Key words:vascular access, steal syndrome, skin perfusion pressure, critical limb ischemia 〈Abstract〉 【Background and Purpose】 Steal syndrome is diagnosed by integrating the objective findings and subjective symptoms. Since a serious ischemic symptom is accompanied by an ulcer, necrosis or irreversible neuropathy nerve paralysis, an objective rating method with high diagnostic capability is required. In severe ischemia of the lower limbs, it is reported that the measurement of skin perfusion pressure(SPP)is useful and is used for the decision on treatment policy and the judgment of the prognostic healing ability clinically. In this study, we examined the usefulness of SPP for dialysis-associated steal syndrome. 【Subjects and Methods】 This study involved 106 patients with vascular access obtained by measuring the SPP at our clinic. By an interview on the presence of steal symptoms during an examination, subjects were classified into four groups of Stage Ⅰ-Ⅳ by Fontaineʼs severity classification, with an additional fifth group without symptoms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
