Study Of Morphological Variations In Human Cadaveric Livers

ABSTRACT

Background: Liver is a large gland which occupies a substantial (large) portion of the abdominal cavity of humanbody .It is situated below the right side of diaphragm and mainly occupies the right hypochondrium, epigastriumand part of left hypochondrium. Anatomically it has left and right lobes which are divided by falciparm ligament,fissure for ligamentamvenousm and fissure for ligamentamteres. It has caudate and quardate lobes as the partsof right anatomical lobe Anatomical variations in cadaveric livers are present in form of lingular process ofleft lobe, accessory lobe,hypoplastic lobe, accessory fissure and diaphargmatic groove on superior surface ofliver.The knowledge of morphological variations of liver may be useful to surgeon during transplantationphysicians to rule out the liver diseases and radiologist for correct diagnosis.Materials and Methods: The knowledge of morphological variations was observed in 50 livers during the routinedissection and specimen present in department of anatomy.In 50 livers we observed 23 were present withmorphological variation this shows that 46% of liver were abnormal.Conclusion: In the present study it is observed that accessory lobe, hypo plastic lobe, accessory fissure anddiapharmatic grove on superior surface of liver are more common morphological variations .The morphologicalvariations remains asymptomatic but can lead to misinterpretations during surgical and radiological procedure.Thus the present study is useful for radiologists and surgeons to plan the surgical procedures.
