Abstract

Chronic consumption, obesity, hepatitis C and hepatitis B are the causes of the ongoing rise in chronic liver disease prevalence. Portal hypertension and its consequences cause considerable morbidity and death in cirrhotic individuals. Ultrasound methods such as duplex ultrasonography, spectral Doppler imaging, colour Doppler imaging, and power Doppler imaging are the modalities of choice in portal hypertension imaging because they are noninvasive, quick, and extremely sensitive and specific. The Child's classification, as modified by Pugh et al., is recognised as an essential prognostic indicator for assessing liver damage. Ultrasonography with colour Doppler aids in the evaluation of portal hypertension and the identification of sinusoidal, pre-sinusoidal, and post-sinusoidal causes of portal hypertension. It also allows for the detection of sequelae such as portal vein thrombosis and oesophageal varices with reasonable precision. Given these advantages and the paucity of literature on the role of colour Doppler, the current study was designed to assess the spectrum of colour Doppler sonographic findings, as well as the Hepatic Vein Damping Index (DI) and its correlation with the severity of liver dysfunction (Child Pugh score) in patients with portal hypertension. Aims and objectives: To determine if colour Doppler is more specific than grey scale ultra sound results in individuals with portal hypertension. Materials and methods :The study is a cross-sectional design. Outpatients and inpatients with radiology in a tertiary care hospital in Hyderabad. Study Duration: 18 months.During the study period, patients clinically diagnosed of having portal vein hypertension underwent Colour Doppler USG. The clinical and radiological data from the trial were documented in the medical records. Results: In the current investigation, cirrhosis was detected in a significant percentage of the patients, who also had alcoholic liver disease. Other causes included portal vein blockage, cancer, and left sided portal hypertension. The high incidence of alcohol drinking in the geographic region where the study was conducted may have contributed to alcoholic liver disease being the most common cause of liver cirrhosis in our study. Discussion: During the research study, a total of 40 patients met the selection criteria. Males outnumbered females in the current research. More than over half of the participants in this research were between the ages of 51 and 60 years. In the current investigation, cirrhosis was detected in 62% of the patients, with 95% having alcoholic liver disease. Other causes included portal vein blockage, cancer, and left sided portal hypertension. Conclusion: Colour Doppler sonography is a powerful non-invasive option that not only gives accurate information in localising and characterising portal veins in patients with portal hypertension, but it is also useful in determining the existence of distinct portosystemic collaterals. In terms of the Child Pugh score, the hepatic vein damping index (DI) corresponds well with the degree of liver disease.
