Age versus comorbidities as risk factors for complications after elective abdominal aortic reconstructive surgery

Abstract

For patients undergoing elective AAR, increasing patient age is associated with a small increase in risk for in-hospital morbidity or mortality. However, significant cardiac, pulmonary, or renal disease is associated with a much greater risk of postoperative complications, and, therefore, advanced age should not be the sole basis of exclusion for otherwise suitable candidates for elective AAR.

Endovascular Stent Grafting Versus Open Surgical Operation in Patients With Infrarenal Aortic Aneurysms

“…Thus, superior early postoperative mortality rates between 1% and 2% are only achieved in low-risk patients with better compensating capabilities but without significant organ dysfunctions. 14,15,20 As previously shown, 14,15,18,33 we were also able to demonstrate that advanced age and renal or pulmonary dysfunction adversely influence postoperative outcome. In our series, younger patients without these risk factors revealed a postoperative mortality rate below 1%, whereas geriatric patients under the strain of such risk factors had unacceptably high mortality rates approaching 20%.…”

Renal dysfunction and prolonged visceral ischaemia increase mortality rate after suprarenal aneurysm repair

“…Preoperative renal dysfunction has been shown by many to influence mortality after TAA 1,8,12 -15 . Others have shown age 1,8,12,14,15 , a history of ischaemic heart disease 8,12,13 and poor respiratory function 1,8,12 to have major adverse effects. The thorough preoperative assessment and treatment of underlying cardiac disease may explain the absence of a relationship between cardiac disease and death in the present series.…”

Effect of increasing patient age on complication rates following intact abdominal aortic aneurysm repair in the united states1

“…Older age is usually considered a significant risk factor for increased operative mortality [1]. The basis for this increased risk may be due to coexisting comorbidities in the elderly [2][3]. Several case-series from tertiary care centers suggest that, contrary to this general perception, no additional risk exists for elderly patients undergoing major surgery [4 -5].…”
