Radiomics Signature of Hepatic Venous Pressure Gradient (rHVPG) With CT Angiography (CHESS1701)

Not Applicable
Completed
Conditions
Hypertension, Portal
Interventions
Procedure: HVPG measurement
Procedure: CTA
Registration Number
NCT03138915
Lead Sponsor
Nanfang Hospital, Southern Medical University
Brief Summary

This is a prospective, multi-center diagnostic trial conducted at 5 high-volume liver centers in China designed to determine the diagnostic performance of radiomics-based hepatic venous pressure gradient (rHVPG) (investigational technology) by CT angiography (CTA) for noninvasive assessment of the clinically significant portal hypertension (CSPH) in patients with cirrhosis. Direct hepatic venous pressure gradient (HVPG) measurement by means of catheterization of a hepatic vein with a balloon catheter is the gold-standard method to assess the presence of CSPH, which is defined as HVPG≥10 mmHg.

Detailed Description

This is a prospective, multi-center diagnostic trial conducted at 5 high-volume liver centers (302 Hospital of PLA; Beijing Shijitan Hospital; The Third Xiangya Hospital of Central South University; Beijing Youan Hospital; Xingtai People's Hospital) in China designed to determine the diagnostic performance of radiomics-based hepatic venous pressure gradient (rHVPG) (investigational technology) by CT angiography (CTA) for noninvasive assessment of the clinically significant portal hypertension (CSPH) in patients with cirrhosis. Direct hepatic venous pressure gradient (HVPG) measurement by means of catheterization of a hepatic vein with a balloon catheter is the gold-standard method to assess the presence of CSPH, which is defined as HVPG≥10 mmHg.
