Vein Intercostal Upper Right

Upper right intercostal vein: anatomical features and functions

The right intercostal vein, also known as v. intercostalis superior dextra, or PNA, is one of the veins that runs between the ribs and drains blood from the muscles of the chest. Its location is on the right side of the chest and it runs along the upper ribs.

Anatomical features

The upper right intercostal vein begins from the venous plexus in the region of the head of the ribs, which are located on the right side of the chest. It flows along the upper ribs, passing between them, and merges with the veins of the chest wall. The right superior intercostal vein is important for draining blood from the chest muscles and ensuring normal blood circulation.

Functions

The right intercostal vein plays an important role in ensuring normal blood circulation in the chest. It drains blood from the muscles of the chest and directs it to the right side of the heart. In addition, it is an important element of the thoracic venous system, which ensures the return flow of blood from the head and upper extremities.

Conclusion

The upper right intercostal vein is important for the normal functioning of the body. Its anatomical features and functions are associated with a wide range of diseases that can lead to poor circulation in the chest. Therefore, understanding the role of this vein and its significance for the body are important aspects for doctors of various specialties.

The superior right intercostal vein (hereinafter referred to as the MRV vein) in anatomy corresponds to a fourth-order vein among about 50 branches that arise from the ascending vein of the thoracic region, extend onto the inner surface of the eighth-ninth costal cartilages of the rib and flow freely into the brachiocephalic vein.

All branches from the ascending thoracic vessel to the left main trunk are divided; their aponeurotic ligaments in relation to this highway are located at an angle to the right and are located at the back above and to the left. The MRV vein, located in the uppermost section, has a left and medial direction. It is directed predominantly posteriorly, going around the rib, but sometimes it moves upward or laterally, giving tributaries to the intercostal veins of the second and third rib.

The anterior interpleural superior right superior vein communicates with nine right branches from this branch of the general blood flow into the right atrium through both azygos and semi-azygos veins. In addition, the right branch of the blood flow from the MRV flows into the superior bronchial artery, a small vessel that carries blood from the pulmonary artery system to the process of the internal carotid artery to the transverse process of the pharynx and is carried to the left subclavian branch. The last branches retell the azygos vein along the trunk of the posterior thoracic vein.
