A venous thrombosis is one of several diseases caused by inappropriate blood clots (thrombi) in veins principally of the arms and legs; thromboses of the pulmonary vein or vena cava are outside the scope of this article. The major area of concern is deep venous thrombosis, although there is also superficial venous thrombosis.

## Deep venous thrombosis[edit]

For more information, see: Deep venous thrombosis.

## Ovarian vein thrombosis[edit]

Comparison of risk factors amoung women with ovarian vein thrombosis and deep venous thrombosis[1] | Ovarian vein thrombosis | Deep venous thrombosis

|
|

Increased estrogen state
(ERT, OBCP, pregnancy) | 34% | 9%
Pelvic infection | 23% | 1%
Abdominal surgery | 22% | 4%
Underlying cancer | 12% | 15%
Idiopathic | 3% | 21%

## Superficial venous thrombousis[edit]

### Prognosis[edit]

Superficial venous thrombosis can be associated with deep venous thrombosis and an accompanying deep venous thrombosis occurring simultaneously or later.[2][3]

### Treatment[edit]

"Prophylactic dose fondaparinux given for six weeks appears to be a valid therapeutic option for ST of the legs" according to a meta-analysis by the Cochrane Collaboration. [4]

"Fondaparinux at a dose of 2.5 mg once a day for 45 days was effective in the treatment of patients with acute, symptomatic superficial-vein thrombosis of the legs and did not have serious side effects" according to the CALISTOrandomized controlled trial. [5]
