Raynaud Phenomenon

Abstract

1. The production of the colour changes occurring in Raynaud Phenomenon has been discussed. 2. Clinically the patients have been grouped into (a) primary or idiopathic; (b) secondary to obliterative vascular disease; (c) secondary to the development of a 'local fault.' 3. The differentiation of the above cases has been described. 4. The limitations of sympathectomy and vasodilator drugs in the treatment of Raynaud Phenomenon have been discussed.
