La arteria torácica lateral (arteria torácica larga) es una rama de la arteria axilar. Irriga varias estructuras de la axila y la pared torácica anterior. Trayecto La arteria torácica lateral se origina en la segunda parte de la arteria axilar (posterior al músculo pectoral menor). Discurre verticalmente hacia abajo a lo largo del borde lateral del músculo pectoral menor. A lo largo de su trayecto, da lugar a varias ramificaciones pequeñas que irrigan diversas estructuras de la axila y la pared torácica anterior. Por lo general, termina a la altura del quinto espacio intercostal y forma una anastomosis con la arteria torácica interna.

Pasarse a la versión Premium Frequent questions What is the lateral thoracic artery? The lateral thoracic artery is a branch of the axillary artery that supplies blood to various structures in the axilla and the anterior thoracic wall. It originates from the second part of the axillary artery and descends vertically along the lateral border of the pectoralis minor muscle. What structures are irrigated by the lateral thoracic artery? The lateral thoracic artery provides blood supply to the axillary lymph nodes, breasts, skin of the lateral thoracic wall, and several muscles including the serratus anterior, pectoralis major, pectoralis minor, and subscapularis. Its role is crucial in maintaining the vascular health of these areas. Where does the lateral thoracic artery originate? The lateral thoracic artery originates from the second part of the axillary artery, located posterior to the pectoralis minor muscle. This positioning is important for its subsequent course and the structures it supplies. How does the lateral thoracic artery terminate? The lateral thoracic artery typically terminates at the level of the fifth intercostal space, where it forms an anastomosis with the internal thoracic artery. This connection enhances blood supply to the thoracic region. What is the clinical significance of the lateral thoracic artery? The lateral thoracic artery is clinically significant as it supplies vital structures in the axilla and anterior thoracic wall, making it important during surgical procedures in the area. Understanding its course and branches can help prevent complications such as bleeding or ischaemia. Valora este artículo
