Observations on the Raynaud's disease

During the last 25 years, owing to the improvement of the diagnostic means, the cases of "Raynaud's phenomenon" with well known etiology have been increasing and according to some authors they should be considered clearly prevailing. Through a right prevention and a medical and surgical therapy it is possible to obtain significant results. Consequently it is important to carry out a diagnostic screening. A study concerns 68 cases have been carried out in the Institute of Vascular Surgery, University of Milan, during the period 1971-1974. The cases are divided in two groups: idiopathic forms (disease) and forms connected to identifiable etiologies (syndrome). Many of the clinical parameters studied are examined. The so-called idiopathic forms: 47 cases (69%) with an average age of 45 years and a clear female prevalence (33 against 14). The forms with an identifiable etiology: 21 (31%) with an average age of 31 years and a clear male prevalence (16 against 5). It is therefore observed that the idiopathic Raynaud's disease is still prevailing and particularly in women. In idiopathic forms brachial angiography shows in most of the cases X-ray evidence of digital artery occlusion.
