Vena cephalica

Vena Cephalica is a prominent vein of the upper limb and one of the two main superficial veins in the human body. It is also known as the cephalic vein.

Anatomy

The vena cephalica originates from the radial side of the dorsal venous network of the hand. It ascends in the lateral side of the forearm and arm in the subcutaneous tissue, superficial to the deep fascia. In the arm, it courses along the lateral border of the biceps muscle, and in the shoulder, it passes through the deltopectoral groove, between the deltoid muscle and the pectoralis major muscle. It then pierces the clavipectoral fascia and drains into the axillary vein.

Clinical Significance

The vena cephalica is often used for venipuncture (the collection of venous blood samples), and for the insertion of peripheral venous catheters and central venous catheters. Its superficial location and large diameter make it an accessible and safe site for these procedures. However, complications such as thrombophlebitis, infection, and injury to the surrounding structures can occur.
