          Abstract

          Resumen Introducción: la presentación clínica más frecuente de infección protésica aórtica, secundaria a una fístula aortoentérica (FAE) es la hemorragia gastrointestinal. Se presenta un caso de debut atípico de infección protésica en un paciente con un absceso glúteo y sepsis que la demuestra en estudio complementario. Caso clínico: se trata de un paciente de 69 años, con antecedentes de bypass femoropoplíteo a 1.ª porción en ambas extremidades inferiores y de bypass aortobifemoral (2017). Ante el hallazgo de infección protésica, fue intervenido de un explante de la prótesis aortobifemoral por laparotomía transversa y drenaje de absceso de psoas derecho. Se observó fístula a nivel de tercera porción duodenal distal, no observada en la gastroscopia preoperatoria, que se reparó con sutura primaria y patch yeyunal. Se tomaron cultivos de absceso glúteo, observando Candida krusei y Brevibacterium ravenspurgense, pautando antibioterapia intravenosa en el posoperatorio. En los días posteriores se intervino de una amputación supracondílea de pierna derecha por empeoramiento de la isquemia en dicha extremidad. Discusión: la FAE es una complicación rara y potencialmente mortal de la reparación del aneurisma aórtico abdominal. A pesar de no existir ensayos controlados para estandarizar el manejo, la mejor terapia sigue siendo la explantación completa del injerto con reemplazo por material autólogo o reconstrucción extraanatómica.

          Abstract Introduction: gastrointestinal bleeding is the most frequent clinical debut of aortic graft infections, secondary to an aortoenteric fistula (AEF). We show a case of an atypical debut of prosthetic infection as an incidental finding in image, requested by gluteal abscess and sepsis. Case report: a 69-year-old patient, with a medical record of femoropopliteal bypass at 1st portion in both lower extremities and aortobifemoral bypass (2017). When finding the graft infection, he was operated for an extraction of aortobifemoral graft by transverse laparotomy and drainage of right psoas abscess. A fistula was not noticed in preoperative gastroscopy seen at the level of the 3rd distal portion and repaired with a primary suture and jejunal patch. Gluteal abscess samples were taken, showing Candida krusei and Brevibacterium ravenspurgense. Intravenous antibiotic therapy was prescribed in the postoperative period. In the following days, he underwent a supracondylar amputation of the right leg due to worsening of the ischemia in said limb. Discussion: AEF is a rare and life-threatening complication of abdominal aortic aneurysm repair. Despite the absence of controlled trials to standardize the management, the best therapy remains the complete graft explantation with replacement by autologous material or extraanatomic reconstruction.

          Diverse Presentation of Secondary Aortoenteric Fistulae

          Secondary aortoenteric fistula, due to mechanical erosion or infection of a prosthetic graft, is a very rare cause of gastrointestinal bleeding and an uncommon complication of abdominal aortic aneurysm repair. A retrospective chart review conducted at our institution revealed 5 cases of secondary AEF occurring between 2006 and 2010. Presentations were diverse, including hematemesis, coffee-ground emesis, and unexplained sepsis. Delay in diagnosis was common. In reporting these cases, we seek to highlight the diverse clinical spectrum and potentially misleading features of this condition. Clinicians must retain a high index of suspicion to avoid potentially catastrophic outcomes.

            A case report of successful treatment of secondary aortoenteric fistula complicated with gastrointestinal bleeding and retroperitoneal abscess in an elderly patient

            Abstract Rationale: The treatment of secondary aortoenteric fistula (SAEF) involves maintaining hemodynamic stability, infection control, revascularization, and surgical repair. Conventional open repair is associated with high mortality, whereas endovascular stent-graft repair is associated with recurrent infection or bleeding. Patient concerns: We report the case of an 85-year-old man with SAEF who presented with gastrointestinal bleeding and retroperitoneal abscess. Diagnoses: He was misdiagnosed for 5 months. SAEF was eventually diagnosed by CT and gastroduodenoscopy. Interventions: The patient underwent hybrid open surgery: extraanatomic left axillofemoral bypass graft reconstruction, exploratory laparotomy, aortic stent graft excision, infrarenal abdominal aortic suture, left common iliac artery ligation, extensive surgical debridement, and retroperitoneal abscess resolution and drainage, along with duodenal defect repair and jejunal feeding tube placement. Outcomes: He survived the complicated surgery and several life-threatening complications with multidisciplinary management. He has kept well for 15 months. Lessons: Elderly SAEF patients can undergo open repair when circumstances permit, but multidisciplinary management is crucial.
