ABSTRACT
A patient with spina bifida secondary to an Arnold-Chiari deformity experienced seven episodes of sustained bacteremia due to Staphylococcus aureus over 2 years. Despite an extensive diagnostic evaluation the source of the recurrent bacteremia remained obscure. The patient's mother eventually recalled that a procedure for replacement of a ventriculoatrial shunt performed 16 years earlier had been complicated by retention of a shunt fragment in the bloodstream. Standard radiographic techniques failed to identify an intravascular foreign body; however, ultrafast computerized tomography of the heart demonstrated a density in the right atrium. Atriotomy was performed and a plastic catheter fragment was excised. Bacteremia has not recurred during a follow-up period of 24 months. Patients with recurrent unexplained bacteremia should be evaluated carefully for the presence of occult intravascular catheter fragments that may be retained after surgical procedures or intravascular instrumentation. Ultrafast computed tomographic scanning of the heart is a useful technique for detecting intracardiac catheter fragments.
