Congenital predisposition and VTE
There are three congenital disorders related to the appearance of a thrombosis and/or pulmonary embolism
Once VTE diagnosis is confirmed and the patient is stabilized, we have to find the cause of the disease, especially when VTE appears in young people or patients who do not have any risk factors that justifies it. Sometimes we discover that the patient has some type of congenital alteration which makes their blood more likely to clot, which tells us why a thrombosis occurred.Only few of this group of patients will have to take anticoagulants for life.
A person with a congenital predisposition to thrombosis must be aware of this and always inform their doctor when they need to undergo surgery, take estrogen drugs, or have to be immobilized
The main congenital disorders that are related to the appearance of VTE are:
- deficits of antithrombin, protein C or protein S
- genetic alterations such as the presence of Factor V Leiden and prothrombin 20210 gene mutation
- anti-phospholipid syndrome (which is not a congenital disease)
