  • Title: Raynaud's phenomenon: peripheral catecholamine concentration and effect of sympathectomy.
    Author: Nielsen SL, Christensen NJ, Olsen N, Lassen NA.
    Journal: Acta Chir Scand Suppl; 1980; 502():57-62. PubMed ID: 6941602.
    Abstract:
    The reaction to body and finger cooling was recorded in seven patients with relapse of primary Raynaud's phenomenon after sufficiently performed bilateral upper thoracic sympathectomy and for comparison in eight young women with primary Raynaud's phenomenon as well as in seven normal women. The forearm venous concentration of noradrenaline was lower and adrenaline concentration higher in the sympathectomized patients than in the other groups (p less than 0,05). Noradrenaline showed a significant increase during body cooling in normals and primary Raynaud's (p less than 0,05). There was no significant correlation between the vasoconstrictor response to cooling of a finger and the noradrenaline concentration probably due to the fact that skin vasoconstriction impeded release of noradrenaline from the skin. The relapse of Raynaud's phenomenon after surgically sufficient sympathectomy could not be treated by reserpine or alfa-adrenergic receptor blockers in two patients in whom this was tried.
