[Infection of polytetrafluorethylene prosthesis in modified Blalock-Taussig anastomosis].
A 16 month-old baby submitted to systemic-pulmonary shunt with a polytetrafluorethylene prosthesis, who presented hyperthermia, radiologic signs of pulmonary opacifications and positive culture for staphylococcus aureus. Reoperation disclosed a prosthesis pseudoaneurysm, with disconnection of the anastomosis and evidences of infection. This complication has a low diagnostic rate and a high mortality and should always be suspected when signs of systemic infection become apparent in the postoperative period of polytetrafluorethylene systemic-pulmonary shunt.
