[Differential diagnosis of acral blood circulation disorders using intra-arterial DSA of the hand].

32 patients with secondary Raynaud's syndrome and known basic disease (thromboangiitis obliterans, arterial sclerosis, collagenosis) were examined by high-resolution arterial subtraction angiography. There were typical organic fixed vessel irregularities in relation to the extent of the disease. In early stages, however, the functional vasospastic disorder dominates. The extent and the reversibility of the vasospasm were documented after pharmacological treatment. Pharmacoangiography of the hand can therefore be used as helpful method in the differential diagnosis and therapy of Raynaud's syndrome.
