Transradial coronary intervention without pre-screening for a dual palmar blood supply

Int J Cardiol. 2007 Oct 18;121(3):320-2. doi: 10.1016/j.ijcard.2006.11.009. Epub 2006 Dec 28.


It is usual practice to determine the presence of collateral blood supply to the hand prior to radial artery cannulation. We propose that pre-screening for a dual palmar vascular supply is not necessary and the presence of a palpable radial pulse is sufficient to allow successful radial artery cannulation. We retrospectively analysed our interventional PTCA registry, including only patients who had a transradial procedure without being pre-screened with an Allen's test or plethysmography. We report our data including complications the day after the procedure and at 30 days, and provide an up to date discussion on the need to assess patients for a dual palmar blood supply prior to transradial intervention.
