* Calot’s triangle (cystohepatic triangle) is a small anatomical space in the abdomen.
* It is located at the porta hepatis of the liver – where the hepatic ducts and neurovascular structures enter/exit the liver.
* The borders are as follows:
– Medial – common hepatic duct.
– Inferior – cystic duct.
– Superior – inferior surface of the liver.
* The above differ from the original description of Calot’s triangle in 1891 – where the cystic artery is given as the superior border of the triangle.
* The modern definition gives a more consistent border (the cystic artery has considerable variation in its anatomical course and origin).
