[|AI|]  There can be many causes of dilatation of veins. It is usually the veins of the legs that get dilated. Veins of the anal canal and at the lower end of the food pipe also may get dilated in piles and chronic liver disease respectively. Dilatation of the veins only at the back over the scapula has to be considered to be due to some local factors which may or may not be significant. Local factors may be congenital, inflammatory or neoplastic. If a good physical examination and the routine investigations are normal, these venous dilatation are best ignored.
