thoracic duct การใช้

• On the left side it joins the thoracic duct.
• The thoracic duct empties the chylomicrons into the bloodstream via the left subclavian vein.
• *In 2004 he identified a new disease : The intermittent obstruction of the thoracic duct end.
• There are two lymph ducts in the body & mdash; the right lymphatic duct and the thoracic duct.
• Free lymphocytes constantly recirculate in blood after their re-entry from lymphoid tissue, via lymphatic and thoracic ducts.
• To the right is the azygos veins and thoracic duct, and to the left is the left pleura and lung.
• In adults, the thoracic duct is typically 38 45 cm in length and has an average diameter of about 5 mm.
• Another concept is that one of the supraclavicular nodes corresponds to the end node along the thoracic duct and hence the enlargement.
• In animals, the most effective form of treatment until recently has been surgical ligation of the thoracic duct combined with partial pericardectomy.
• The thoracic duct drains lymph into the circulatory system at the left brachiocephalic vein between the left subclavian and left internal jugular veins.
• As they circulate through the lymphatic vessels, nascent chylomicrons bypass the liver circulation and are drained via the thoracic duct into the bloodstream.
• This fibrous arch forms the anterior aspect of the aortic hiatus, through which the aorta, thoracic duct, and azygos vein pass.
• If chylous leakage or accumulations persist despite treatment, imaging with heavy T2 weighted MRI, MRI lymphangiography or thoracic duct lymphangiography can be considered.
• On the left side, this trunk drains into the thoracic duct; on the right side, it drains into the right lymphatic duct.
• Each jugular lymph sac retains at least one connection with its jugular vein, the left one developing into the superior portion of the thoracic duct.
• Cannulation of the thoracic duct followed by embolization should be considered in those patients who are shown to have leakage of lymphatic fluid into the airway.
• It is transported via the lymphatic system and the thoracic duct up to a location near the heart ( where the arteries and veins are larger ).
• The lacteals merge to form larger lymphatic vessels that transport the chyle to the thoracic duct where it is emptied into the bloodstream at the subclavian vein.
• The lymphatic system drains the head and neck of excess interstitial fluid via lymph vessels or capillaries, equally into the right lymphatic duct and the thoracic duct.
• Lymph from these deep nodes passes to the jugular lymphatic trunk, which joins the thoracic duct on the left side and the brachiocephalic vein on the right side.
