To prospectively assess changes in spleen stiffness and splenoportal venous flow before after transjugular intrahepatic portosystemic shunt (TIPS) placement.We evaluated measured by the mean shear wave velocity with acoustic radiation force impulse imaging color Doppler sonography 12 patients (mean age ± SD, 42.6 11.0 years; range, 29-65 years) who underwent TIPS placement for portal hypertension gastroesophageal bleeding. The angle-corrected at main splenic veins were 1 day 3 to 9 days interval, 6.0 1.95 days; 4-10 days) compared vein pressure during procedure.There was a significant difference (25.34 6.21 versus 15.66 6.07 mm Hg; P = .0005). After TIPS, decreased significantly all cases (3.50 0.46 3.15 0.39 m/s TIPS; .00015). increased (22.21 4.13 47.25 12.37 cm/s; .0000051). index 25.57 6.98 cm/s 55.99 21.27 cm(2), respectively, 35.72 11.10 50.11 21.12 cm(2) (P .0004 .003).A decrease increase occurred reduced placement. Hence, both parameters can be used as noninvasive quantitative markers monitoring function
