I examined 11 patients with upper-extremity causalgia secondary to peripheral nerve injury occurring during routine venipuncture.The nerves affected were the medial(n=5)and lateral(n=2)antebrachial cutaneous in the antecubitus fossa,the superficial radial at the wrist(n=2),and the dorsal sensory branches in the hand(n=2).Anatomically,nerves lie on a plane just beneath and in close proximity to veins,making them vulnerable to injury during the procedure. |
