Scores and stages in angiology

For the classification of peripheral arterial disease the Fontaine's stages are mostly used in Switzerland whereas the Rutherford's categories are more common in the scientific literature. It is important to distinguish between the Rutherford classification for - chronic peripheral artery disease and the one for the acute limb ischemia. The clinical classification of acute limb ischemia is a helpful tool for prognosis of the leg and urgency of revascularization. The clinical classification of acute limb ischemia is a helpful tool for prognosis of the leg and urgency of revascularization. The Wagner as well as the Armstrong classification is used for diabetic foot ulcers. The advantage of the - Armstrong stages is that important informations like wound infection or ischemia are considered. For chronic venous insufficiency the Widmer stages are widely used in Switzerland but have the disadvantage that patient- reported symptom severity is not considered. The CEAP classification includes anatomical information and the etiology and is mostly used for studies. The Wells score helps to define the probability for the presence of a deep vein thrombosis before further tests are performed.
