Foot thrombosis may be venous thrombosis or arterial thrombosis, which will recur after surgical treatment if no follow-up treatment is done, so follow-up treatment is needed to completely eliminate foot thrombosis. 1. Venous thrombosis: Since the venous blood vessels in the feet are thin, it is difficult for surgical instruments to reach them, and generally conservative treatment is mainly adopted, often using anticoagulant drugs, such as rivaroxaban, apixaban, warfarin, etc. During the treatment, activities of the legs should be reduced. During the treatment period, activities of the legs should be reduced to prevent serious complications such as pulmonary embolism caused by dislodgment of blood clots. 2. Arterial thrombosis: the arteries in the feet are small arteries, and the occurrence of thromboembolism is usually treated non-surgically, with thrombolytic and anticoagulant medications such as urokinase, streptokinase, heparin, aspirin, etc., which can help to dissolve the thrombus and prevent it from continuing to spread; or the use of vasodilating medications such as Phentolamine and Sodium Nitroprusside, etc., in accordance with the doctor’s instructions. Patients with thrombus in the foot should go to the hospital in time, complete the examination, and carry out targeted treatment in a timely manner after a clear diagnosis.
