Surgical repair of popliteal aneurysms offers good limb salvage rates. Early revascularization is recommended, with autologous saphenous vein grafts showing the best long-term patency compared to synthetic options.

Area of Science:

  • Vascular Surgery
  • Atherosclerotic Disease
  • Reconstructive Surgery

Background:

  • Popliteal aneurysms are a significant cause of limb ischemia, often presenting late.
  • Atherosclerotic popliteal aneurysms are more common than those related to entrapment.
  • Asymptomatic aneurysms can progress to ischemic complications, necessitating intervention.

Purpose of the Study:

  • To review a 15-year experience with popliteal aneurysms.
  • To evaluate the outcomes of surgical revascularization and limb salvage.
  • To compare the long-term patency rates of different graft materials.

Main Methods:

  • Retrospective review of 50 popliteal aneurysms in 36 patients.
  • Analysis of outcomes based on preoperative symptoms (asymptomatic vs. ischemic).

  • Comparison of graft patency: autologous saphenous vein (ASV), polytetrafluoroethylene (PTFE), and Dacron.

    • Main Results:

    • No operative deaths occurred in 45 vascular reconstructions.
    • Late patency rates: ASV (100%), PTFE (74%), Dacron (34%).
    • Overall limb salvage rate was 88%; grafts in asymptomatic limbs or with good runoff had better outcomes.

    Conclusions:

    • Surgical revascularization for popliteal aneurysms yields good results and is recommended, even in asymptomatic stages.
    • Autologous saphenous vein grafts are superior for long-term patency.
    • PTFE grafts are acceptable when ASV is unavailable; Dacron grafts are no longer indicated.
