The main mechanism of chylothorax is the leaking of chyle from the thoracic duct, usually caused by a disturbance affecting the structural integrity of the thoracic duct. [5] For example, placement of a central venous catheter can potentially disrupt drainage of lymph into the subclavian veins , followed by the thoracic duct, resulting in ...
A bifid inferior portion of the thoracic duct (due to a failure of fusion during embryonic development) is not uncommonly observed; a plexus of lymphatic vessels replacing the thoracic duct inferiorly and only coalescing into a single duct in the mediastinum may also occur. Rarely, the thoracic duct may be entirely bilaterally paired. [3 ...
A chyle fistula occurs when defect(s) of lymphatic vessel(s) result in leakage of lymphatic fluid, typically accumulating in the thoracic (pleural) or abdominal (peritoneal) cavities, [2] leading to a chylous pleural effusion (chylothorax) or chylous ascites, respectively.
The right lymphatic duct drains the right side of the region and the much larger left lymphatic duct, known as the thoracic duct, drains the left side of the body. The ducts empty into the subclavian veins to return to the blood circulation. Lymph is moved through the system by muscle contractions. [9]
In humans, the cisterna chyli is located posterior to the abdominal aorta on the anterior aspect of the bodies of the first and second lumbar vertebrae (L1 and L2). There it forms the beginning of the primary lymph vessel, the thoracic duct, which transports lymph and chyle from the abdomen via the aortic opening of the diaphragm up to the junction of left subclavian vein and internal jugular ...
[6] Chylothorax results as a rare complication in which chyle leaks into the thoracic space following direct incidental damage and can also lead to increased thoracic duct pressure. [6] Chylothorax leakage commonly occurs in patients with additional complex congenital heart lesions, increasing the risk of underlying vascular anomalies.
A Minnesota couple has reportedly been sentenced to four years after they locked their children in cages for "their safety." The couple was arrested and charged with 16 counts in June 2023. They ...
