Abstract

Being familiar with anatomical variations is necessary for surgeons and radio-interventionists. Arterial variations are important for interventional cardiologist and a potential danger is vasoconstriction and acute ischemia [1]. Venous variations are important in Intravenous (IV) lines and catheterizations. Embryological basis of vascular variations is unknown. Evidence does not support its genetic basis and it seems to be due to intrauterine events during distal end deviation of vessels [1-2]. Cephalic vein is a superficial vein of upper limb drained to the proximal end of axillary vein. Cephalic vein lies in deltopectoral groove and goes through infraclavicular fossa.Axillary and cephalic veins are integrated and create subclavian vein. Subclavian vein in turn drains to brachiocephalic trunk and then Superior Vena Cava (SVC) [3]. Different clinical applications are considered for cephalic vein. For instance, cephalic vein catheterization can be pointed out. It can be used for IV injections as well as volume resuscitation as an alternative for central venous catheterization in emergent conditions
