Causes

Thrombophlebitis (another medical term is "White Leg") is related to a thrombus in the vein. Risk factors include prolonged sitting and disorders related to blood clotting. Specific disorders associated with thrombophlebitis include superficial thrombophlebitis (affects veins near the skin surface) and deep venous thrombosis (affects deeper, larger veins). Thrombophlebitis migrans can be a non-metastatic manifestation of malignancies such as pancreatic carcinoma (Trousseau sign of malignancy). .
[edit]Diagnosis

The health care provider makes the diagnosis primarily based on the appearance of the affected area. Frequent checks of the pulse, blood pressure, temperature, skin condition, and circulation may be required.
If the cause is not readily identifiable, tests may be performed to determine the cause, including the following:
Doppler ultrasound
Extremity arteriography
Blood coagulation studies
[edit]Prevention

Routine changing of intravenous (IV) lines helps to prevent phlebitis related to IV lines. See the specific disorders associated with thrombophlebitis for other preventive measures.
[edit]Treatment

For more specific recommendations, see the particular condition. In general, treatment may include the following:
Medications
analgesics (pain medications)
anticoagulants e.g. warfarin or heparin to prevent new clot formation
thrombolytics to dissolve an existing clot such as intravenous streptokinase.
nonsteroidal anti-inflammatory medications (NSAIDS) such as ibuprofen to reduce pain and inflammation
antibiotics (if infection is present) selection will usually depend with the causative agent.
Support stockings and wraps to reduce discomfort
The patient may be advised to do the following:
Elevate the affected area to reduce swelling.
Keep pressure off of the area to reduce pain and decrease the risk of further damage.
Apply moist heat to reduce inflammation and pain.
Surgical removal, stripping, or bypass of the vein is rarely needed but may be recommended in some situations.

1.thrombophlebitis- is caused by blood clot in the veins.
could be secondarly suppurated, but the primiry cause is the venous clot.could be b/c of venous injury or malig.

2.cavernous sinus thrombosis- is caused by infection( mainly from one of the sinuses or centeral face),needs immediate admition and iv antibiotics. a good ddx could be orbital cellulitis. venous clot is after the infection.



Cereberal venous thrombosis( due to hypercoagulabilty or nephrotic syndrome) could lead to stoke, b/c of the back pressure and edema.
