Clinical research on color Doppler ultrasound early prediction of restenosis after ASO operation / 中国现代普通外科进展

ABSTRACT

Objective:To study the early application of color duplex ultrasound in the evaluation of the arteriosclerosis occlusion after operation.Methods:we retrospectively divided the patients with atherosclerotic occlusion after open crossover surgery and endovascular treatment into groups 1( 12 patients ) and group 2( 13 patients ) respectively.In group 1,we assessed the relationship between the separated results of MG and the volume flow measurement in out-flow arteries before and after operation.In group 2,we assessed the relationship between the volume flow measurement in out-flow arter ies and the result of the DSA examination and all the data of group 2 is after treatment.Results:In group 1,the correlation of the separated results of MG and the increased amplitude of volume flow measurement in out-flow arteries was negative(P=0.0138,r=-0.6859).In group 2,the correlation of the volume flow measurement in out-flow arteries and the result of the DSA examination was negative(P=0.0316,r=-0.6198).In the patients after open crossover surgery and endovascular treatment,the MG and the volume of out-flow arteries were the significant hemodynamics index respectively.Conclusion:The color duplex ultrasonic early application is a perfect method in the follow-up of arteriosclerosis occlusion after operation.
