The first purpose was to test the assumption that ultrasound (US) examination of the asymptomatic leg was unnecessary. The second was to confirm the absence of deep venous thrombosis (DVT) in patients with bilateral symptoms.
Four hundred eighty-eight patients were evaluated at a peripheral vascular laboratory for signs and symptoms of DVT. All patients then underwent bilateral color Doppler US of their leg veins.
Ninety-four patients had no lower extremity symptoms. Of these, 73 had no DVT, 11 had unilateral DVT, and 10 had bilateral DVT. Of 245 patients with unilateral symptoms, 180 had no DVT, 44 had ipsilateral DVT, three had contralateral DVT, and 18 had bilateral DVT. Of 149 patients with bilateral symptoms, 114 had no DVT, 10 had unilateral DVT, and 25 had bilateral DVT.
The frequent finding of bilateral DVT and unsuspected contralateral DVT in patients with unilateral symptoms, and the even more frequent finding of DVT in patients with bilateral symptoms, clearly indicates that both categories of patients need to be evaluated with bilateral US.
第一个目的是检验无症状腿部超声（US）检查不必要这一假设。第二个目的是确认双侧有症状患者不存在深静脉血栓形成（DVT）。
488例患者在周围血管实验室接受DVT体征和症状评估。然后所有患者均接受双侧腿部静脉彩色多普勒超声检查。
94例患者无下肢症状。其中，73例无DVT，11例有单侧DVT，10例有双侧DVT。在245例有单侧症状的患者中，180例无DVT，44例有同侧DVT，3例有对侧DVT，18例有双侧DVT。在149例有双侧症状的患者中，114例无DVT，10例有单侧DVT，25例有双侧DVT。
单侧症状患者中频繁发现双侧DVT和未被怀疑的对侧DVT，以及双侧症状患者中更频繁地发现DVT，清楚地表明这两类患者都需要接受双侧超声评估。
