Learning objectives To know the normal imaging findings of TIPS on Doppler ultrasound. To identify the ultrasonographic signs of stent dysfunction. To review cases from our hospital.
Read more Background Portal hypertension is defined as an increase in the portal pressure gradient (portal pressure minus inferior vena cava pressure) that exceeds 5 mmHg. It is considered to be clinically significant when it exceeds 10mmHg, at which point complications begin to appear. The most common cause is chronic liver disease1.The Transjugular Intrahepatic Portosystemic Shunt (TIPS) consist in creating a direct connection between the portal vein and a hepatic vein through the liver tissue to reduce portal pressure and thus, to treat...
Read more Findings and procedure details TIPS dysfunction refers to the narrowing or blockage of the stent caused by either intimal hyperplasia or in-situ thrombosis, typically occurring in the cephalic portion of the stent. It is crucial to monitor TIPS closely due to the high incidence of stent stenosis, which ranges from 8% to 20% of patients within the first year. This condition is associated with significant morbidity and mortality due to the recurrence of portal hypertension complications. Early diagnosis of TIPS dysfunction has been shown...
Read more Conclusion The Doppler ultrasound is essential for monitoring the long-term performance of TIPS. If there are ultrasound findings indicating dysfunction, a venography should be performed to confirm the status of the stent. Early diagnosis of TIPS dysfunction is associated with a significant reduction in morbidity and mortality for these patients.
