuosity
Pathological tortuosity of carotid artery ranks second among the causes of cerebro-vascular insufficiency. In their previous researches
authors have described the influence of pathological tortuosity type on carotid artery behaviour. In this article we discuss the influence
of different anatomic (bending angle, bulb size) and rheological factors on haemodynamics and stress-strain state of carotid artery
with pathological tortuosity. Decreasing of the bending angle leads to blood volume reduction in brain and possible formation of
septal stenosis in bending area. Diminution of hematocrit level promotes the initiation of atherogenesis in internal carotid bend.
Computational modeling of reconstructive surgery of pathologically tortuous carotid of the patient with atherosclerosis was carried
out. Numerical analysis of plausible model of patient carotid before pathology formation was conducted. Volume blood flow after
surgery has increased by 11%, but remained to be lower than in the healthy patient.
