Abstract:
Objective To investigate the characteristics of hemodynamic changes in superior mesenteric artery(SMA)of patients with acute suppurative appendicitis(ASA)to facilitate the diagnosis of ASA.Methods Ninety-three ASA patients diagnosed by ultrasound and confirmed by pathology in some hospital from January 2015 to December 2022 were enrolled into an ASA group,and 88 soldiers without abnormalities in the annual physical examination at the hospital in 2021 were divided into a control group,and the two groups were compared in terms of SMA hemodynamic indexes including peak systolic velocity(PSV),end diastolic velocity(EDV),resistance index(RI)and systolic/diastolic ratio(S/D).The statistically significant data of the above indexes were selected to draw the ROC curve and obtain the cut-off values.SPSS 22.0 software was used for statistical analysis.Results The PSV was(212±69)cm/s in the ASA group and(118±26)cm/s in the control group,with statistically significant differences(P＜0.05),and the two groups had the differences in EDV,RI,and S/D not statistically significant(P＞0.05).The ROC curve was plotted based on the PSV data,and a cutoff value of 238 cm/s was obtained with an AUC of 0.714.Conclusion Ultrasound examination of SMA hemodynamic changes in suspected ASA patients facilitates a definitive diagnosis and is of guidance for clinical treatment.[Chinese Medical Equipment Journal,2023,44(10):64-67]
