[Advances in angiographic diagnosis for the demonstration of acral vascular processes]

At present the clinician may include the arteriographical demonstration of the acral vascular processes exactly into his diagnostical scheme only then, when this yields reproducible clear results. With the application of Droperidol it has become possible to improve decisively the angiographical examination technique. The method is simple and without risk. Thus a decisive progress in the secure differentiation of acral vascular processes has been achieved. The use of the technique can be recommended in general. Acral vascular processes show a typical picture in the arteriogramme. Apart from the occlusions of the vessels, irregularities of the wall and collaterals characteristic patterns of the findings are observed with regard to the localisation of the occlusion. The differential diagnosis concerning the stage in Raynaud's disease is clear and secure. The close cooperation between clinician and radiologist remains a necessary prerequisite for an optimum investigation technique and an exact diagnosing.
