Abstract ABSTRACT- A group of 45 lumbennen with uibration-induced attachs of Raynaud's syndrome URS) and a control group of 45 patients with primary Raynaud's syndrome (PRS) were qarnined by the diagnostic method of com-puteized telethermography (CCTT). The eraminations were first performed in the natiue state and then after the procedure of cryoactiuation. Results obtained suggested the population of patients with PRS to be telethermographically characteised by high LTG ualues for all fingers except the second one, a mild degree of anisothermia and ftequent occurrence of thermic amputation. Follow-ing cryoactiuation, howeuer, thertrtic amputation wa.s euen more common a,nd the degree of anisothermia lower. Concerning the group of patients with VRS, telethermography reuealed thern to be on an auerage characteised by nonnal LTG ualues with frequent inuersion, rare occurrence of thenttic amputation and corrlrrlon anisotherrnia. In the population of patients with PRS, cryoactiuation was followed by a significant increase in the percentage of thermic amputation, whereas the percentage of cases of anisotherm,ia decreased relatiue to natiue telethermography. In uiew of these results, we thinh that in patients with PRD, attachs are caused by functional central hyper-refl*ion. In patients with VRS, this hyper-reflexion organically caused by peripheral lesions with secondary deuelopment of central deneruation hypersensitiuity, with the spinal leuel most probably being the fi.rst stage of this hypersensitiuity. Our study showed the differentia-tion betuteen pimary and secondary Raynaud's syndrome by CCTT to be uery sirnple and reliable.
