Abstract:
ObjectiveTo investigate the value of advanced dynamic flow (ADF) versus color Doppler flow imaging (CDFI) in evaluating stent patency after transjugular intrahepatic portosystemic shunt (TIPS). MethodsA total of 60 post-TIPS patients who underwent ADF, CDFI, and contrast-enhanced ultrasound (CEUS) in Shengjing Hospital of China Medical University from September 2016 to May 2018 were enrolled. The grade of the patency of TIPS stent was evaluated according to the results of ADF, CDFI, and CEUS. With the results of CEUS as the gold standard, the Kappa test was used to examine the consistency between ADF and CEUS results, as well as between CDFI and CEUS results, the Z test was used as the hypothesis testing of kappa value. ResultsThere was extremely strong consistency between ADF and CEUS in evaluating stent patency after TIPS (Kappa=0.902, P＜0.05), while there was moderate consistency between CDFI and CEUS in evaluating stent patency after TIPS (Kappa=0423, P＜0.05). The Z test found that the difference was statistically significant (P＜0.05). ConclusionCompared with CDFI, ADF has a higher value in evaluating stent patency after TIPS and has certain clinical significance.
