[Puncture of the radial vein: a forgotten complication].

The superficial radial vein at the lateral edge of the inferior third of the forearm and of the wrist has strong anatomical relationship with the sensory superficial branch of the radial nerve. At this level, any venous puncture may be responsible for a lesion of this superficial part of the radial nerve. We report two cases of dysesthesia in the radial territory after this kind of puncture. This risk should not be neglected and venous puncture should be avoided in this area.
