Abstract

Abstract:

Objective To investigate the significance of clinical probability model Wells' score combined with D-dimer（DD）determination for screening deep vein thrombosis（DVT）. Methods A total of 127 patients with suspected DVT were enrolled for Wells' score,and the prediction probability score was obtained. DD level before treatment was determined. According to the color Doppler flow imaging and multislice CT venography,the further diagnosis was performed. Results The positive rate of Wells' score for screening DVT was 30.7%,and the positive rate of DD determination was 36.2%. The positive rate of combined determination for screening DVT was 47.2%,which was higher than those of Wells' score and DD determination（P<0.05）. The performance of DD determination was better than that of Wells' score（P<0.05）. Conclusions Wells' score combined with DD determination can help for the early screening of DVT,reduce miss diagnosis rate,and effectively eliminate DVT.
