Pericardiacophrenic artery

The pericardiacophrenic artery is a long slender branch of the internal thoracic artery. It accompanies the phrenic nerve, between the pleura and pericardium, to the diaphragm, to which it is distributed. It anastomoses with the musculophrenic and superior phrenic arteries.

On their course through the thoracic cavity, the pericardiacophrenic arteries are located within and supply the fibrous pericardium.[1] Along with the musculophrenic arteries, they also provide arterial supply to the diaphragm.[2]
