Pericardiophrenic artery

The pericardiophrenic artery, also known as the pericardiacophrenic artery, is a branch of the internal thoracic artery that runs to the diaphragm where it anastamoses with both the musculophrenic and superior phrenic arteries. It runs with the phrenic nerve and pericardiophrenic vein between the pleura and the pericardium, supplying the pericardium and the diaphragm.
