          Abstract

          Resumen La infección abdominal de una prótesis aórtica en pacientes portadores de bypass aórticos, aortoilíacos o aortofemorales unilaterales o bilaterales es una de las complicaciones más temibles que a nivel vascular podemos encontrar dada su alta morbilidad y, sobre todo, su alta mortalidad. Su manejo siempre va a ser difícil y acompañado por lo general de mal pronóstico, pues su tratamiento quirúrgico requiere una indicación, un estudio y una programación individualizados en cada paciente. Sea cual sea la actitud terapéutica inicial, conservadora o agresiva, la resolución final de la infección va a llevar aparejada la exéresis de la prótesis infectada y la revascularización de las extremidades inferiores mediante técnicas y materiales diversos. En cuanto a las técnicas a emplear podemos optar por el empleo de una vía ortoanatómica o extraanatómica y actuar en un tiempo o en dos. Entre los materiales a emplear tenemos los injertos autólogos con vena, como los de elección en caso de disponer de ellos, o de otros materiales alternativos en caso contrario, de los que encontramos publicado en la literatura el uso de una prótesis biosintética. Describimos nuestra experiencia en el manejo de estos pacientes mediante el empleo de la prótesis Omniflow II® por vía extraanatómica.

          Abstract Abdominal infection of an aortic prosthesis in patients with aortic, aortoiliac or aortofemoral bypass is one of the most feared vascular complications that we can find, because its high morbidity and, above all, its high mortality. Its handling is always going to be difficult and usually accompanied by poor prognosis because surgical treatment requires an indication, study and programming individualized for each patient. Whatever the initial therapeutic approach, conservative or aggressive, the final resolution of the infection will be accompanied by the excision of the infected prosthesis and revascularization of the lower limbs using different techniques and materials. As for the techniques employed, we can choose to use an ortho-anatomic or extra-anatomic reconstruction and to act in one or two times. Among the materials used we have the autologous venous grafts, as those of choice in case of having them, or alternative materials otherwise, of which are reported in the literature the use of a biosynthetic prosthesis. We describe our experience in the management of these patients by using the Omniflow II® prosthesis extraanatomically.

            A systematic review and meta-analysis of treatments for aortic graft infection.

            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. 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 ( 30 days) mortalities were determined for each treatment modality. Tests of heterogeneity and sensitivity analyses were performed. 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 .1 for all treatment outcomes across all modalities) and the limited variability of outcomes after sensitivity analyses. 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.

              Improved outcomes in the recent management of secondary aortoenteric fistula.

              We reviewed the presentation, management, and late events in a recent experience with aortic graft-enteric communications (secondary aortoenteric fistula) to identify variables associated with poor outcomes.
