Yellow circle indicates the left venous angle. The venous angle (also known as Pirogoff's angle and in Latin as angulus venosus) is the junction where the ipsilateral internal jugular vein and subclavian vein unite to form the ipsilateral brachiocephalic vein. [1] [2] The thoracic duct drains at the left venous angle, and the right lymphatic ...
In over 95% of individuals, the thoracic duct ends by draining either at the venous angle, or into the internal jugular vein, or the subclavian vein, but - in the minority of cases - empties into either the brachiocephalic vein, external jugular vein, suprascapular vein, transverse cervical vein, or vertebral vein.

The Pirogov triangle (also Piragoff's triangle) is an area in the human neck formed by the intermediate tendon of the digastric muscle, the posterior border of the mylohyoid muscle, and the hypoglossal nerve.
In the mediastinal lymph nodes arises lymphatic ducts, which drains the lymph to the left subclavian vein (to the venous angle in the confluence of the subclavian and deep jugular veins). The mediastinal lymph nodes along the esophagus are in tight connection with the abdominal lymph nodes along the esophagus and the stomach. That fact ...

These trunks act as major conduits for lymph to reach larger lymphatic ducts or directly enter the venous circulation at the venous angle. [ 2 ] [ 3 ] This transportation process is vital for immune surveillance, as it enables the movement of lymphocytes and antigen-presenting cells to lymph nodes where they can detect and respond to pathogens ...
The Trendelenburg position is also used when placing a central venous catheter in the internal jugular or subclavian vein. The Trendelenburg position uses gravity to assist in the filling and distension of the upper central veins, as well as the external jugular vein. It plays no role in the placement of a femoral central venous catheter. [7]
The septal veins drain blood from the septum pellucidum bilaterally [2] and terminate at the venous angle formed with the thalamostriate veins. [4] Research by Jonathan Roth et al., 2010, has shown that the septal veins are often asymmetrical. [5]
