BACKGROUND: @entity1150 ( @entity1150 ) is prevalent in the emergency departments. Nearly 60% of them may lead to @entity1151 . A complete color-flow duplex ultrasound (CFDU), performed by the radiologists, is the most common diagnostic method used to detect @entity1150 . A limited B-mode compression technique (BMCT) can also be useful for the emergency specialists visiting suspicious cases. OBJECTIVES: The purpose of this study was to compare the sensitivity, specificity, and accuracy of a BMCT done by emergency medicine residents with that of a CFDU in diagnosing the proximal @entity1150 of lower extremities. METHODS: This prospective study was conducted on 74 @entity1 (41 @entity1 and 33 @entity1 ) presenting with @entity158 and swollen lower limbs in the emergency department of Imam Khomeini Hospital. First, the affected lower extremity was examined by a BMCT carried out by one of the 2 emergency medicine residents. Then, the CFDU was performed by a radiologist blinded to the results of the BMCT. The sensitivity, specificity, and accuracy of the BMCT were compared with that of the CFDU as a gold standard. RESULTS: The mean age of the @entity1 was 55.16    17.4 years. Positive results were reported in 35 @entity1 (47.3%) using the 2 tests. Compared with CFDU, BMCT had a sensitivity, specificity, accuracy, positive predictive values, and negative predictive values of 100%. CONCLUSION: These findings suggest that BMCT performed by the emergency medicine specialists to diagnose proximal @entity1150 of lower extremities is not only an acceptable method but also less time-consuming when compared with CFDU.
