[Acute and subacute acral ischemia syndromes (author's transl)].

Acute and subacute acral ischemia syndromes must be carefully distinguished from chronic intermittent acral disturbances of circulation because of the differences in the genesis, in the clinical picture and in the treatment. Vasoconstriction caused by cold or emotion and which disappears on warming is the principal feature of the chronic intermittent syndromes. Prestasis and stasis are the basis of the ischemia of acute and subacute syndromes, which cannot be relieved by warmth. Vasodilation measures have no effect, whereas the circulation can be restored by the improvement of the fluidity and the flow conditions of the blood.
