[The indications for lumbar sympathectomy as a function of clinical findings and of the results of the angiographic test].

Indications for lumbar sympathectomy are presented as a function of the clinical findings and results of angiography, voluntarily ignoring data from non-invasive vascular function tests, in an attempt to answer two questions. Firstly, can the decision to perform lumbar sympathectomy depend on clinical findings only in 1983? Secondly, is angiography essential in all cases before sympathectomy? The positive response to both questions is based on a study of approximately 2,300 case reports.
