Peripheral vein cannulation is one of the commonest procedure performed in the emergency department and the veins of the forearm are the most commonly cannulated vessels. Although the aberrant course of an artery in the forearm is reported in the literature by as high as 1% of the general population, they are not given due importance during vessel cannulation. Inadvertent arterial cannulation and administration of the drug can have serious short-term and long-term consequences. This case report is about two such cases of unintentional intra-arterial cannulation of an aberrant radial artery which was confirmed with the help of a bedside ultrasound performed by the emergency physician. This case report reminds us that peripheral vein cannulation must always be done considering the possibility of an aberrant course of arteries in the forearm and performing a bedside screening ultrasound scan in the forearm can be a useful tool to prevent inadvertent intra-arterial cannulation.
