Critical limb ischaemia: a case against Consensus II

Critical limb ischaemia (CLI) is a serious clinical condition that often immediately precedes limb loss. The Consensus Documents of 1989 and 1991 attempted to define CLI and give direction to its investigation and management. Whilst the need for such a consensus was clear and should be supported we believe the definition of CLI as documented in the Consensus Documents I and II recommendation number I is wrong. We present evidence from 140 patients with severe limb ischaemia taken from the PARTNER Group studies to support our request for an amendment to the ankle pressure recommendation from < or = 50 mmHg to >50 mmHg and big toe pressure from < or = 30 mmHg to >30 mmHg for the purpose of conducting clinical trials and to include Doppler index and tcPO2 as additional parameters. We also believe that the current document may be actually excluding the only group of patients likely to benefit from drug treatment or other interventions and that the above amendment should be prioritized.
