Abstract (2. Language): 
Introduction: Caudate lobe is a well demarcated anatomic segment of liver that has independent vessels in the form of portalvenous and hepatic arterial branches. Taking into consideration clinical importance of this lobe in metastasis, cirrhosis and hepatic resections a morphological study was carried out on caudate lobe of fifty liver specimens. The present study was planned to assess the anatomical independence of caudate lobe from rest of the liver and its importance in calculating the ratio for cirrhosis. Material and methods: All parameters of caudate lobe such as size, transverse diameter were measured using vernier caliper and surface area was calculated using butter paper. Biliary drainage and venous supply were noted by gross dissection. Observations and results: Portal venous supply only from left portal vein was found in 25/50 (50%) cases, from both right as well as left vein was found in 14/50(28%) cases, from both left portal vein and junction of two veins in 5/50(10%) cases, only from right portal vein in 3/50 (6%) cases, from the junction of two veins in 1/50(2%) cases, from left portal vein, right portal vein and also from junction of two in 1/50(2%) cases and from main portal trunk in 1/50(2%) cases. Conclusion: The degree of anatomical independence of caudate lobe was assessed and reaffirmed. Its importance in calculating the ratio for cirrhosis on USG was reviewed.
