Lateral Internal Thoracic Artery

Version 1

Abstract

The internal thoracic may give rise to a lateral internal thoracic as it enters the thorax. The lateral internal thoracic runs about midway between the spine and the sternum or somewhat forward, spans up to six intercostal spaces, and anastomoses with the intercostal arteries of those spaces. A lateral internal thoracic artery may arise from the costocervical trunk, thyrocervical trunk, or ascending cervical. The possible existence of this vessel must be remembered when paracentesis is performed.

The possible existence of this vessel must be remembered when paracentesis is performed.

Accessory internal thoracic vessels have been reported, which may give rise to superficial or deep cervical branches. Accessory internal thoracic arteries were found in 1.6% of 60 cadavers by Nathan, et al.
