Pulmonary fiber embolism and granuloma

T. T. Tang, C. H. Chambers, W. J. Gallen and S. R. McCreadie

Three infants had pulmonary fiber embolism and granuloma following cardiac catheterization. These complications were traced to the use of nondisposable woven synthetic fiber catheters. The fibrous linings of the catheter may fray and break, and the debris may become disseminated during angiography to the lungs to form emboli and intravascular and extravascular granulomas.
