			The '''venous angle''', also known as the '''Pirogoff angle''', is a critical anatomical structure in the human [[circulatory system]]. It is the junction where the [[internal jugular vein]] and the [[subclavian vein]] converge to form the [[brachiocephalic vein]]. This angle is located at the root of the neck, near the [[clavicle]].

			The venous angle is situated bilaterally, meaning there is one on each side of the body. The right and left venous angles are formed by the union of the respective internal jugular and subclavian veins. The right venous angle is typically more prominent due to the direct drainage of the [[lymphatic system]] into the venous circulation at this point.

	The venous angle is situated bilaterally, meaning there is one on each side of the body. Each venous angle is formed by the union of the subclavian vein, which drains blood from the upper limb, and the internal jugular vein, which drains blood from the brain, face, and neck. The left venous angle is particularly significant because it is the site where the [[~~thoracic~~ duct]] ~~empties~~ lymph into the ~~venous circulation~~. On the right side, the [[right ~~lymphatic duct]] drains into~~ the ~~venous angle~~.		===Right Venous Angle===
			The right venous angle is particularly significant because it is the site where the [[right lymphatic duct]] drains lymph from the right upper quadrant of the body into the bloodstream. This includes lymph from the right arm, right side of the thorax, and the right halves of the head and neck.

	=== Left Venous Angle ===		===Left Venous Angle===
			The left venous angle is where the [[thoracic duct]], the largest lymphatic vessel in the body, empties lymph into the venous system. The thoracic duct collects lymph from the rest of the body, including the lower limbs, abdomen, left thorax, left arm, and left side of the head and neck.

	The left venous angle is located at the junction of the left subclavian vein and the left internal jugular vein. It is an important site for the drainage of lymphatic fluid from the thoracic duct, which collects lymph from the majority of the body, including the lower limbs, abdomen, left thorax, left upper limb, and left side of the head and neck.		==Clinical Significance==
			The venous angles are clinically important for several reasons. They are common sites for the insertion of [[central venous catheters]], which are used for administering medications, fluids, and for measuring central venous pressure. The proximity of the venous angles to major lymphatic ducts also makes them key sites for understanding lymphatic drainage and potential sites for lymphatic obstruction or injury.
	~~=== Right Venous Angle ===~~

	The right venous angle is formed by the right subclavian vein and the right internal jugular vein. The right lymphatic duct, which drains lymph from the right upper limb, right thorax, and right side of the head and neck, empties into this angle.

	== Clinical Significance ==

	The venous angles are clinically ~~significant~~ for several reasons. They are common sites for the insertion of central venous catheters, which are used for administering medications, fluids, and for measuring central venous pressure. The proximity of the ~~thoracic duct~~ to ~~the left venous angle~~ makes ~~it a~~ potential ~~site~~ for ~~complications such as chylothorax if the duct is inadvertently damaged during medical procedures~~.

== Venous Angle ==

[[File:Venenwinkel.png|thumb|Diagram showing the venous angle, where the subclavian vein and internal jugular vein meet.]]

The '''venous angle''', also known as the '''Pirogoff's angle''', is a critical anatomical structure in the human body where the [[subclavian vein]] and the [[internal jugular vein]] converge to form the [[brachiocephalic vein]]. This junction is located at the root of the neck, near the clavicle, and plays a vital role in the venous return from the head, neck, and upper limbs to the heart.

== Anatomy ==

The venous angle is situated bilaterally, meaning there is one on each side of the body. Each venous angle is formed by the union of the subclavian vein, which drains blood from the upper limb, and the internal jugular vein, which drains blood from the brain, face, and neck. The left venous angle is particularly significant because it is the site where the [[thoracic duct]] empties lymph into the venous circulation. On the right side, the [[right lymphatic duct]] drains into the venous angle.

=== Left Venous Angle ===

The left venous angle is located at the junction of the left subclavian vein and the left internal jugular vein. It is an important site for the drainage of lymphatic fluid from the thoracic duct, which collects lymph from the majority of the body, including the lower limbs, abdomen, left thorax, left upper limb, and left side of the head and neck.

=== Right Venous Angle ===

The right venous angle is formed by the right subclavian vein and the right internal jugular vein. The right lymphatic duct, which drains lymph from the right upper limb, right thorax, and right side of the head and neck, empties into this angle.

== Clinical Significance ==

The venous angles are clinically significant for several reasons. They are common sites for the insertion of central venous catheters, which are used for administering medications, fluids, and for measuring central venous pressure. The proximity of the thoracic duct to the left venous angle makes it a potential site for complications such as chylothorax if the duct is inadvertently damaged during medical procedures.
