Fenômeno de Raynaud descreve uma resposta vascular exagerada a temperatura fria ou estímulos emocionais, resultando em isquemia digital episódica. É caracterizada por vasoconstrição paroxística produzindo inicialmente palidez, componente essencial para o diagnóstico, seguida de cianose e eritema. A doença de Raynaud primária é um transtorno isolado inócuo. O fenômeno de Raynaud secundário ocorre em associação com uma ampla gama de transtornos diferentes, incluindo disproteinemias e doenças autoimunes sistêmicas não específicas de órgãos. | |||
