The superior thoracic aperture is essentially a hole surrounded by a bony ring, through which several vital structures pass. It is bounded by: the first thoracic vertebra (T1) posteriorly; the first pair of ribs laterally, forming lateral C-shaped curves posterior to anterior; and the costal cartilage of the first rib and the superior border of the manubrium anteriorly.
There are two openings of the thoracic cavity, a superior thoracic aperture known as the thoracic inlet and a lower inferior thoracic aperture known as the thoracic outlet. The thoracic cavity includes the tendons as well as the cardiovascular system which could be damaged from injury to the back, spine or the neck.
Thoracic outlet syndrome (TOS) is a condition in which there is compression of the nerves, arteries, or veins in the superior thoracic aperture, the passageway from the lower neck to the armpit, also known as the thoracic outlet. [1] There are three main types: neurogenic, venous, and arterial. [1]
The bony skeletal part of the thoracic wall is the rib cage, and the rest is made up of muscle, skin, and fasciae.. The chest wall has 10 layers, namely (from superficial to deep) skin (epidermis and dermis), superficial fascia, deep fascia and the invested extrinsic muscles (from the upper limbs), intrinsic muscles associated with the ribs (three layers of intercostal muscles), endothoracic ...
The mediastinum (from Medieval Latin: mediastinus, lit. 'midway'; [2] pl.: mediastina) is the central compartment of the thoracic cavity.Surrounded by loose connective tissue, it is a region that contains vital organs and structures within the thorax, namely the heart and its vessels, the esophagus, the trachea, the vagus, phrenic and cardiac nerves, the thoracic duct, the thymus and the lymph ...
Thrombolysis is typically performed prior to first rib resection for venous thoracic outlet syndrome. First rib resection is indicated for venous , arterial , and neurogenic TOS. [ 1 ] In all cases, the goal of the operation is to increase the dynamic space between the chest wall and the clavicle , through which the subclavian vein, artery, and ...
The sternocostal triangle (foramina of Morgagni, Larrey's space, sternocostal hiatus, etc. [1]) are small zones lying between the costal and sternal attachments of the thoracic diaphragm. No vascular elements are present within this space. [2] The borders of this space are: Medial: the lateral border of the sternal part of the diaphragm
thoracic outlet syndrome Adson's sign is the loss of the radial pulse in the arm by rotating head to the ipsilateral side with extended neck following deep inspiration. It is sometimes used as a sign of thoracic outlet syndrome (TOS). [ 1 ]
