Abstract

Objective To assess the role of portal congestion index (PCI) in prediction of esophageal varices (EV) in hepatitis C virus (HCV)-infected patients. Background Portal hypertension (PH) often develops in HCV-infected patients. EV rupture leads to variceal bleeding, the most lethal complication of cirrhosis. Duplex Doppler ultrasonography of portal vein is a noninvasive method to assess blood flow velocity and portal vein cross-sectional area as a parameter for PH. Patients and methods This study was conducted on 200 HCV-infected patients (116 with EV and 84 without EV). Patients were subjected to complete blood picture, liver and kidney functions, serum electrolytes, viral markers, abdominal ultrasonography, upper gastrointestinal tract endoscopy, and duplex Doppler evaluation of portal vein with calculation of PCI. Results There was a highly significant difference between HCV-infected patients with and without EV regarding PCI (P = 0.0001). At cutoff point of PCI 0.11, the sensitivity, specificity, and accuracy to predict EV were 93, 85.7, and 90%, respectively, with area under the curve 0.889. There was a statistically highly significant positive correlation between PCI and presence of fundal varices and PH gastropathy (P = 0.0001). There was a statistically significant positive correlation between PCI and grades of EV (P = 0.012). Conclusion PCI is useful as a noninvasive predictor of EV in HCV-infected patients.
