ABSTRACT

@#BACKGROUND: Chronic viral hepatitis is the most important public health problems and main cause of liver fibrosis. Progressive hepatic fibrosis will gradually lead to liver cirrhosis, hepato-cellular carcinoma and liver failure and deaths. Study of liver fibrosis is becomes an essential issue of prevention, prognosis and radical treatment plan. The evaluation of liver fibrosis using ultrasound based-electrographic shear wave elastography (SWE) with elastography point quantification (ElastPQ) is a modern non-invasive method. This study is aimed to evaluate diagnostic value of SWE with ElastPQ feature of liver fibrosis. MATERIAL: A total of 110 patients with chronic viral (B, C and D) infection and 50 healthy controls were involved. Quantitative evaluation of LS was performed by Philips iU 22 ultrasound system with ElastPQ using convex transducer C5-1. RESULTS: In HBV patients: no fibrosis F0 score 7, mean liver stiffness was 3.1±0.28 kPa, mild liver fibrosis F1 score 26, mean LS was 4.9±0.90 kPa, F2 score 4, mean LS was 8.0±0.56 kPa, F3 score 3, mean LS was 11.0±0.83 kPa, and F4 score or liver cirrhosis 2, mean LS was 17±4.3 kPa, respectively. In patients HCV; F0 score -5, mean LS was 3.2±0,08 kPa, F1-36, mean LS was 5.0±0.94 kPa, F2 score-10, mean LS was 8.1±0.90 kPa, F3-10, mean LS was 10.9±1.03kPa, and F4 score 5, mean LS 15.9±2.8kPa, respectively. In patients with HBV, HDV; F0 score-1, liver stiffness was 3.2kPa, F1-13, mean LS was 4.9±0.72 kPa, F2 score 2, mean LS was 8.0±0.56kPa, F3 score, LS was 10.8kPa, F4 score 1, LS was 20.1kPa, respectively. CONCLUSIONS: Shear wave elastography with elastography point quantification technique is a reliable that can to detect of the earlier fibrosis stage in chronic viral hepatitis patients. ElastPQ SWE method is an optimal to monitor liver tissue stiffness in patients with chronic liver diseases.
