2023年10月30日 · The thoracodorsal artery is a terminal branch of the subscapular artery that originates in the axillary region. It runs inferomedially along the lateral border of the scapula, then courses posteriorly passing deep to the latissimus dorsi muscle.

The thoracodorsal artery is a branch of the subscapular artery. It passes inferior-ward upon the surface of the serratus anterior muscle (which it supplies posteroinferiorly to the lateral thoracic artery). [1] It is accompanied by the thoracodorsal nerve along its source. It also supplies the latissimus dorsi. [citation needed]

2024年8月9日 · The thoracodorsal artery is a branch of the subscapular artery that arises within the axilla. It supplies some of the muscles of the upper back and shoulder.

Discover the journey of the thoracodorsal artery, its origin, course, branches, and structures it supplies. Learn about its vital role in the human body.

The thoracodorsal artery is the primary pedicle of the TDAP flap. It branches off the subscapular artery and courses alongside the thoracodorsal nerve. In a small number of patients, the thoracodorsal artery branches directly from the lateral thoracic or axillary arteries 5.

Most commonly, the subscapular artery (SSA) originates as a branch from the third part of the axillary artery (AA), with the circumflex scapular artery (CSA) and thoracodorsal artery (TDA) arising as the two main divisions of the SSA.

The thoracodorsal artery is a branch of the subscapular artery. It travels inferiorly with the thoracodorsal nerve and supplies the latissimus dorsi.

In this paper, we describe the histological and contractile properties of the thoracodorsal artery (TDA), which indirectly feeds the spinotrapezius muscle. Our results demonstrate that the TDA is composed of approximately one-two layers of smooth muscle cells, is highly innervated with adrenergic nerves, and develops spontaneous tone at ...

The thoracodorsal artery arises from the subscapular artery and divides within 2–3 cm of its origin from the third segment of the axillary artery, into the thoracodorsal and circumflex scapular arteries (see Figure 23.2). The subscapular artery may arise from the axillary artery as a common trunk with the posterior circumflex humeral in about ...

Objectives: In this paper, we describe the histological and contractile properties of the thoracodorsal artery (TDA), which indirectly feeds the spinotrapezius muscle. Methods: We used immunolabelling techniques to histologically characterize the TDA while the contractile properties were assessed using pressure arteriography.
