Abstract:
ObjectiveTo investigate the clinical value of color Doppler ultrasound examination in the diagonosis of acute and chronic artery occlusion of the extremities.MethodsA review was made on 129 extremetiy artery occlusion patients at Anzhen Hospital during 2006 -2010. 85 cases were male, and 44 cases were female. Age was from 17 to 94 years (average: 62 ±9 years). We analyzed two-dimensional and color Doppler flow imagings of 39 acute occlusion arteries and 97 chronic occlusion arteries. We compared factors including the echoes of artery lumens, the vessel wall structures, hemodynamic parameters of inlet and outlet at the occlusion, and collaterals between groups.ResultsThe factors of depths of vessel wall,internal diameters of ccclusion arteries, proximal resistant index and collaterals were significantly different between groups ( P ＜ 0. 05 ). The internal diameters of acute occlusion arteries were wider than chronic occlusion arteries. The depths of vessel wall, proximal resistant index and collaterals were thinner, smaller,and less than chronic occlusion arteries. The total accurate rate of differential diagnosis for acute and chronic artery occlusion by color Doppler ultrasound was 95.6％.ConclusionsColor Doppler ultrasound is an effective method for the differential diagnosis of acute and chronic artery occlusion of the extremities.
