IntroductionThe purpose of this meta-analysis was to determine the value and efficacy of skin perfusion pressure (SPP) for the prediction of wound healing in patients with critical limb ischemia.Material And MethodsMedline, Cochrane, EMBASE, and Google Scholar databases were searched from inception until December 31, 2014 using combinations of the following keywords: skin perfusion pressure, limb ischemia, wound healing, prediction. Randomized controlled trials, 2-arm prospective studies, and retrospective studies that measured SPP in patients with limb ischemia were included. The outcome was the sensitivity and specificity of SPP for the prediction of wound healing.ResultsFive studies were included in the meta-analysis. The mean patient age ranged from 62.2 to 71.5 years, and the majority were male. The pooled sensitivity of SPP for the prediction of wound healing was 79.9% using 30 mm Hg as the cut-off, 67.1% using 40 mm Hg, and 76.1% for all included studies (95% CI: 73.9-84.9%, 55.8-76.8%, and 70.7-80.8%, respectively). The pooled specificity was 78.2% using 30 mm Hg, 84.2% using 40 mm Hg, and 82.1% for all included studies (95% CI: 61.5-89.0%, 74.0-90.9%, 73.7-88.3%, respectively).ConclusionsSkin perfusion pressure can accurately predict wound healing in patients with critical limb ischemia.
