Die frühzeitige Diagnose und Therapie von tiefen Venenthrombosen vermindern das Risiko für eine Lungenembolie und ein postthrombotisches Syndrom. In diesem Beitrag wird erklärt, welche Schritte für die Diagnosestellung von Bedeutung sind und welche Ursachen der tiefen Venenthrombose zugrunde liegen können.
Abstract
Deep vein thrombosis usually manifests as leg or pelvic vein thrombosis (DVT). The causes are either acquired or inherited and can also occur in combination. Early diagnosis and treatment of DVT can reduce the risk of pulmonary embolism and postthrombotic syndrome. The estimation of the clinical probability, if necessary in combination with the D-dimer test, points the way to further imaging diagnostics. After diagnosis, risk factors that led to the occurrence of thrombosis can be identified in many cases. In more than half of the cases, genetic causes play a role. If the cause is not clear, tumor screening should be performed, since up to 20 % of thromboses are due to tumor disease.
