According to international guidelines, Hepatic Venous Pressure Gradient is the gold standard technique for portal hypertension measurement, but it is invasive and poorly available. Currently, surveillance of oesophageal/gastric varices is performed by upper gastrointestinal endoscopy. More recently, non-invasive tools to estimate portal hypertension have been developed and, among them, ultrasound elastography has been proposed as a technique to stratify patient risk to have portal hypertension. Aim of this study is to evaluate the relationship between ultrasound evaluation (D-CEUS + elastography) and endoscopic parameters predictive of clinically significant portal hypertension in patients with liver cirrhosis.
