Moderate Recommendation	new 2023
General thrombophilia screening with the aim of reducing mortality or improving functional outcome cannot be recommended. In analogy to the procedure for lower-extremity deep vein thrombosis and pulmonary embolism, knowledge of thrombophilia can influence the decision on the type and duration of anticoagulation in individual cases and should therefore be considered preferably in young patients, in spontaneous CVT, in recurrent thrombosis and/or in patients with a positive family history of venous thromboembolism, and if therapeutic consequences can be derived from the result
