How to treat vascular inflammation: 1. If superficial phlebitis occurs incidentally, it may be accompanied by superficial venous thrombosis, which is mostly caused by the stimulation of the lining of the blood vessels by drugs during infusion. 2. It may also be caused by damage to the lining of the blood vessels due to external forces, which may occur including extrusion or impact. In the case of vascular inflammation, topical treatment can be used, including topical application of Xylitol or heparin sodium ointment, which can usually reduce inflammation and alleviate pain. Oral NSAIDs, such as ibuprofen or diclofenac sodium, can also be used to both reduce pain and promote better inflammation. At the same time, hot compresses or physical therapy can be used to improve local blood circulation for faster absorption of inflammation. In case of recurrent vascular inflammation, further investigations are performed to rule out conditions such as immune vasculitis or vasculitis.
