Pericardiacophrenic veins

Pericardiacophrenic Veins

The Pericardiacophrenic Veins are small veins that accompany the Pericardiacophrenic arteries along the lateral borders of the heart. They are part of the cardiovascular system and play a crucial role in the circulation of blood in the body.

Anatomy

The Pericardiacophrenic Veins originate from the pericardium, the double-walled sac containing the heart and the roots of the great vessels. They run along the phrenic nerves, descending vertically on the lateral borders of the heart. They drain into the brachiocephalic veins, which are large veins that return oxygenated blood from the upper limbs, neck, and head to the heart.

Function

The primary function of the Pericardiacophrenic Veins is to drain the blood from the pericardium and the central tendon of the diaphragm. They work in conjunction with the Pericardiacophrenic arteries, which supply oxygenated blood to the same areas.

Clinical Significance

Abnormalities or damage to the Pericardiacophrenic Veins can lead to various medical conditions. For instance, thrombosis in these veins can cause pericarditis, an inflammation of the pericardium, or pleurisy, an inflammation of the pleura that can cause chest pain and difficulty breathing.
