During a 1-year period, 537 compression ultrasound (CU) examinations were performed in 506 extremities of 485 patients for evaluation of possible deep venous thrombosis (DVT). Decisions regarding therapy were based on the result of this test in both outpatients and inpatients. Doppler ultrasound was also used during the last 7 months of the study, but this procedure did not alter the results obtained with CU alone. Incidental findings (eg, Baker cysts, aneurysms, and lymph nodes) were noted in 42 patients and were thought to be nonthrombotic causes of leg swelling or pain that could not be detected with venography. The reliability and clinical acceptance of CU as a means of diagnosing lower-extremity DVT resulted in a 50% yearly reduction in venography, with a concomitant 130% increase in the number of cases of DVT diagnosed.
在1年的时间里，对485例患者的506个肢体进行了537次加压超声（CU）检查，以评估可能的深静脉血栓形成（DVT）。门诊患者和住院患者的治疗决策均基于该检查结果。在研究的最后7个月也使用了多普勒超声，但该检查并未改变仅使用CU所获得的结果。42例患者发现了偶然病变（如贝克囊肿、动脉瘤和淋巴结），这些被认为是腿部肿胀或疼痛的非血栓性原因，静脉造影无法检测到。CU作为诊断下肢DVT手段的可靠性和临床认可度使静脉造影的年使用量减少了50%，同时诊断出的DVT病例数增加了130%。
