She noted these symptoms three weeks after phelebotomy. Electrodiagnostic study showed severe involvement of left side Medial Antebrachial Cutaneous nerve (MAC nerve).Phelebotomy is a cause of MAC nerve injury. Electrodiagnostic testing can be helpful in evaluating cases of sensory disturbance after phlebotomy.The MAC nerve can be damaged by a number of iatrgenic causes. Phlebotomy is a rare cause of injury.We present a case of phlebotomy-induced injury to the MAC nerve, in which the diagnosis was made using nerve conduction study. According to our knowledge, this is the first case in which electrodiagnostic studies were used to document venipuncture-related injury of the MAC nerve. The use of electrodiagnostic test for diagnosis of this type of injury, has only been reported one time for radial nerve and three for lateral antebrachial cutaneous nerve [1-4].A 45 year left-handed woman was referred to electromyography clinic for electrodiagnostic study because of hypoesthesia over the medial aspect of left forearm. She complained of a shooting pain along with the onset of dysesthesias over there. She noted this complaint since three weeks ago after routine venipuncture. The patient had no history of polyneuropathy, chronic systemic disease or surgical intervention at the elbow. Physical examination showed normal inspection and muscles power but decreased sensation of pinprick and light touch in anteromedial aspect of forearm. Electrodiagnostic study was performed on bilateral MAC nerves using routine technique [5]. The study revealed absence of sensory nerve action potential from the left MAC nerve, and normal in right side [Figure 1].For confirmation the diagnosis, we tried several times with stimulation in various points in cubital fossa and with high stimulation current up to 45 mA. All other nerves in left upper limb were normal in nerve condu %U http://www.jbppni.com/content/6/1/5
