Other thrombosis

Although thrombosis usually occurs in the leg, it may also appear in the arm, abdomen, brain or eye

Blood does not clot only in the deep veins of the legs. Thiscan also occur in the deep veins of the arms, in the veins of the abdomen and in the surface veins on arms or legs.

The most frequent place is a thrombosis of deep veins in the arms. The ratio is one case of DVT in an arm for every 30 cases of DVT in a leg, although DVT frequency in the arms has recently doubled due to an increasing use of intravenous catheters.

The symptoms are the same, but the risk of a pulmonary embolism is lower. The treatment is the same, and the long-term effects (pain, swelling, cramps) are also less frequent. A venous ulcer is rare.

Abdominal thrombosis

Thrombosis in the portal vein (carrying blood to the liver), of the mesenteric vein (collecting the blood from the intestine), of the splenetic vein (of the spleen) and of the renal vein is less common.

Sometimes these thromboses are diagnosed in patients who come to hospital suffering from abdominal pain, with nausea and vomiting or diarrhea. In other cases,  these types of thromboses are casual findings in patients without symptoms.

Retinal thrombosis

Retinal vein thrombosis is also rare. It usually presents as a sudden partial or total loss of vision in one eye.

Unlike the above, retinal venous thrombosis is not treated with anticoagulants
