Abstract

This study evaluated the relationship between spontaneous echo contrast (SEC) in the internal jugular vein (JV), atherosclerotic markers and ischemic stroke. One hundred twenty patients with acute ischemic stroke and 120 controls were recruited. SEC score correlated with plasma level of fibrinogen (coefficient: 0.105, p=0.022), hemoglobin (coefficient: 0.122, p=0.008) and presence of JV reflux (coefficient: 0.314, p<0.001) and peak flow velocity (coefficient: -0.244, p<0.001) in the corresponding JV, but did not correlate with carotid plaque score (coefficient: 0.042, p=0.358) or intima-media thickness (coefficient: 0.067, p=0.303). Multivariate regression analysis revealed that fibrinogen level, SEC score, intima-media thickness, plaque score and history of coronary artery disease were associated with acute ischemic stroke. In conclusion, the severity of SEC in the JV might represent the tendency toward thrombogenesis in diseased cerebral circulation possibly through mechanisms other than arterial atherosclerosis.
