Abstract:
Purpose To explore the value of monitoring liver-shear wave elastography(L-SWE)and spleen-shear wave elastography(S-SWE)by two-dimensional shear wave elastography after transjugular intrahepatic portosystemic shunt(TIPS)in predicting stent dysfunction.Materials and Methods A total of 40 patients with hepatitis B cirrhosis in the First Affiliated Hospital of Anhui Medical University from January 2016 to September 2022 who underwent TIPS were retrospectively selected.Among them,22 patients without stent dysfunction within 1 month were included in the normal group,and 18 patients without stent dysfunction within 1 week but with stent dysfunction within 1 month were included in the dysfunction group.The changes of L-SWE and S-SWE were monitored 1 day before operation,1 week and 1 month after operation.Results Mauchly test showed that the data corresponded to sphericity(P>0.05).There was no significant difference in L-SWE within the two groups before and after operation(Ftime=0.003,Ftime×group=0.842,Fgrous=0.027;all P>0.05),while the S-SWE differences were statistically significant(Ftime=51.249,Ftime×group=30.676,Fgrous=11.986;all P<0.01).The S-SWE in the normal group showed a gradually decreasing trend 1 day before operation,1 week after operation and 1 month after operation,and the difference was statistically significant(P<0.05).The L-SWE in the dysfunction group decreased 1 week after operation compared with 1 day before operation(P<0.05),and the L-SWE increased 1 month after operation,with no significant difference compared with 1 day before operation(P>0.05).The difference of ΔS-SWE(1 month after operation-1 week after operation)and ΔS-SWE(1 month after operation-1 day before operation)was statistically significant(t=-2.612,4.368,P<0.05).Conclusion Quantitative measurement of S-SWE before and after TIPS and observation of its variation trend are helpful to estimate whether there is stent dysfunction and evaluate the surgical effect.
