[Infectious complications of implantable infusion ports in patients with HIV infection]

Thirty-four implantable ports were consecutively implanted in 27 AIDS patients (mean CD4 lymphocyte count: 39/mm3) from January 1993 to December 1995. We observed 33 complications in these patients. Perioperative complications included: one pneumothorax (3%), one haematothorax (3%) and one septic shock (3%). Later complications included one venous thrombosis (3%) and 26 infectious complications (79%). Fever of unknown origin was observed in three patients (9%). A total of 19 bacteremias occurred in 12 patients. The global rate of infection for 100 catheter-days was 0.51 for a total of 5,096 catheter-days. The following microorganisms were isolated: Staphylococcus (n = 21; 72%), Pseudomonas (n = 3; 11%) and others (n = 5; 17%). Thirty-eight percent of the ports (n = 13) were removed, after a mean of 89 days. During the study, 21 patients died. Two patients died from a catheter infection with septic shock (8%). It seems to be important to clearly define the indications of implantable infusions ports in AIDS patients with respect to their life expectancy.
