          Abstract

          Resumen Introducción: la infección de prótesis después de cirugía abierta de aorta abdominal es infrecuente (0,7-3 %) y potencialmente mortal. El manejo clásico ha sido mediante revascularización extraanatómica y retiro del material protésico, y actualmente existen alternativas de reparación in situ. La mortalidad perioperatoria global es entre 4 y 40 % dependiendo de la serie y del tipo de reparación. Objetivos: reportar nuestra experiencia con revascularización extraanatómica y resección de la prótesis infectada. Metodología: estudio retrospectivo entre 1977 y 2020. Se incluyeron solo pacientes con infección de prótesis tratados mediante resección y reconstrucción extraanatómica. Se consideraron variables demográficas, comorbilidades, presentación clínica y agente microbiano. Como resultado primario utilizamos mortalidad posoperatoria y para resultados secundarios: reoperaciones, complicaciones precoces y tardías, amputación mayor, permeabilidad y sobrevida alejada. Se realizaron estadísticas descriptivas y asociaciones dicotómicas con chi-cuadrado. Resultados: dieciséis pacientes, todos masculinos. Edad promedio 69,2 años (55-82). Tiempo promedio de cirugía a infección de 27,8 meses (1-84). Fue más frecuente la infección en pacientes intervenidos por aneurisma roto que por otras causas (p < 0,05). Once pacientes (68,8 %) presentaban fiebre, 6 (37,5 %) debutaron con dolor abdominal o lumbar, 5 (31,3 %) con signos inflamatorios cutáneos (región inguinal o lumbar). Doce pacientes (75 %) presentaron comunicación aortoduodenal: 6 fístulas y 6 erosiones. Tres pacientes (18,8 %) debutaron con isquemia de miembros inferiores. Siete pacientes (43,8 %) presentaron complicaciones posoperatorias mayores y 2 pacientes fallecieron en el posoperatorio (12,5 %). La sobrevida actuarial al año y a 5 años fue de 86,7 % y 64,3 % respectivamente. Las permeabilidades primaria y secundaria de la reconstrucción extraanatómica a 5 años fue 77,8 % y 100 %, respectivamente. Conclusiones: la infección de prótesis aórtica es una entidad grave, cuyo tratamiento conlleva una morbimortalidad significativa. La revascularización extraanatómica y resección de prótesis infectada continúa siendo una alternativa de manejo y permite solucionar de forma segura y efectiva el foco séptico.

          Abstract Introduction: aortic graft infection (AGI) after aortic open repair is an unusual (0.7-3 %) and potentially lethal complication. Standard treatment has been excision of infected graft and extra anatomic bypass, although currently there are in situ repair techniques. Global perioperative mortality is 4-40 % according to the series and the repair technique. Objectives: to report our experience with extra anatomic revascularization and excision of infected graft in AGI. Methodology: retrospective study between 1977 and 2020. Were included patients with AGI treated with extra anatomic revascularization and excision of infected graft only. Demographics, morbidities, clinical presentation and microbiological agents were considered. Primary outcome was postoperative mortality. Secondary outcomes were reinterventions, postoperative complications, major amputations, bypass patency and long-term survival. Descriptive statistics were performed and dycotomical asociations were established with chi-squared test. Results: sixteen patients, all male. Average age 69.2 years (55-82). Average time to infection from surgery was 27.8 months (1-84). AGI was more frequent in patients with ruptured aortic aneurysm (p < 0.05). Eleven patients (68.8 %) had fever, 6 (37.5 %) consulted with abdominal or lumbar pain, 5 (31.3 %) had inflammatory changes of local skin. Twelve patients (75 %) had aortoduodenal communications. Three patients (18.8 %) had lower limb ischemia. Seven patients (43.8 %) presented postoperative complications and 2 patients expired (12.5 %). Actuarial one-year and five-year survival were 86.7 % and 64.3 %, respectively. Five-year primary and secondary patency of the axillofemoral bypass were 77.8 % and 100 %, respectively. Conclusions: AGI is a serious condition, which treatment carries significant morbidity and mortality. Axillofemoral bypass grafting and infected graft excision currently is a safe alternative of treatment.

          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.

            Long-term results of the treatment of aortic graft infection by in situ replacement with femoral popliteal vein grafts.

            Graft excision and neo-aortoiliac system (NAIS) reconstruction with large caliber, femoral popliteal vein (FPV) grafts have been reported as successful treatment of aortic graft infection (AGI) in several small series with limited follow-up. The goal of this study was to evaluate long-term outcomes in large cohort of consecutive patients treated with NAIS for AGI.

              Allograft replacement for infrarenal aortic graft infection: early and late results in 179 patients.

              We evaluated early and late results of allograft replacement to treat infrarenal aortic graft infection in a large number of patients and compared the results in patients who received fresh allografts versus patients who received cryopreserved allografts. From 1988 to 2002 we operated on 179 consecutive patients (mean age, 64.6 +/- 9.0 years; 88.8% men). One hundred twenty-five patients (69.8%) had primary graft infections, and 54 patients (30.2%) had secondary aortoenteric fistulas (AEFs). Fresh allografts were used in 111 patients (62.0%) until 1996, and cryopreserved allografts were used in 68 patients (38.0%) thereafter. Early postoperative mortality was 20.1% (36 patients), including four (2.2%) allograft-related deaths from rupture of the allograft (recurrent AEF, n = 3), all in patients with fresh allografts. Thirty-two deaths were not allograft related. Significant risk factors for early mortality were septic shock (P <.001), presence of AEF (P =.04), emergency operation (P =.003), emergency allograft replacement (P =.0075), surgical complication (P =.003) or medical complication (P <.0001), and need for repeat operation (P =.04). There were five (2.8%) nonlethal allograft complications (rupture, n = 2; thromboses, which were successfully treated at repeat operation, n = 2; and amputation, n = 1), all in patients with fresh allografts. Four patients (2.2%) were lost to follow-up. Mean follow-up was 46.0 +/- 42.1 months (range, 1-148 months). Late mortality was 25.9% (37 patients). There were three (2.1%) allograft-related late deaths from rupture of the allograft, at 9, 10, and 27 months, respectively, all in patients with fresh allografts. Actuarial survival was 73.2% +/- 6.8% at 1 year, 55.0% +/- 8.8% at 5 years, and 49.4% +/- 9.6% at 7 years. Late nonlethal aortic events occurred in 10 patients (7.2%; occlusion, n = 4; dilatation < 4 cm, n = 5; aneurysm, n = 1), at a mean of 28.3 +/- 28.2 months, all but two in patients with fresh allografts. The only significant risk factor for late aortic events was use of an allograft obtained from the descending thoracic aorta (P =.03). Actuarial freedom from late aortic events was 96.6% +/- 3.4% at 1 year, 89.3% +/- 6.6% at 3 years, and 89.3% +/- 6.6% at 5 years. There were 63 late, mostly occlusive, iliofemoral events, which occurred at a mean of 34.9 +/- 33.7 months in 38 patients (26.6%), 28 of whom (73.7%) had received fresh allografts. The only significant risk factor for late iliofemoral events was use of fresh allografts versus cryopreserved allografts (P =.03). Actuarial freedom from late iliofemoral events was 84.6% +/- 7.0% at 1 year, 72.5% +/- 9.0% at 3 years, and 66.4% +/- 10.2% at 5 years. Early and long-term results of allograft replacement are at least similar to those of other methods to manage infrarenal aortic graft infections. Rare specific complications include early or late allograft rupture and late aortic dilatation. The more frequent late iliofemoral complications may be easily managed through the groin. These complications are significantly reduced by using cryopreserved allografts rather than fresh allografts and by not using allografts obtained from the descending thoracic aorta.
