Summary

Advancements in contrast agents and digital subtraction angiography (DSA) have significantly improved arteriography safety and reduced patient discomfort. However, potential late adverse effects from contrast media require continued attention.

Area of Science:

  • Vascular Imaging
  • Radiology

Background:

  • Arteriography has evolved significantly due to improved contrast agents and digital subtraction angiography (DSA).
  • Nonionic monomer contrast agents offer lower osmolality, reducing patient discomfort and serious complications.
  • Despite advancements, late-onset adverse effects of contrast media remain a concern.

Purpose of the Study:

  • To review the changes in indications, risks, and limitations of arteriography.
  • To highlight the impact of new contrast agents and DSA on patient outcomes.
  • To emphasize the importance of collaboration in arteriography for conditions like arteriosclerosis obliterans (ASO).

Main Methods:

  • Review of recent advancements in contrast media and angiography techniques.
  • Discussion of the role of digital subtraction angiography (DSA) in outpatient settings.
  • Emphasis on the need for interdisciplinary communication between vascular surgeons and radiologists.

Main Results:

  • Improved contrast agents (nonionic monomers) have decreased patient-reported heat sensation, vasodilatation, and injection pain.
  • Digital subtraction angiography (DSA) enables less invasive, outpatient arteriography due to thinner catheters.
  • Serious complications associated with arteriography have been markedly reduced.

Conclusions:

  • Modern arteriography offers improved patient comfort and safety profiles.
  • DSA has revolutionized arteriography, making it more accessible and less invasive.
  • Precise understanding of pathophysiology and vascular anatomy, coupled with collaborative discussion, is crucial for effective arteriography, especially in ASO patients.
