 Another name used to refer to this region is Calot's triangle, after Jean-François Calot.Calot's original description of the triangle in 1891 included the cystic duct, the common hepatic duct, and the cystic artery (not the inferior border of the liver as is commonly believed).The hepatocystic triangle is the area bound by the cystic duct, common hepatic duct, and the liver margin.
