[Radiological investigation in Raynaud's syndrome: meaning and limits (author's transl)].

The authors review the past five year's case history covering the humeral arteriographies carried out for the purpose of studying the vascularization of the hand in patients presenting Raynaud-like symptomatology. It is pointed out that in the majority of cases digital arteries show significant lesions and that a certain percentage of these are accompanied by haemodynamically significant alterations of the peripheral part of arteries of the forearm and of the metacarpus. Deep general narcosis is fundamental for a correct interpretation of the angiographies. Within the cases recorded the clinical data are a concomitant of arterious lesions typical of Raynaud's disease.
