To determine if the ultrasound (US) survey of the lower extremity for deep venous thrombosis (DVT) can be curtailed without compromising diagnostic efficacy.
The authors performed 755 US examinations in 721 patients (1,024 lower extremities) referred for suspicion of lower extremity DVT. The full lengths of the deep veins were studied, and findings were categorized at five locations: common femoral vein (CFV), proximal superficial femoral vein (CFV), mid-SFV, distal SFV, and popliteal vein (PV).
Acute thrombus was seen in one or more veins in 131 (17.4%) of the 755 examinations. DVT isolated to a single vein was seen in 28 (21.4%) of the 131 positive examinations: DVT was limited to the CFV in eight studies (61%), to the SFV in six studies (4.6%), and to the PV in 14 studies (10.7%).
DVT limited to a single vein occurs with sufficient frequency that the US screening survey cannot be abbreviated without loss of diagnostic efficacy.
确定在不影响诊断效能的情况下，是否可以缩短对下肢深静脉血栓形成（DVT）的超声（US）检查。
作者对721例（1024条下肢）因怀疑下肢DVT而转诊的患者进行了755次US检查。研究了深静脉的全长，并在五个部位对检查结果进行分类：股总静脉（CFV）、股浅静脉近端（CFV）、股浅静脉中段、股浅静脉远端和腘静脉（PV）。
在755次检查中，131次（17.4%）在一条或多条静脉中发现急性血栓。在131次阳性检查中，28次（21.4%）发现DVT局限于单一静脉：8项研究（61%）中DVT局限于CFV，6项研究（4.6%）中局限于股浅静脉，14项研究（10.7%）中局限于PV。
DVT局限于单一静脉的情况发生频率足够高，以至于在不损失诊断效能的情况下，不能缩短US筛查检查。
