Intermediate cephalic vein
The intermediate cephalic vein, also known as the median cephalic vein, is quite large and is located in the antecubital fossa, a good location for drawing blood. It is one of the forearm's main superficial veins and specifically branches off laterally from the intermediate antebrachial vein that connects to the cephalic vein close to the elbow. The intermediate cephalic vein joins with the intermediate antebrachial vein, the basilic vein, the cephalic vein, and the intermediate basilic vein to form an M-shaped antecubital vein pattern. Because the intermediate cephalic vein is easily accessible and located farther from major arteries and nerves than the other veins in the M-shaped vein complex, it is usually the second and safest choice for venipuncture in this vein structure. A puncture to this vein is also less painful than punctures to the other veins, and it does not have as great a chance of rolling. The intermediate cephalic vein can also be used in the cannularisation process.
