ABSTRACT
Objective To discuss the diagnostic value of distal subclavian artery flow velocity tracing for proximal segment severe stenosis.Methods 56 cases with 112 subclavian arteries were examed by ultrasonography and multidetector CT angiography respectively,then the flow velocity tracing of distal subclavian arteries had been compared with CT results.Results In all 112 subclavian arteries,there were 37without proximal segment stenosis,32 with mild stenosis,12 with moderate stenosis,and 31 with severe stenosis.Innominate arteries and other parts of subclavian arteries had no stenosis.In diagnosis of subclavian artery proximal severe stenosis using single phase single peak waveform,the sensitivity,specificity,positive likelihood ratio,and negative likelihood ratio were 83.9 %,96.3 %,22.7,0.063 respectively.The sensitivity,specificity,positive likelihood ratio,and negative likelihood ratio were 100 %,93.8 %,16.1,0 respectively,in terms of diagnosis by application of acceleration time ≥0.11s.Conclusions The statistics of acceleration time ≥0.11 s and single phase single peak waveform have high application value in diagnosis of subclavian artery severe stenosis respectively.
