What are the main risk factors for superficial vein thrombosis? Most cases of superficial vein thrombosis occur in people with varicose veins, so they tend to happen spontaneously in someone who's got varicose veins or maybe as a result of kind of minor trauma, so bumping your leg. In people with normal veins, it can be associated with what we call thrombogenic conditions, so conditions in which you've got blood that's more likely to clot. They include but are not limited to inflammatory bowel disease, SLE, and can rarely be associated with cancer as well. This highlights the importance of if you develop superficial vein thrombosis, you should first of all seek treatment for it, but then during that consultation you should undergo a thorough history and examination to ensure that there's nothing else going on.
