Background: Considering the very dangerous complications of deep vein thrombosis in critically ill patients, its early identification is very important.
Method: This was a cross-sectional diagnostic value study that was conducted on 70 patients over 18 years of age who had lower limb edema or scored higher than 1 according to the Wells criteria and were referred to the edalatian Emergency Department of Imam Reza Hospital and Qaem Hospital from the fall of 2017 to the fall of 2018; The ultrasound compression test was first performed at two points and then at the third point by trained specialists in the emergency room.
Results: IIn the two-point compression ultrasound examination, it was observed that DVT was reported positive in 59 cases and no false positive cases were observed. Also, DVT was not positive in only 6 cases and true negative was observed in 5 cases. The sensitivity, specificity, positive predictive value and negative predictive value of Compression 2point ultrasound were reported as 90%, 100%, 100% and 45%, respectively. In the three-point compression ultrasound examination, DVT was reported positive in 63 cases and no false positive cases were observed. Also, negative DVT was reported in only 2 cases and true negative cases were also observed in 5 cases. The sensitivity, specificity, positive predictive value, and negative predictive value of three-point compression ultrasound were reported as 96%, 100%, 100%, and 71%, respectively. In the end, the delong’s test showed that there is a significant difference between two-point compression and three-point compression ultrasound in the diagnosis of lower limb vein thrombosis (P<0.01).
Conclusion: Based on the findings of our study, it seems that performing two-point and three-point ultrasound in the emergency room for diagnosing DVT has high sensitivity and accuracy, and performing three-point ultrasound is preferable to two-point.
