The thoracic duct drains into the left subclavian vein, [3] near its junction with the left internal jugular vein.It carries lymph (water and solutes) from the lymphatic system, as well as chylomicrons or chyle, formed in the intestines from dietary fat and lipids, allowing these to enter the bloodstream; the products of fats and lipids can then be carried by the bloodstream to the hepatic ...
Subclavian steal syndrome (SSS), also called subclavian steal steno-occlusive disease, is a medical condition characterized by retrograde (reversed) blood flow in the vertebral artery or the internal thoracic artery. This reversal occurs due to proximal stenosis (narrowing) or occlusion of the subclavian artery.
The left subclavian artery supplies blood to the left arm and the right subclavian artery supplies blood to the right arm, with some branches supplying the head and thorax. On the left side of the body, the subclavian comes directly off the aortic arch , while on the right side it arises from the relatively short brachiocephalic artery when it ...
Besides, overuse injury of the upper limbs causes swellings, small bleeding, and subsequent fibrosis which would cause the thrombosis of the subclavian vein, leading to Paget–Schroetter disease or effort-induced thrombosis. [7] TOS can be related to cerebrovascular arterial insufficiency when affecting the subclavian artery. [8]
Aberrant subclavian artery, or aberrant subclavian artery syndrome, is a rare anatomical variant of the origin of the right or left subclavian artery. This abnormality is the most common congenital vascular anomaly of the aortic arch , [ 1 ] occurring in approximately 1% of individuals.
The brachiocephalic artery sends blood from the heart to the right arm, head, and neck. [8] Oxygenated blood from the aortic trunk is taken through the brachiocephalic artery into the right subclavian artery, which transports blood to the right arm, and into the right common carotid artery, where blood is transported to the head and neck. [9]
The right brachiocephalic vein is about 2.5cm long. [3] The right vein is formed by the confluence of the right subclavian vein and the right internal jugular vein. It receives the following tributaries: The right vertebral vein, the internal thoracic vein, and the thyroid veins, and occasionally from the first right posterior intercostal veins ...
[8] [9] In subclavian steal syndrome, blood is "stolen" from the vertebral artery on the affected side to preserve blood flow to the upper limb. Subclavian steal syndrome results from a proximal stenosis (narrowing) of the subclavian artery, one of arteries originating off of the aortic arch. Subclavian steal syndrome has potential to affect ...
