title: Quantitative assessment of the effectiveness of chemical lumbar sympathectomy.
abstract: Twenty-one chemical sympathectomies were assessed in this study by taking infra-red thermograms of the feet before and after the procedure. Patients with relatively high perfusion pressures were shown to have the best response, while those with a low perfusion pressure had little or no increase in mean temperature in the foot.
