Cerebrospinal fluid leakage in one year of lumbar spine surgery may be a complication that exists after lumbar spine surgery, which can be relieved by conservative and surgical treatments depending on the severity of the cerebrospinal fluid leakage and the infection. 1. Mild cerebrospinal fluid leakage: conventional conservative treatment can be carried out. Patients should pay strict attention to bed rest, immobilization and braking, and apply pressure bandage to the area with cerebrospinal fluid leakage. Positional drainage can also be adopted, i.e. by elevating the end of the bed, so that the upper part of the body is in a more downward part, which can reduce the leakage and facilitate the gradual closure. 2. Severe cerebrospinal fluid leakage: if the effect of conventional conservative treatment is not good, surgery should be carried out as soon as possible, and dural repair surgery can be taken to seal the leaking area. 3. Cerebrospinal fluid infection: If cerebrospinal fluid infection occurs, relevant debridement, cerebrospinal fluid puncture drainage and other surgical treatments can be carried out, and for the infection, broad-spectrum antibiotics such as cephalosporin can be selected for treatment. It is recommended to use medication under the guidance of a doctor, not blindly self-medication, in order to avoid adverse effects. If the above symptoms occur, it is recommended to go to the hospital in a timely manner, and early formal treatment.
