The measurement of skin blood flow in peripheral vascular disease by epicutaneous application of Xenon133
JP Kostuik, D Wood, R Hornby, S Feingold and V Mathews
Radioactive xenon133 applied epicutaneously was used to study the skin
blood flow below the knee in sixteen normal subjects, in eight patients
with peripheral vascular disease not requiring amputation, and in a blind
study of twenty-nine patients requiring amputation. Following these
twenty-nine amputations, the flow rates were made known and correlated with
the rates of healing. When the flow rates were above 1.5 milliliters per
minute per 100 grams of tissue (skin), the wounds generally healed. In
thirteen other patients, Syme or below-the-knee amputations were performed
on the basis of the flow rates, and all of the wounds healed. The test,
therefore, is now used routinely prior to amputation for peripheral
vascular disease as an adjunct to clinical judgment in the determination of
the level of amputation.
