    INCIDENCE OF FORMATION OF COMMON TRUNK IN HEPATIC VEINS
    D. Singh, S. Sandeep, S. Ritu

    Introduction- Liver has the unique capacity of regeneration. In the era of increasing liver surgeries, resections are gaining importance for treating conditions like hepatocellular carcinomas and split liver transplantations. This study is an attempt to provide useful assistance for hepatic surgeons in phases of operative planning and vascular control maneuvers required in liver surgery. Materials and Methods- The study was conducted on 30 specimens of liver from well embalmed cadavers in the department of Anatomy of Dayanand Medical College and Hospital, Ludhiana and of Adesh Institute of Medical Sciences and Research, Bathinda. The livers were studied radiologically followed by dissection. The course and ramifications of major hepatic veins were studied. Observations: Out of 30 livers studied the findings were- There were three major hepatic veins-Right, Middle and Left. The formation of common trunk was found only in one liver. The trunk was found between right and middle veins. In rest of the livers , the major hepatic veins drained into Inferior Vena Cava independently. Conclusion- Resection of liver due to tumours or fulminant failure can be complicated by massive haemorrhage or air embolism. This could be due to difficulty in identifying path of the hepatic veins. The complicated nature of liver’s vascular supply emphasizes the study of variations in their course and ramifications. This information may be useful to hepatologists, hepatic surgeons while planning segmental resection of the liver, and to radiologists planning diagnostic and interventional procedures on hepatic venous system. Key words-hepatic veins, split liver transplantations, hepatocellular carcinomas, common trunk
