Neurovascular Cases

  • Cerebral arteriography is increasingly performed using a transradial artery approach.
  • The transradial approach is gaining popularity in other fields as well. For example, in the field of interventional cardiology, the transradial artery approach is becoming the standard of care for diagnostic and interventional procedures, replacing the traditional transfemoral approach.
  • Randomized cardiology trials have repeatedly demonstrated multiple advantages of the transradial approach including ↓ complications, ↓ mortality, ↓ costs, and ↑ patient satisfaction, in comparison to the transfemoral approach.
  • The endovascular anatomy of the right radial artery through the aortic arch and into the supraaortic vessels presents a unique technical challenge because the arch intersection is entered from a different inlet, namely the brachiocephalic trunk.

Fluoroscopy shows the J-shaped guiding wire and the diagnostic catheter advancing through the right radial → brachial → subclavian → brachiocephalic arteries, en route to the aortic arch.
