Peripheral arterial reconstruction has advanced significantly, improving outcomes for arteriosclerosis obliterans. While aorto-iliac bypass shows high patency, infrainguinal bypass with autogenous vein grafts still faces long-term challenges.

Area of Science:

  • Vascular Surgery
  • Arterial Reconstruction
  • Peripheral Artery Disease

Context:

  • Advances in diagnostic technology (e.g., Doppler ultrasound) and surgical techniques have improved peripheral arterial reconstruction.
  • Over 14 years, 1,200 cases (1,660 limbs) of peripheral arterial reconstruction were performed, primarily for arteriosclerosis obliterans.

Purpose:

  • To review outcomes of peripheral arterial reconstruction, focusing on aorto-iliac and infrainguinal bypass procedures.
  • To identify current challenges and areas for improvement in vascular reconstruction surgery.

Summary:

  • Aorto-iliac occlusive lesions treated with Dacron prostheses achieved an 11-year secondary patency rate of 96.5%, with low rates of anastomotic aneurysm and graft infection.
  • Infrainguinal bypass using autogenous vein grafts (AVG) demonstrated 5-year primary (secondary) patency rates exceeding 70% (85%), but long-term graft occlusion remains a concern.

  • No current graft material surpasses AVG, and long-term environmental pathological changes in AVG present ongoing challenges in vascular reconstruction.

    • Impact:

    • High success rates for aorto-iliac bypass highlight the effectiveness of prosthetic grafts in specific arterial regions.
    • The persistent challenges in infrainguinal bypass emphasize the need for further research into graft materials and long-term patency solutions.
    • Continued patient follow-up is crucial for maintaining graft patency and improving the quality of life for patients undergoing peripheral arterial reconstruction.
