CEUS in evaluating on the function of stent after TIPS in patients with portal hypertension in cirrhosis / 中国介入影像与治疗学

ABSTRACT

Objective: To investigate the value of CEUS in evaluating on the function of stent after TIPS in cirrhosis patients with portal hypertension. Methods: Totally 107 cirrhosis patients with portal hypertension who underwent TIPS were selected, and the function of stent were observed with CDFI and CEUS. Taken DSA results as golden standards, the diagnostic efficiency of CDFI and CEUS were evaluated and compared. Results: The sensitivity, specificity, positive predictive value and negative predictive value of CEUS in evaluation on function of stent after TIPS was 90.00% (9/10), 100% (16/16), 100% (9/9) and 94.12% (16/17), while of CDFI was 64.71% (11/17), 80.00% (68/85), 39.29% (11/28) and 91.89% (68/74), respectively. Taken DSA results as gold standards, AUC of CDFI and CEUS was 0.542 and 0.958 (P<0.01). Conclusion: CEUS has high sensitivity and specificity for judgment of stent function after TIPS, which can provide objective and accurate information for clinical practice.
