Accessory cephalic vein
Accessory Cephalic Vein
The Accessory Cephalic Vein (pronunciation: ak-ses-uh-ree sef-uh-lik vein) is a superficial vein of the upper limb. It is a variant of the cephalic vein, one of the main superficial veins of the arm.
Etymology
The term "Accessory Cephalic Vein" is derived from the Latin words 'accessorius' meaning additional, and 'cephalicus' meaning of the head. The term 'vein' is derived from the Latin word 'vena', which means blood vessel.
Anatomy
The Accessory Cephalic Vein typically arises from a venous network on the radial side of the dorsum of the hand and forearm. It ascends in the forearm, passes over the lateral side of the wrist, and up the lateral side of the forearm and arm. It then usually drains into the cephalic vein proximal to the elbow.
Clinical Significance
The Accessory Cephalic Vein is often used for venipuncture (the process of obtaining intravenous access for the purpose of intravenous therapy or for blood sampling). Its superficial location makes it an accessible vessel for this procedure.
