Abstract:
Purpose To investigate the predictive value of the ratio of the square of the cross-sectional perimeter(C2)to the area(A)of the venous lumen(C2/A)in relation to lower extremity deep venous thrombosis(DVT)among orthopaedic inpatients.Materials and Methods A total of 150 inpatients without DVT from the Orthopedics Department of Xijing Hospital Affiliated to the Air Force Military Medical University were prospectively chosen from June 2020 to June 2021.Before the operation,the parameters including A,C,C2/A,inner diameter values,venous flow velocity and blood flow volume of the common femoral vein(CFV),superficial femoral vein(SFV)and popliteal vein(POV)were examined by ultrasound.After the operation,the formation of thrombus was monitored using ultrasound.Subsequently,the clinical data and ultrasound parameters of the thrombus group and the non-thrombus group were compared.Moreover,the receiver operating characteristic(ROC)curve was plotted to assess the efficacy and cut-off values of each parameter in predicting DVT.Results There were statistically significant differences between the two groups in CFV inner diameter,CFV blood flow,CFV-C,CFV-A,CFV-C2/A,SFV blood flow,SFV-C,SFV-C2/A,POV blood flow,POV-C,POV-A and POV-C2/A(t=2.64-10.41,all P＜0.05).When the cut-off values of the ultrasonic parameters CFV-C2/A,SFV-C2/A,and POV-C2/A were＞16.01,＞16.53,and＞16.54 respectively,the area under the curve for predicting DVT was the largest,which were 0.906,0.920,and 0.870 respectively.The sensitivities were 83.8%,78.4%,and 81.1%respectively,and the specificities were 82.3%,89.4%,and 85.8%respectively.Conclusion The novel ultrasonic parameter C2/A exhibits a relatively high predictive efficacy for DVT,and it is capable of furnishing novel reference information for the implementation of early DVT prevention in the clinical setting.
