Objectives:
The objective of this study is to retrospectively analyse surgical outcomes in patients aged 75-79, and 80 and above.
Methods:
Between 2000 and 2015, 108 patients aged 75-79 (G 75 , mean age 76.9 ± 1.5years) and 72 patients aged 80 and above (G 80 , mean age 82.2 ± 2.1years) underwent elective aneurysm repair. Operative outcome and survival was compared with 727 contemporary younger counterparts aged <75 years (G Ctrl , mean age 56.6 ± 11.7years).
Results:
Postoperatively, patients with advanced age showed a higher incidence of prolonged ventilation (G 80 21.4%, G 75 8.4%, G Ctrl 2.9%; P < 0.001), low cardiac output syndrome (G 80 11.4%, G 75 1.9%, G Ctrl 2.2%; P = 0.001), multi organ failure (G 80 2.9%, G 75 0%, G Ctrl 0.1%; P = 0.022), haemofiltration (G 80 8.6%, G 75 0.9%, G Ctrl 0.6%; P < 0.001), and infection (G 80 10.0%, G 75 6.5%, G Ctrl 3.5%; P = 0.017). Operative mortality was significantly increased in the elderly (G 80 11.1%, G 75 3.7%, G Ctrl 1.4%; P < 0.001). Mid-term survival differed significantly between the surgical groups. Multivariate regression analysis precluded age as an independent predictor of operative mortality.
Conclusions:
Elderly patients showed a higher operative risk compared to their younger counterparts. However, age per se is no suitable indicator of surgical risk and well-selected patients with large threatening aneurysms may benefit from intervention.
