What causes prominent veins on body in a child after chiari malformation surgery?
Patient: My daughter is 12 years old and she got out of the shower last night and her legs were blueish/purple and veins all over her body were highly noticable (Bright Colored). The color is still faintly there but it shows up more after a shower. She has not pain or tingling but she did have Chiari Malformation surgery a year ago. Could this be a complication or what is this?? Doctor: Hi,  By what you say I feel that this could be ambient temperature induced reticular formation on the skin which is physiological and does not require any treatment at all.  I do not think this is related to the surgery which has been performed 1 year back.  This is medically called status marmoratus but at the same time to be 100% sure I would suggest that you upload an image.  Hope I have answered your query. Let me know if I can assist you further.
