Brief Summary
Portal pressure gradient (PPG) above 12 mmHg after transjugular intrahepatic portosystemic shunt (TIPS) increases the risk of portal hypertension complications. Currently, a PPG reduction \<12 mmHg after TIPS is the most consistent threshold associated with almost complete protection from variceal bleeding and ascites. However, the measurement of PPG requires an invasive procedure. A recent study investigated the variations in PPG measurements collected at different time points after placement of TIPS and demonstrated that a time point of at least 24 hours after which PPG values were best maintained (early PPG). It is of great clinical value to propose that an immediate PPG measurement fail to accurately identify the risk of decompensated event. And early PPG would change the decision making for re-intervention or not. However, the repeated invasive examination is extremely difficult to follow in clinical practice worldwide. The prospective multicenter trial aims to assess the diagnostic performance of a virtual imaging-based early portal pressure gradient (vePPG) (investigational technology) from CT angiography and Doppler ultrasound with invasive early PPG measurement as reference. The study participants with portal hypertension will be prospectively recruited at 10 high-volume liver centers in China.
