Summary

Elderly patients undergoing embolectomy face high mortality, especially those over 80 or with limb loss. While some long-term survivors exist, the benefit of anticoagulation remains unclear.

Area of Science:

  • Vascular Surgery
  • Geriatric Medicine
  • Cardiovascular Research

Background:

  • Embolectomy is a critical intervention for acute limb ischemia.
  • Assessing long-term outcomes after embolectomy in elderly populations is crucial for treatment optimization.

Purpose of the Study:

  • To evaluate the late outcomes and survival rates in elderly patients following embolectomy.
  • To identify factors influencing mortality and limb salvage in patients with embolism versus thrombosis in situ.

Main Methods:

  • A retrospective follow-up study of 113 elderly patients (median age 77) after embolectomy over 2-10.5 years.
  • Patients were categorized into embolism (n=84) and thrombosis in situ (n=29) groups.
  • Analysis of mortality, limb loss, and cardiovascular events, comparing anticoagulated and non-anticoagulated subgroups.

Main Results:

  • Thirty-day mortality was 39% in the embolism group and 55% in the thrombosis group.
  • Factors associated with mortality included age >80 years and failure to save the limb.
  • Limb loss was significantly higher in the thrombosis group (76%).
  • Mean long-term survival in the embolism group was 35 months, with higher early mortality.
  • No significant differences in mortality or cardiovascular events were observed between warfarin and non-anticoagulated patients.

Conclusions:

  • Mortality after embolectomy in the elderly is substantial, but a subset of patients achieve long-term survival.
  • Limb salvage and advanced age are critical determinants of early mortality.
  • The efficacy of long-term oral anticoagulation in improving outcomes after embolectomy requires further investigation.
