U.S., April 29 -- ClinicalTrials.gov registry received information related to the study (NCT07554183) titled '4D-Flow MRI Assessment of Portal Hypertension and TIPS Outcomes in Cirrhosis' on March 18.
Brief Summary: PORTAL-4D is a prospective, interventional, non-randomized, parallel-group diagnostic study conducted at Pitie-Salpetriere Hospital (Paris, France).
Portal hypertension is the main driver of hepatic decompensation and is associated with ascites, variceal bleeding, hepatic encephalopathy, and reduced survival. The current gold standard for assessing portal hypertension is the invasive hepatic venous pressure gradient (HVPG) measurement performed via the transjugular route. However, HVPG is invasive, operator-dependent, and limi...
