Abstract:

Objective To analyze the value of monitoring changes in ultrasound elastography parameters before and after treatment with catheter contact thrombolysis (CDT) combined with AngioJet mechanical thrombus aspiration (ART) in patients with acute lower extremity deep vein thrombosis (DVT) for the assessment of efficacy. Methods One hundred patients with DVT admitted to Hengshui people′s hospital from August 2021 to August 2022 were selected, and all patients received CDT combined with ART and postoperative medication for 10 d. Patients were observed for swelling of the affected limb before and after 10 d of treatment, ultrasound elastography parameters. Patients were divided into ineffective group and effective group according to different curative effects, and baseline data and ultrasonic elastography parameters before treatment were compared between the two groups; the subject operating curve (ROC) was plotted, and the area under the curve (AUC) values were calculated to test the predictive value of ultrasound elastography parameters for treatment ineffectiveness in DVT patients; Spearman's analysis of ultrasound elastography parameters and treatment ineffectiveness in DVT patients was performed using a bivariate correlation variable The correlation between ultrasound elastography parameters and treatment ineffectiveness in DVT patients was analyzed using the bicorrelation variable Spearman. Results After 100 patients with DVT were treated with CDT combined with ART, 34(34.00%) were effective, 53(53.00%) were effective, and 13(13.00%) were ineffective; After treatment, the circumference difference of the affected side thigh and the circumference difference of the affected side calf of DVT patients were smaller than before treatment, and the ultrasonic elastography score, strain value and Young's modulus value were lower than before treatment (P < 0.05). The ultrasonic elastography score, strain value and Young's modulus in the ineffective group were higher than those in the effective group before treatment (P < 0.05). The ROC curve shows that the ultrasonic elastography score, strain value, Young's modulus level and combined detection have certain predictive value in predicting the clinical efficacy of DVT patients (AUC = 0.803, 0.793, 0.771), and the combined detection is the highest (AUC = 0.946). Among them, the combined test was the highest; using Spearman analysis of dual correlation variables, the results showed that ultrasound elastography score, strain value, and Young's modulus value were positively correlated with treatment ineffectiveness in patients with DVT (r > 0, P<0.05). Conclusion Ultrasound elastography parameters can effectively predict clinical outcomes after CDT combined with ART in DVT patients, and changes in ultrasound elastography parameters were positively correlated with treatment ineffectiveness.
