lüll A systematic review and meta-analysis of treatments for aortic graft infection O'Connor S; Andrew P; Batt M; Becquemin JPJ Vasc Surg 2006[Jul]; 44 (1): 38-45OBJECTIVE: We compared pooled estimates of event rates for amputations, conduit failures, reinfections, early mortalities, and late mortalities in patients with aortic graft infection who were treated by extra-anatomic bypass, rifampicin-bonded prostheses, cryopreserved allografts, or autogenous veins. METHODS: A systematic review was conducted of English language reports in MEDLINE back to 1985 and a meta-analysis was performed on the results. Studies were selected on the basis of medical subject headings aortic, graft, and infection, and also by a standardized and independent quality rating. Inclusion and exclusion criteria were met by 37 clinical studies. Pooled estimates of mean event rates for amputations, conduit failures, reinfections, early (< or =30 day) mortalities, and late (>30 days) mortalities were determined for each treatment modality. Tests of heterogeneity and sensitivity analyses were performed. RESULTS: Fixed effect analyses, derived after tests of heterogeneity, yielded overall pooled estimates of mean event rates for all outcomes combined of 0.16 for extra-anatomic bypass, 0.07 for rifampicin-bonded prostheses, 0.09 for cryopreserved allografts, and 0.10 for autogenous vein; a lower value signifies fewer overall events associated with the treatment modality. Overall, the robustness of our meta-analysis was demonstrated by the reasonable heterogeneity of pooled data from individual studies (Q statistic <25; P >.1 for all treatment outcomes across all modalities) and the limited variability of outcomes after sensitivity analyses. CONCLUSION: Although limited by the design of individual published studies whose data were pooled together in this meta-analysis, our results lead to questions concerning whether extra-anatomic bypass should remain the gold standard for treatment of aortic graft infection.|Antibiotics, Antitubercular/administration & dosage[MESH]|Aortic Diseases/mortality/*surgery[MESH]|Blood Vessel Prosthesis/*adverse effects[MESH]|Blood Vessels/*transplantation[MESH]|Cryopreservation[MESH]|Humans[MESH]|Prosthesis-Related Infections/mortality/*surgery[MESH]|Rifampin/administration & dosage[MESH]|Transplantation, Autologous[MESH]|Treatment Outcome[MESH] |
