Elderly patients aged 70+ undergoing peripheral arterial reconstruction for arteriosclerosis obliterans have similar operative mortality but higher long-term mortality compared to younger patients. However, limb salvage rates remain high, supporting surgical intervention.

Area of Science:

  • Vascular Surgery
  • Geriatric Medicine
  • Cardiovascular Research

Background:

  • Peripheral arterial obstruction due to arteriosclerosis obliterans is a significant health concern, particularly in elderly populations.
  • Surgical intervention is a primary treatment modality, but its efficacy and safety in older patients require careful evaluation.

Purpose of the Study:

  • To analyze the surgical outcomes of primary peripheral arterial reconstruction in patients stratified by age.
  • To compare operative mortality, long-term survival, graft patency, and limb salvage rates between elderly (>=70 years) and younger (<70 years) patient groups.

Main Methods:

  • Retrospective analysis of 121 procedures in 95 patients aged >=70 years (Group 1) and 215 procedures in 148 patients aged <70 years (Group 2).
  • Comparison of operative mortality, long-term mortality, 5-year survival, 5-year graft patency (suprainguinal and infrainguinal), and 5-year limb salvage rates between the two age groups.

Main Results:

  • Operative mortality rates were similar (4% vs. 3.4%).
  • Long-term mortality was significantly higher in the elderly group (33% vs. 18.9%, P < 0.05), with cardiac failure being the most common cause of death.
  • Cumulative 5-year survival rates were lower in the elderly group (56.3% vs. 78.3%, P < 0.0001).
  • Suprainguinal bypass graft patency and limb salvage rates were comparable between groups, while infrainguinal reconstruction showed a trend towards lower patency in the elderly group.

Conclusions:

  • Despite higher long-term mortality, elderly patients aged 70 and above experience comparable operative mortality and limb salvage rates following peripheral arterial reconstruction.
  • The findings support an aggressive surgical approach for arteriosclerosis obliterans in elderly patients, acknowledging the increased risk of long-term mortality, primarily due to cardiac causes.
