  • Title: Management of primary aortic graft infection by extra-anatomic bypass reconstruction.
    Author: Lehnert T, Gruber HP, Maeder N, Allenberg JR.
    Journal: Eur J Vasc Surg; 1993 May; 7(3):301-7. PubMed ID: 8513910.
    Abstract:
    In this retrospective study, 21 patients requiring treatment for primary infection of an aortic prosthesis between 1981 and 1991 were identified from a prospective register. Ten of the 21 patients had had additional peripheral reconstructive vascular surgery before the diagnosis of aortic graft infection. The median interval between aortic graft insertion and diagnosis of graft infection was 16 months (range 1-84). Infected grafts were removed and an extra-anatomic bypass constructed in all patients. All but three patients had axillodistal reconstruction. Six patients had simultaneous operations, whilst the other 15 patients had a staged procedure with extra-anatomic reconstruction preceding graft removal. Two patients died before discharge from the hospital (9.5%). No patient required extremity amputation in the perioperative period. By life-table analysis patient survival (including perioperative deaths) was 80% at 1 year, 55% at 3 years and 40% at 5 years. Primary patency was 62% at 1 year, 51% at 3 years and 40% at 5 years. Limb salvage rate was 89% at 1 year, 63% at 3 years and 63% at 5 years. The median length of follow-up was 24 months. Extra-anatomic reconstruction in patients with aortic graft infection can be performed with low perioperative mortality. Limb salvage rates following extra-anatomic reconstruction are determined not only by the mode of reconstruction, but also by the primary disease.
