Bruised veins in the legs result from blunt-forced trauma, coagulopathy, hemorrhages, blood infection, fractures and vein injuries. MedicineNet explains that the elderly often experience bruising in the legs after taking anticoagulants, such as Warfarin. This anticoagulant, which is commercially recognized as Coumadin, is prescribed for patients who have experienced previous clotting in the legs. Cortisone medicines also contribute to bruising, as they increase the fragility of small capillaries.
