Sir, The cephalic vein of the forearm is often used for intravenous (i.v) cannulation because it is large, consistent and well‑splinted by bone. Although radial artery lies some distance away from the cephalic vein, accessory branches of the radial artery running close to the cephalic forearm vein have been described.[1,2] Venous cannulation at the lateral aspect of the wrist thus carries a small risk of arterial puncture if arterial anomalies are present.
