目的 探讨锁骨下动脉远心端血流流速曲线对近心端重度狭窄的诊断价值.方法 对56例患者的112条锁骨下动脉分别进行超声和多层螺旋CT检查,然后将锁骨下动脉远心端血流流速曲线与CT检查结果进行对比分析.结果 112条血管中,锁骨下动脉近心端无狭窄者37条,轻度狭窄者32条,中度狭窄者12条,重度狭窄者31条.无名动脉、锁骨下动脉中段及远心端未见狭窄.应用单相单峰波形诊断锁骨下动脉近心端重度狭窄的敏感性、特异性、阳性似然比、阴性似然比分别为83.9％、96.3％、22.7、0.063;应用加速时间≥0.11s诊断锁骨下动脉近心端重度狭窄的敏感性、特异性、阳性似然比、阴性似然比分别为100％、93.8％、16.1、0.结论 锁骨下动脉远心端血流加速时间≥0.11s和单相单峰波形对诊断近心端重度狭窄均有较高的应用价值.
目的 探討鎖骨下動脈遠心耑血流流速麯線對近心耑重度狹窄的診斷價值.方法 對56例患者的112條鎖骨下動脈分彆進行超聲和多層螺鏇CT檢查,然後將鎖骨下動脈遠心耑血流流速麯線與CT檢查結果進行對比分析.結果 112條血管中,鎖骨下動脈近心耑無狹窄者37條,輕度狹窄者32條,中度狹窄者12條,重度狹窄者31條.無名動脈、鎖骨下動脈中段及遠心耑未見狹窄.應用單相單峰波形診斷鎖骨下動脈近心耑重度狹窄的敏感性、特異性、暘性似然比、陰性似然比分彆為83.9％、96.3％、22.7、0.063;應用加速時間≥0.11s診斷鎖骨下動脈近心耑重度狹窄的敏感性、特異性、暘性似然比、陰性似然比分彆為100％、93.8％、16.1、0.結論 鎖骨下動脈遠心耑血流加速時間≥0.11s和單相單峰波形對診斷近心耑重度狹窄均有較高的應用價值.

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.
