Retrospective review of 100 cases of endoluminal aortic stent-graft surgery from an anaesthetic perspective

One hundred cases of endoluminal aortic stent surgery were retrospectively reviewed and analysed with respect to outcome. We overall mortality rate was consistent with standard rates for open surgical repair One hundred per cent of patients who developed multiorgan failure died (7), as did 78% of those who developed acute renal failure (9), and 55% of those who had a serum creatinine rise greater than 100 mu mol/l (9). Patients given mannitol had an increased incidence of a serum creatinine rise of greater than 100 mu mol/l, at 16% verus 4% for those nor given mannitol. Patients with documented intra-or postoperative anaemia (Hb less than or equal to 80 g/l) had a mortality rate of 22% compared to 5% for non-anaemic patients. The mortality rare increased from 3% to 15% if the procedure took more than four hours. The anaesthetic requirements for this new type of surgery are outlined and discussed with respect to these results. The surgical technique is summarized.
