Pericardiacophrenic artery

The pericardiacophrenic artery is a long slender branch of the internal thoracic artery.[1] It anastomoses with the musculophrenic and superior phrenic arteries.[2]

Location

The pericardiacophrenic artery branches from the internal thoracic artery.[1] It accompanies the phrenic nerve between the pleura and pericardium, to the diaphragm.[3] This is where both the artery and the phrenic nerve are distributed.

Function

The pericardiacophrenic arteries travel through the thoracic cavity, and are located within and supply the fibrous pericardium.[4] Along with the musculophrenic arteries, they also provide arterial supply to the diaphragm.[5]
