DVT :What causes plhlebitis? How serious can it be?

Phlebitis is defined as " inflammation of a vein". Depending upon the type of vein, this condition can be either superficial or deep. Superficial phlebitis can be located on any part of the body and is usually due to skin injury, skin infection, insect bite, etc. Superficial phlebitis is not a serious condition and usually can be easily treated and cured by:
1. Wearing elastic bandage and active movements;
2. Taking non-steroid ant-inflammatory drugs (aspirin);
3. Local usage of balsams that contain heparin, and
4. Antibiotics (if there is infection).

Deep phlebitis is also called deep vein thrombosis (DVT) and is a very serious condition. Deep veins of the legs are usually affected by this disorder. DVT can be due to: immobilization of the body, large surgical interventions in the abdomen or pelvis, deep leg traumas (fractures), post natal delivery and some types of hematological and malignant disorders. DVT is a serious condition because it also invites possible complications such as lung embolia, posthrombotic syndrome and venous gangrene (all very serious complications). DVT is treated in a hospital with thrombolitic medications. Immobilization is absolutely necessary. Anticoagulant drugs are used for preventing recidivism, or recurrence.
