AB Raynaud  phenomenon  (RP)  is  an  exaggeration  of  the  normal  vasospastic  reaction  to  cold  environments  or  emotional  stress*.Characterized  by  well-demarcated  color  changes  (pallor,  cyanosis,  hyperemia)  involving  the  peripheral  digits  (fingers  and  toes).Classified  clinically  into  primary  or  secondary  forms.Primary  RP  is  idiopathic  and  functional  in  nature,  the  integrity  of  the  blood  vessel  architecture  is  preserved.Secondary  RP  is  associated  with  an  underlying  structural  vasculopathy  and  may  be  complicated  by  digital  ischemia,  recurrent  digital  ulcerations,  rapid  deep  tissue  necrosis,  and  amputation.The  principal  approach  in  the  management  of  RP  entails  preventative  measures  through  the  avoidance  of  cold  environments  and  use  of  protective  clothing  to  maintain  adequately  warm  core  and  peripheral  body  temperatures.Therapeutic  agents  are  indicated  if  quality  of  life  is  affected  adversely  or  if  there  are  complications  of  tissue  ischemia,  including  digital  ulcers.
