Peripheral angioplasty outcomes were assessed using isotope limb blood flow studies. A significant number of untreated limbs also showed reduced blood flow, suggesting systemic factors may affect outcomes.

Area of Science:

  • Vascular Surgery
  • Interventional Cardiology
  • Radiology

Background:

  • Peripheral angioplasty aims to improve limb blood flow.
  • Assessing angioplasty success requires evaluating blood flow changes.

Purpose of the Study:

  • To evaluate the outcome of peripheral angioplasty using isotope limb blood flow studies.
  • To compare different angioplasty techniques (balloon, laser, Kensey).

Main Methods:

  • Isotope limb blood flow and Doppler ankle-brachial pressure measurements were taken before and 6 months after angioplasty.
  • 101 angioplastied limbs and 53 contralateral untreated limbs were studied.

Main Results:

  • 17% of angioplastied limbs showed a decrease in blood flow at 6 months, with no significant difference between techniques.

  • 25% of untreated limbs also showed reduced blood flow.
  • Reduced blood flow in untreated limbs was more common when the treated limb did not improve.

    • Conclusions:

    • A fall in limb blood flow post-angioplasty may not solely indicate angioplasty failure.
    • Systemic factors might adversely affect blood flow in both treated and untreated limbs in some patients.
