Significance of Extra Hepatic Portal Vein Variations in Hepatopancreatic Surgeries

July 5, 2021 Medicine and Medical Science 0

Introduction: When performing pancreas and duodenum surgeries, it is critical to understand the variations in the portal vein’s path. It can also be used to treat traumatic mesentery rupture. Awareness of portal vein variations is critical in surgical resection and transplantation, especially during pretreatment planning, to reduce the complication rates of the surgical and radiological treatments. Furthermore, an in-depth understanding of portal vein variations is essential in determining the technical feasibility of surgical interventions such as liver transplantation, portal vein embolization prior to hepatectomy, and postoperative care. The purpose of this study is to examine the anatomical variations of the portal vein, correlate the findings with clinical problems, and provide a good ontological explanation. Materials and Methods: Twenty-four cadavers embalmed in 10% formalin were obtained from the department of anatomy and dissected for this study. Variations were meticulously cleaned and photographed. Among the variations observed were the formation of the portal vein by the confluence of the superior mesenteric, inferior mesenteric, and splenic veins (1 case), as well as the inferior mesenteric vein terminating in the superior mesenteric vein (6 cases). Conclusion: The purpose of this study was to determine the approximate percentage of incidence of major variations in portal vein formation. By being aware of such variations prior to major abdominal procedures, it is possible to avoid severe intraoperative hemorrhage.
