A peripherally inserted central catheter, or PICC line (pronounced "pick"), is a central venous catheter inserted into a vein in the arm (via the basilic or cephalic veins) rather than a vein in the neck or chest. The basilic vein is usually a better target for cannulation than the cephalic vein because it is larger and runs a straighter course ...
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 ...
During subclavian vein central line placement, the catheter can be accidentally pushed into the internal jugular vein on the same side instead of the superior vena cava. A chest x-ray is performed after insertion to rule out this possibility.
Catheter placement in one of the big veins (Subclavian vein, Internal jugular vein or femoral vein) is routinely done to monitor central venous pressure (CVP), to administer long term intravenous medication and parenteral nutrition in critically sick patients. The subclavian vein is the preferred choice for this purpose because it is most ...
The left bronchomediastinal lymph trunk often empties into the thoracic duct or directly into the venous angle, where the internal jugular and subclavian veins converge. Similarly, the right trunk may connect to the right lymphatic duct or end at the right venous angle . [ 2 ]
The first sign of a malignancy, especially an intra-abdominal one, may be an enlarged Virchow's node, a lymph node in the left supraclavicular area, in the vicinity where the thoracic duct empties into the left brachiocephalic vein, right between where the left subclavian vein and left internal jugular join (i.e., the left Pirogoff angle).
First described in 1975, [2] it is an alternative to central venous catheters in major veins such as the subclavian vein, the internal jugular vein or the femoral vein. Subclavian and jugular line placements may result in pneumothorax (air in the pleural space of lung), while PICC lines have no such issue because of the method of placement.
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 ...
