Routine angioscopy during lower extremity revascularization is feasible and safe. A dedicated irrigation pump effectively clears blood, yielding high-quality images and aiding clinical decisions.

Area of Science:

  • Vascular Surgery
  • Medical Imaging

Background:

  • Blood obscures visualization during angioscopy, limiting its routine use.
  • Current methods like local irrigation offer suboptimal clarity.

Purpose of the Study:

  • To assess the feasibility, clinical utility, and safety of routine angioscopy during lower extremity revascularization.
  • To evaluate a novel irrigation pump system for improving intraoperative visualization.

Main Methods:

  • 136 intraoperative angioscopies were performed during various lower extremity revascularization procedures.
  • A dedicated irrigation pump system using balanced salt solution was employed.
  • Visual quality and failure rates were recorded; clinical decisions based on findings were documented.

Main Results:

  • Good visual quality was achieved in over 80% of angioscopies.
  • The overall failure rate was low at 1.8%.
  • 78 clinical or surgical decisions were influenced by angioscopy findings in 71 cases.

Conclusions:

  • Routine angioscopy with a dedicated irrigation pump is a feasible, safe, and clinically useful tool in lower extremity revascularization.
  • The system provides consistent high-quality studies, aiding surgical decision-making.
  • No complications were linked to the angioscope or irrigation pump.
