Delayed occurrence of radial artery pseudoaneurysm following transradial percutaneous coronary intervention.

Radial artery pseudoaneurysm is rare following transradial catheterization procedures. In this article, we report a 5-month delay in the occurrence of this vascular complication following the completion of transradial coronary intervention in a subject without any underlying vasculitis, representing the longest time lag thus far described. <Learning objective: The occurrence of radial artery pseudoaneurysms after transradial coronary intervention is extremely rare, but typically presents clinically within weeks following arterial cannulation. A 5-month time delay for radial artery pseudoaneurysm occurrence in an individual without underlying vasculitis has not been previously reported. It is compulsory that radial operators have full knowledge of the time courses of all potential radial artery complications, so that their timely correction can be instituted.>.
