Summary

Selective catheterization in elderly patients is challenging due to aortic changes. A specialized guide wire enabled safe femorocerebral angiography in most elderly patients, ensuring patent left subclavian arteries.

Area of Science:

  • Vascular Surgery
  • Interventional Radiology
  • Geriatric Medicine

Background:

  • Selective catheterization and angiography of brachiocephalic vessels present challenges in elderly patients.
  • Aortic tortuosity and unfolding in older individuals complicate these procedures.

Purpose of the Study:

  • To evaluate the efficacy of a specialized guide wire for safe femorocerebral angiography in the elderly.
  • To assess the success rate and safety of using the Simmons sidewinder catheter in this patient population.

Main Methods:

  • The study involved selective catheterization and angiography of brachiocephalic vessels in elderly patients.
  • A special guide wire was utilized in conjunction with the Simmons sidewinder catheter.
  • Femorocerebral angiography was performed in 48 elderly patients.

Main Results:

  • The specialized guide wire facilitated successful and safe femorocerebral angiography in 47 out of 48 elderly patients.
  • All 47 patients who underwent successful angiography had a patent left subclavian artery.
  • The technique proved effective despite pre-existing aortic tortuosity and unfolding.

Conclusions:

  • A specialized guide wire significantly improves the success and safety of femorocerebral angiography in elderly patients.
  • The Simmons sidewinder catheter, with this guide wire, is a valuable tool for navigating complex aortic anatomy in older adults.
  • The procedure ensures the patency of critical arteries like the left subclavian artery.
