We do not know about venous inflammatory disease, but the occurrence of this disease will be a lot of harm, will cause the patient\'s blood vessels to be damaged, but also cause blood vessel blockage. Patients need reasonable treatment, so as not to cause damage, causing the body to be oppressed, then, what are the common causes of phlebitis?

First, blood vessel wall damage: Blood vessel damage will cause platelet aggregation, fibrin and blood cell deposition, and promote thrombosis

Second, blockage of blood flow: long-term bed, sitting, squatting, will cause lower limb blood vessels to be squeezed, resulting in slow blood flow, stagnation, causing phlebitis.

Third, long-term infusion: continuous infusion through the catheter can cause direct damage to the vein wall, or damage the vein wall due to various mechanical impact reasons, resulting in inflammation.

Fourth, varicose veins: lower extremity varicose veins can lead to venous blood stasis, cause nutritional changes and chronic infection, so that varicose veins hypoxia, inflammation, the formation of phlebitis.

5, high blood concentration: lower extremity trauma, surgery, large area burns, pregnancy and postpartum, platelet increase, while the release of clotting factors, so that the blood composition changes, a hypercoagulable state, providing a hotbed for the formation of phlebitis.
