As the subclavian artery crosses the lateral border of the first rib, it becomes the axillary artery. [1] [2] On the right side, the subclavian artery arises from the brachiocephalic (innominate) artery behind the right sternoclavicular articulation; on the left side it springs from the arch of the aorta.
The subclavian artery can be inadvertently punctured while attempting a subclavian vein access, leading to a subcutaneous hematoma and occasionally a pseudoaneurysm. An alternative site may need to be used for port placement.
Surgically implanted infusion ports are placed below the clavicle (infraclavicular fossa), with the catheter threaded into the heart (right atrium) through a large vein. Once implanted, the port is accessed via a "gripper" non-coring Huber-tipped needle (PowerLoc is one brand, common sizes are 0.75 and 1 inch (19 and 25 mm) length; 19 and 20 gauge.
Dysphagia lusoria (or Bayford-Autenrieth dysphagia) is an abnormal condition characterized by difficulty in swallowing caused by an aberrant right subclavian artery. It was discovered by David Bayford in 1761 and first reported in a paper by the same in 1787. [1]
The procedure involves connecting a branch of the subclavian artery or carotid artery to the pulmonary artery. In modern practice, this procedure is temporarily used to direct blood flow to the lungs and relieve cyanosis while the infant is waiting for corrective or definitive surgery when their heart is larger.
In the innominate artery, the average reading is 110/70 mmHg, the right subclavian artery averages 120/80 and the abdominal aorta is 110/70 mmHg. [25] The relatively uniform pressure in the arteries indicate that these blood vessels act as a pressure reservoir for fluids that are transported within them.
As the subclavian vein is large, central and relatively superficial, the right subclavian vein is often used to place central venous lines. [4] [5] It is less commonly used than other approaches, such as the right internal jugular vein, due to the risk of pneumothorax, haemothorax, and puncture of the accompanying subclavian artery.
