The axillary vein is a large vein that drains blood from the upper limb, continuing from the basilic vein at the lower border of the teres major muscle. It becomes the subclavian vein at the lateral border of the first rib. During a subclavian vein puncture, the needle is often inserted below the clavicle (collarbone) and directed towards the junction of the subclavian vein and the internal jugular vein. The axillary vein is relevant because it is a direct continuation of the subclavian vein. When attempting to access the subclavian vein, the needle may inadvertently enter the distal part of the subclavian vein, which is anatomically continuous with the axillary vein. Therefore, understanding the anatomy of the axillary vein helps in accurately locating and cannulating the subclavian vein and avoiding complications.
