The incidence and factors associated with graft infection after aortic aneurysm repair.

摘要: Objectives The reported rate of abdominal aortic graft infections (AGIs) is low, but its incidence and associated factors have not been evaluated on a population level. We hypothesized that AGI occurs more often in patients with periprocedural nosocomial less after endovascular aneurysm repair (EVAR). Methods A retrospective cohort study was done all undergoing (AAA) (1987-2005) Washington State by using the Comprehensive Hospital Abstract Reporting System (CHARS) data. Nosocomial infection defined as one or pneumonia, urinary tract infections, blood stream septicemia, surgical site at index admission. Readmissions reintervention for AGIs excluding diagnostic code renal failure those who appeared to dialysis grafts. Results Between 1987 2005, 13,902 (mean age, 71.3 ± 8.8 years; 90.8% men) underwent AAA (12,626 open, 1276 EVAR). cumulative 0.44%. 2-year 0.19% among open vs 0.16% EVAR ( P = .75) 0.2% both elective nonelective patients. Open procedures had greater rates perioperative pneumonia (11.1% 2.4%, .014) (1.61% 0.19%, .01) were significantly AGIs. median time 3.0 years, presented sooner (≤1.4 years) if occurred This risk developing highest first postoperative year (32% 1). In an adjusted model, septicemia (odds ratio, 4.2; 95% confidence interval, 1.5-11.8) Conclusions most commonly year, similar EAVR. Patients earlier onset AGI. higher hospitalization. These data may be helpful directing surveillance programs AIG.
