Abstract：Objective To explore the application value of shear wave elastography in monitoring the efficacy of transjugular intrahepatic portosystemic shunt(TIPS).Methods The clinical data of 43 patients who underwent TIPS surgery at Sichuan Provincial People's Hospital were analyzed in this work.Before and after the operation,the diameter and blood flow velocity of portal vein,splenic vein,superior mesenteric vein were measured.At the same time,the thickness of spleen,as well as the shear wave velocity of liver and spleen were measured.With the portal vein pressure gradient as the gold standard,the changes of various indicators before and after the operation were analyzed and compared.Results The diameter of splenic vein,superior mesenteric vein and liver hear wave velocity had no significant change before and after operation(P>0.05).The difference in portal vein diameter was very small,whereas,the blood flow velocity of portal vein,splenic vein and superior mesenteric vein in-creased after TIPS(P<0.05).The portal vein pressure gradient,the thickness of spleen shear wave velocity,and spleen de-creased compared with that before operation(P<0.05).Conclusion The blood flow velocity of portal vein,splenic vein,supe-rior mesenteric vein,spleen thickness,and spleen shear wave velocity can be used as important indicators for monitoring the effi-cacy of TIPS.
