Summary

The in situ bypass technique is effective for critical limb ischemia in diabetic patients. While minor amputation rates were higher in diabetics, overall outcomes were comparable to non-diabetic patients.

Area of Science:

  • Vascular Surgery
  • Diabetic Complications
  • Lower Limb Ischemia

Context:

  • The study evaluated the efficacy of in situ bypass procedures for critical limb ischemia.
  • A cohort of 444 patients, including diabetic and non-diabetic individuals, underwent 483 procedures between 1986 and 1990.
  • Diabetic patients presented with more critical limb ischemia and lower distal anastomoses.

Purpose:

  • To assess the outcomes of in situ bypass surgery in diabetic versus non-diabetic patients with critical limb ischemia.
  • To compare patency rates, amputation rates, and survival between the two groups.

Summary:

  • Preoperative risk factors were similar, except for higher smoking rates and cardiac disease in diabetics.
  • Three-year primary and secondary patency rates were comparable (58% and 64%).
  • Diabetic patients experienced higher minor amputation rates, but major amputation rates were similar. Survival rates were lower in diabetics.

Impact:

  • The in situ bypass technique demonstrates significant utility in treating critical lower limb ischemia in diabetic patients.
  • Despite increased minor amputation risk, diabetic patients achieve comparable limb salvage and patency rates to non-diabetic patients.
  • Findings support the use of in situ bypass for diabetic patients with critical limb ischemia, highlighting the need for careful management of amputation risk.
