title: The Allen test.
abstract: There has been renewed interest in radial artery bypass conduits for coronary artery revascularization, and surgeons should be familiar with methods of assessing circulation of the hand to determine which patients are candidates for this procedure. The Allen test originally was described in 1929, and this report reviews its initial description and contribution to our surgical heritage.
