Abstract

|
|
Purpose: The duplex scan is recommended for initial assessment of carotid artery disease as a non-invasive diagnostic method. However, the guidelines for diagnosis of carotid stenosis are based on Western guidelines. Therefore, we studied the anatomy and hemodynamics of the carotid and vertebral arteries in a healthy Korean population.
Methods: The study was performed with 421 healthy adults, aged 20 to 69 years (219 men, 202 women; mean age of all patients, 44.32±14.33 years). The flow velocities and luminal diameters of the common, external and internal carotid arteries and the vertebral arteries were examined using a duplex scan.
Results: The luminal diameters of the carotid and vertebral arteries increased significantly with increased age, height and weight and were significantly larger in men than in women. The flow velocities of the carotid and vertebral arteries decreased significantly with increased age. The flow velocities of carotid arteries were significantly faster in men than in women. The flow velocities of the carotid and vertebral arteries varied according to height and weight.
Conclusion: Our results from a healthy Korean population might be used as reference values for diagnosis of carotid and vertebral arterial disease in Koreans.
