Raynaud's phenomenon and gangrene following snake envenomation.

Local necrosis and gangrene at the site of the bite are commonly observed after snake envenomation. However, Raynaud's phenomenon and gangrene occurring in a limb other than that bitten by the snake is encountered rarely. So far, there is only one report of such an episode in literature. Here we are reporting a case of patient with snake bite on the right foot following which he developed Raynaud's phenomenon of the left upper limb and dry gangrene of the tips of the left index and middle fingers. The snake was identified as Russel's viper.
