STERNOCLAVICULAR SEPTIC ARTHRITIS - A RARE BUT SERIOUS COMPLICATION OF SUBCLAVIAN VENOUS CATHETERIZATION

Sternoclavicular septic arthritis is a rare complication of subclavian venous catheterization. We estimate that septic involvement of this j oint may be as common as one in 500 catheterizations. We report two pa tients with insidious onset of shoulder pain, chest discomfort, low-gr ade fever and slight but painful swelling of a sternoclavicular joint four weeks following subclavian venous catheterization. Positive blood cultures in the presence of abnormal bone scan and abnormal conventio nal X-ray examination or computed tomography of the sternoclavicular j oint led to the diagnosis of septic arthritis. Both patients responded well to antibiotic treatment. Based on our observations and that repo rted in the literature, the earliest changes of sternoclavicular septi c arthritis may be detected by bone scan while plain X-ray studies and CT become abnormal during advanced stages of this type of arthritis. We would like to alert physicians to this cause of fever and joint pai n in patients who previously underwent subclavian venous catheterizati on.
