Saline-filled breast implant contamination with Curvularia species among women who underwent cosmetic breast augmentation

Abstract

Background. During December 2000-July 2001, black sediment was noted in saline-filled silicone breast implants of women who had undergone revision surgery at facility A. Curvularia fungus was isolated from implant saline. Methods. To identify risk factors for contamination with Curvularia species, we performed case-control, retrospective cohort, and laboratory studies and conducted procedural reviews. A case patient was defined as any woman who underwent revision surgery at facility A between January 2000 and June 2001 and had black sediment in her implants. Results. Five patients met the case definition. Contamination was associated with having had surgery performed in operating room (OR) 2 (4/88 vs. 1/140; P = .07) and a longer duration of surgery (P < .001). Saline was warmed in a cabinet opposite OR 2, which was maintained at negative pressure differentials, then was poured into bowls open to the OR 2 environment before injection into implants. Conclusion. Surgeons should always use closed systems to inflate breast implants. Surgery center infection control measures must include moisture control and balanced ventilation systems. © 2005 by the Infectious Diseases Society of America. All rights reserved.
