Abstract

The liver is a complex, highly vascular organ where vascular anatomical variations are the norm. This study aimed to analyse hepatic vascular anatomical variations in a single study, thereby helping us understand the prevalence of hepatic vascular anomalies in the population served by our institution. Method: Abdominal cavities of 16 embalmed adult human cadavers were dissected to investigate the variation in the origin, number, and branching patterns of hepatic arteries Conclusion: The significance of these variants must be considered during preoperative planning and the intra-arterial infusion of targeted drugs. This study further accentuates the importance of proper medical imaging and documentation to ensure the best treatment for each patient.
