Multiple variations of the subhepatic hepatobiliary vasculature

Proper knowledge of the anatomy of hepatobiliary vasculature and its possible variations are important for surgeons, radiologists and other clinicians. We noticed few variations in the branching pattern of hepatic artery, portal vein and cystic artery during routine anatomy dissection classes. The variations include an additional left hepatic artery, which was found communicating with left branch of portal vein, and an additional cystic artery.
