To explore the variation of left common carotid artery diameter (LCCAD) in different body positions, and to provide theoretical basis for prevention and treatment of carotid atherosclerosis. 165 volunteers from Anqing Normal University were divided into three age groups by the methods of literature review, experiment and mathematical statistics. Philips color Doppler cv850 color ultrasound was used to test the LCCAD in four different postures: head up tilt, supine position, head down tilt -30° and head down tilt -90°. Results: There were significant differences in the LCCAD in different postures in three age groups: under 25 years old (excluding 25 years old), 25-59 years old, 60 years old and above. The LCCAD increased with age in the remaining 5 groups (young women, young men, middle-aged women, middle-aged men and old men). The LCCAD increased with age in the order of head down up, supine position, head down tilt - 30° and head down tilt -90°. The LCCAD of human body will change greatly with the change of body position, especially in the elderly. With the increase of age, the performance of systemic atherosclerosis in carotid artery is more obvious, and the possibility of a series of diseases is greater. Therefore, no matter the old, middle-aged and young people, we should strengthen the training on the artery to achieve the effect of prevention and treatment of arterial disease. This study reveals the influence of body position change on blood vessel diameter, which has important guiding significance for human body to stimulate blood vessel training through posture change.
