Morphology and Morphometric Analysis of the Caudate Lobe of Human Liver in Eastern India- A Cross-sectional Cadaveric Study

Introduction: The unique feature of caudate lobe liver is that it has a dual blood supply. Since supplied both by branches portal vein and hepatic artery, may undergo compensatory hypertrophy in different diseases like cirrhosis liver. In addition, excessive localised growth the be manifested as accessory lobules. Previous studies settings had implied an ethnic predisposition affecting morphology All these factors revealed urgent need for further research regarding surface variations morphometry lobe. Aim: To study morphological morphometric measurements human eastern India. Materials Methods: A descriptive cross-sectional was undertaken on 51 formalin fixed adult livers Department Anatomy, Medical College, Kolkata, West Bengal, India from March 2021 to September 2021. Vernier calliper used measure Transverse Diameter (TD), Vertical (VD) Anteroposterior (APD) TD APD diameters Porta hepatis right were also measured. Morphological noted. entered Excel sheet which transported IBM Statistical Package Social Sciences software (SPSS) version 12.0 (free version) analysis. Morphometric analysed using statistics. Caudate (CRL) ratio calculated manually. Results: Most common type shape rectangular (37.25%). Mean values (in cm) TD, VD, 2.4±0.54, 4.7±0.75, 1.9±0.51 respectively. value mean CRL (caudate lobe) 0.30. Conclusion: detailed anatomical knowledge would helpful surgeon suitably plan resections guide radiologist correct interpretation imaging technique.
