Scalenovertebral Triangle [Trigonum (Spatium) Scalenovertebrale]

The scalene-vertebral triangle (trigonum, that is, “space”) is one of the most important anatomical areas of the chest, which is directly connected to the human neck. This area is located in the sternocleidomastoid region and is limited by three structures, the anterior scalene, longus muscles of the neck and the dome-shaped sinus of the pleura.

Here in this triangle there is not one artery, but a whole series of structures, such as the subclavian, vertebral, internal mammary arteries, thyroid parasitic branch and simental branch,

The staircase-vertebral triangle (trigonum spatium scalenovertebria) is an area in the sternoclavicular region of the neck. The area is located between the anterior scala, the long oblique suture, and the dome of the pleura. The boundaries of the formation extend from the top of the medial edge of the clavicle in front to the lower edge of the rib at the point of the neck behind. This area is considered one of the most important areas of the neck. Here
