Conservative treatment should be considered first for senile venous thrombosis, and surgery can be considered if the effect is not good. 1. Conservative treatment: venous thrombosis in the elderly is mainly lower extremity venous thrombosis. Considering the tolerance level of the elderly, it is generally recommended to take bed rest, elevate the affected lower limb, limit the activity of the affected limb, and then get down from the bed after the pain is relieved, as recommended by the doctor, in order to prevent pulmonary embolism. Anti-coagulation and thrombolytic therapy should also be carried out, and commonly used drugs include heparin and streptokinase. 2. Surgery: However, if the effect of conservative treatment such as anticoagulation and thrombolysis is unsatisfactory, and the condition aggravates acutely, it is necessary to consider surgical treatment to remove the thrombus. It should be noted that if venous thrombosis in the elderly is not actively treated, it is easy to cause pulmonary embolism and other complications, which has a serious impact on the quality of life, and it is recommended to cooperate with doctors for proper treatment.
