| Popis: | The cephalic vein of the forearm is often used for IV catheters because of its ease of access for peripheral venous cannulation. But its close relation to the sensory branch of the radial nerve sometimes causes it to be damaged when the vein is cannulated. Our anatomic study conducted on 33 specimens confirmed the risk of nerve lesion. However, it is impossible to define a safe zone, because of the randomly located nerve and vein crossing zones, where the iatrogenic risk of damaging the radial nerve is maximum. We suggest that to avoid incidents, the cephalic vein should be punctured above the emergence of the sensory branch of the radial nerve, e.g., at least 12 cm above the level of the styloid process of the radius.We attempted to determine the relationship between the cephalic vein and the sensory branch of the radial nerve at the wrist to help prevent lesions of the radial nerve when the cephalic vein is cannulated. We examined the anatomy of 33 postmortem specimens and suggest that puncture of the cephalic vein 12 cm or more proximal to the styloid process can prevent radial nerve lesions. |
