Learning objectives: Explain a systematic way to explore TIPS on Doppler ultrasound. Review the normal characteristic of TIPS on ultrasound (Doppler color and spectral). Dysfunctional TIPS criteria on Doppler ultrasound (Doppler color and spectral). When to realize ultrasound on follow up after TIPS.
Background: Transjugular Intrahepatic Portosystemic Shunt (TIPS) is one of the most complex procedures performed by radiologist. It consist in creating an artificial route to comunicate portal venous system with hepatic veins through the liver parenchyma. With this, the objective is to relieve the high intraabd[...]
Findings and procedure details: TIPS (Transjugular Intrahepatic Portosystemic shunt) is a procedure that has been performed in medicine for more than 20 years ago. Consist in the creation of an artificial pathway to connect the portal venous system directly into systemic circulation through hepatic veins which generate a[...]
Conclusion: TIPS is nowadays a procedure performed often in interventional radiology services. Every radiologist should identify signs of dysfunctional TIPS on Doppler ultrasound. Identification of signs of dysfunctional TIPS will improve outcome of patients with chirrosis and portal hypertension changing manag[...]
