Complex regional pain syndrome is a neuropathic pain disorder, which causes pain, edema, limited range of motion, skin temperature variation, and skin color variation in the affected part. In this paper, experimental findings of complex regional pain syndrome in a patient, who had an arteriovenous shunt operation on his forearm in the past, are discussed. The patient’s illness was diagnosed through physical examination, thermographic inspection, and three-phase bone scintigraphy. He had symptoms of vasodilation in his brachium and forearm. Also, diffuse uptake condition in his affected area was observed in a delayed image, perfusion phase and hepatic blood pool images through three-phase bone scintigraphy. Moreover, body temperature of his hand and forearm on the affected side rose by 3.02~5.57。. Nevertheless, the cause is unknown in 10~23% of complex regional pain syndrome. Therefore, all possible cases of complex regional pain syndrome cannot be completely ruled out, and it should be treated early by performing thorough history taking, radio-graphic inspection, three-phase bone scintigraphy, thermographic inspection, and electromyography as well as active physical examination. |
