There is no such thing as the fastest treatment for venous thrombosis, which can be done by thrombolytic therapy, interventional therapy and surgical thrombolysis. 1. Thrombolytic therapy: For patients with acute venous thrombosis within 72 hours of the onset of thrombosis, intravenous thrombolytic therapy with drugs such as urokinase or streptokinase can be used. 2. Interventional therapy: Doctors use CT positioning, ultrasound, etc. to place interventional devices into the vein where thrombosis occurs and inject thrombolytic drugs or place stents, etc. to alleviate the condition, and pay attention to the prevention of infection after the operation. 2. Surgical removal of thrombus: For patients with deep vein thrombosis within 72 hours of the onset of the disease, surgical removal of the thrombus can be considered to relieve the disease and complications. After the operation, patients need to take medication or carry out life care as prescribed by the doctor in order to effectively promote the recovery. For symptoms such as pain and edema caused by old thrombus, vein stripping excision can be considered. Patients with venous thrombosis should go to the hospital in time and choose a suitable treatment plan under the guidance of the doctor.
