[Rhytidectomy and Raynaud's phenomenon: about two cases]

Raynaud's phenomenon is a currently vascular syndrome (8 to 10% of women and 3 to 5% of men). It was defined as episodic ischaemia of the fingers, toes, nose, ears and nipples, which presents clinically as pallor, cyanosis, and often rubor of the skins, in response to cold, emotional stimuli and vasoconstriction agents. The phenomenon is caused by a vasoconstriction of arterials skin. In severe forms of the phenomenon, we can see ulcerations and necrosis. We report here two cases of rhytidectomy flap necrosis in Raynaud's Phenomenon. After review of literature, we explain the elements of physiopathology whose can explain these complications and we try to establish recommendations to these complications.
