further bedside tests

Last reviewed 01/2018

  • postural colour change - Buerger's test

  • persistent venous guttering

  • reactive hyperaemia - inflate a blood pressure cuff around the leg to a pressure of about 250 mm Hg. Keep for about 5 minutes. When the cuff is deflated, the leg should develop a red flush within a few seconds. This response is severely delayed in an ischaemic leg.

  • doppler flow studies e.g. ankle-brachial pressure index
