What are the clinical risk factors for recurrent venous thromboembolism after a symptomatic deep vein thrombosis?
Identifying clinical risk factors such as proximal DVT, cancer, and prior thromboembolic events can help stratify patients who may benefit from prolonged prophylactic anticoagulation.
The recurrence rate after a symptomatic DVT is high. Patients with proximal DVT, diagnosed cancer, short duration of oral anticoagulation therapy, or a history of thromboembolic events had a higher risk of recurrent events, while patients with postoperative DVT had a lower recurrence rate. This knowledge could help identify patients who might benefit most from prolonged prophylactic treatment in various risk situations.
