title: Axillo-femoral bypass and simultaneous removal of the aorto-femoral vascular infection site: is the procedure safe?
abstract: In a retrospective analysis 12 patients treated for aorto-femoral vascular infections between 1984 and 1990 were evaluated. They were all male with a mean age of 63 years. Indications for treatment were: mycotic aneurysms-3, primary aorto-enteric fistula-2 and graft infection-7. Surgical treatment consisted of implantation of an extra-anatomic bypass, carefully avoiding the infected area, followed by removal of the infected graft and tissue at the same session. There was no early mortality (less than 30 days) but the first year mortality was 42% (n = 5). Causes of death were: aortic stump disruption (n = 1), recurrence of aorto-enteric fistula (n = 2), axillary anastomosis disruption (n = 1), cardiac failure (n = 1). Orthotopic reconstruction of the aorta after 12 months, as we advocate, was accomplished in two patients and is scheduled in another one. In two patients their poor condition precluded this second step, and in two further patients above-knee amputation with subsequent extra-anatomic graft removal was needed. Only one of the 12 extra-anatomic bypasses became infected. Reconstruction by axillo-femoral bypass combined with removal of the aorto-femoral graft at the same session is a practicable procedure with good early results. However, the rate of successful orthotopic reconstruction of the aorta after 12 months is low because of a high mortality rate, especially in the presence of aorto-enteric fistulas, and because some patients with well functioning axillo-femoral grafts are in too poor condition for another large operation.
