The choice of medication for slow cardiac reflux should be determined under the guidance of a doctor according to the specific cause of the disease and the patient’s individual situation, such as lower extremity venous thrombosis can be used to use urokinase and other drugs, such as lower extremity venous valvular insufficiency can be used to use drugs such as dioxygenin. Slow cardiac reflux can be seen in lower extremity deep vein thrombosis, lower extremity venous valve insufficiency, abdominal tumor compression of blood vessels resulting in venous reflux obstruction and other diseases. 1. In the case of lower extremity deep vein thrombosis, treatment includes medication (urokinase, streptokinase, etc.) and interventional surgery. If it is caused by venous valvular insufficiency of the lower limbs, the treatment can choose conservative treatment (wearing compression stockings, avoiding prolonged standing and sedentary activities), medication (Diosmin, Mazolin, etc.), injection of sclerosing agent, and surgical treatment if necessary. 2. If the slow blood return is caused by the compression of abdominal tumor, we need to carry out appropriate treatment for the tumor and release the vascular compression to relieve the problem. It is recommended to go to the hospital for further examination to clarify the cause of slow return, and to formulate a treatment plan under the guidance of specialized doctors.
