[Thromboembolic diseases from a haemostaseologic point of view]

Venous thromboembolism is one of the most common vascular diseases. Increased thrombin formation together with reduced blood flow create a hypercoagulable environment that induces thrombus formation. Anticoagulants play a pivotal role in the treatment and secondary prophylaxis of venous thromboembolism because they effectively interrupt this hypercoagulability. A personalized assessment of the thrombotic risk is essential for planning the duration and intensity of secondary prophylaxis. The occurrence of thrombosis outside a typical risk situation, an atypical localization and a family history of thrombosis indicate a thrombophilic state. In these cases, thrombophilia diagnostics are useful for extended risk assessment. If anti-phospholipid antibodies are detected, the risk of recurrence is particularly increased.
