Temporizing stent graft for aortoenteric fistula with massive gastrointestinal hemorrhage.

ABSTRACT

OBJECTIVES: We present a case of a 59-year-old male with an actively bleeding aortoenteric fistula (AEF) that was temporized using an endovascular stent prior to staged open reconstruction. METHODS: Verbal informed consent was given by the patient's family for publication of this case report. The patient presented with pulseless electrical activity secondary to hemorrhagic shock due to a massive gastrointestinal bleed. His past surgical history included an aortobifemoral bypass (ABFB) that subsequently underwent extra-anatomic reconstruction with right axillofemoral artery bypass for right femoral infected pseudoaneurysm. Two months prior to presentation, he underwent a second revision with in-situ reconstruction for left limb graft infection. CTA now demonstrated actively bleeding AEF. He was emergently treated with endovascular stenting. Once stabilized, a two-stage revision with extra-anatomic bypass and aortic stump closure for management of his AEF was performed. RESULT: The patient was adequately stabilized using endovascular techniques followed by two-stage revision but unfortunately expired secondary to septic shock 20 days postoperatively. CONCLUSION: This case highlights the utility of endovascular stent graft to successfully obtain hemodynamic stability and optimization prior to open repair of AEFs.
