Summary

The transradial approach offers a safer method for selective cerebral angiography compared to traditional transfemoral and transbrachial techniques. This less invasive procedure reduces patient discomfort and serious complications, making it a viable alternative.

Area of Science:

  • Vascular Surgery
  • Interventional Neuroradiology

Background:

  • Traditional transfemoral and transbrachial approaches for selective cerebral angiography carry risks.
  • These methods often involve prolonged compression and potential serious complications like pulmonary embolism.

Purpose of the Study:

  • To evaluate the safety and efficacy of the transradial approach for selective cerebral angiography.
  • To present the transradial approach as a less invasive alternative to existing methods.

Main Methods:

  • A transradial approach using a 4-F catheter was performed in 70 patients between July 1997 and November 1998.
  • Allen's test confirmed collateral hand circulation; a 20 cm arterial introducer prevented radial artery spasm.

Main Results:

Related Experiment Videos

  • Successful radial artery puncture and cannulation were achieved in all patients.
  • High success rates for selective catheterization were observed: >98% for carotid and >95% for vertebral angiography.
  • No major vascular complications, including cerebral infarction or limb ischemia, were reported.

    • Conclusions:

    • The transradial approach is a safe and less invasive technique for selective cerebral angiography.
    • This method presents a promising alternative to transfemoral and transbrachial approaches for cerebral angiography.
