Area of Science:

  • Vascular Imaging and Interventional Radiology

Background:

  • Aorto-femoral angiography is crucial for diagnosing peripheral artery disease.
  • Transbrachial access offers an alternative to traditional femoral access for aorto-femoral angiography.

Purpose of the Study:

  • To evaluate the utility of a novel right-angled pigtail catheter for transbrachial aorto-femoral angiography.
  • To assess the ease and speed of catheter introduction using this device.

Main Methods:

  • A high-flow, right-angled, 5-gauge polyethylene pigtail catheter was utilized.
  • The transbrachial approach was employed in 24 patients undergoing aorto-femoral angiography.

Main Results:

  • The catheter's design facilitated straightforward and quick insertion into the abdominal aorta.

  • Successful aorto-femoral angiography was achieved in all patients.

    • Conclusions:

    • The right-angled pigtail catheter is effective for transbrachial aorto-femoral angiography.
    • Its configuration simplifies and accelerates catheterization, potentially improving procedural outcomes.
