Anatomic Variations of the Right Hepatic Duct: Results and Surgical Implications from a Cadaveric Study

Figure 1

Main variations of the right hepatic duct in Greek cadavers. (a) Typical anatomy of the right hepatic duct (𝑛=48, 65.75%). (b) Ectopic drainage of the right anterior duct into the common hepatic duct (𝑛=11, 15.07%). (c) Triple confluence, the common hepatic duct receives independently the right anterior duct, the right posterior duct, and the left hepatic duct (𝑛=7, 9.59%). (d) Ectopic drainage of the right posterior duct into the left hepatic ductal system (𝑛=3, 4.11%). (e) Ectopic drainage of the right posterior duct into the common hepatic duct (𝑛=2, 2.74%). (f) Ectopic drainage of the right anterior duct into the left hepatic ductal system (𝑛=1, 1.37%). (g) Ectopic drainage of the right posterior duct into the cystic duct (𝑛=1, 1.37%). ra: right anterior; rp: right posterior; lh: left hepatic.
