Abstract
Evaluation of the local haemodynamic changes was performed in 93 patients with untreated reflex sympathetic dystrophy, based upon a simple dynamic vascular examination technique, using 99Tcm-HSA. According to the disease stage, opposite observations were made: in stage I (n = 72) an increase in both blood flow and blood volume was found, in stage II (n = 21) in contrast, both blood flow and blood volume decreased. These findings show that reflex sympathetic dystrophy can be staged according to haemodynamic changes. It is obvious, moreover, that a careful haemodynamic staging is most important for the choice of the right vasoactive treatment; e.g. calcitonin (vasoconstrictive) versus guanethidine (vasodilating).Keywords
