Summary

Diabetic patients undergoing lower-limb revascularization often have multiple leg artery occlusions. Assessing lower leg and foot artery visualization is crucial for evaluating distal vascular runoff and predicting surgical outcomes.

Area of Science:

  • Vascular Surgery
  • Angiology
  • Diabetic Complications

Background:

  • Lower-limb revascularization is critical for limb salvage in patients with peripheral artery disease.
  • Atherosclerotic involvement of distal arteries significantly impacts surgical success.
  • Diabetic patients often present with more severe peripheral artery disease.

Purpose of the Study:

  • To analyze atherosclerotic involvement in lower leg and foot arteries during lower-limb revascularization.
  • To determine the prognostic significance of distal vascular runoff.
  • To evaluate the importance of complete arterial visualization for surgical planning.

Main Methods:

  • Intraoperative serial angiography in 194 patients (206 limbs) undergoing lower-limb revascularization.

  • Assessment of atherosclerotic involvement in lower leg and foot arteries.
  • Correlation of angiographic findings with patient outcomes.

    • Main Results:

    • 71% of diabetic patients had two or three leg vessel occlusions, compared to 52% of non-diabetics.
    • The peroneal artery was less frequently affected than other leg arteries.
    • Severe foot artery involvement was common in patients with limited patent leg vessels; the posterior foot arch was less affected than the anterior.

    Conclusions:

    • Complete visualization of lower leg and foot arteries is essential for adequate evaluation of distal vascular runoff.
    • Pedal runoff assessment holds prognostic significance for femoropopliteal and femorodistal bypass surgery.
    • Understanding distal arterial disease patterns aids in optimizing revascularization strategies, especially in diabetic patients.
