Fluid accumulation after surgery for syringomyelia may be related to the syringomyelia not being closed, exudate not being completely absorbed, postoperative infection, etc. It needs to be relieved by observation, medication (amoxicillin, etc.), and surgical treatment, depending on the cause of the disease. 1. Sphincter not closed: It is possible that the sheath was only removed or flipped during the surgery, and the sheath is still not completely closed. In this case, another surgery is needed, and the area can be ligated again about three months after the surgery. 2. Exudate not completely absorbed: If it is not long before the end of the operation, it may be normal fluid exudate, as the body gradually recovers, the exudate will be absorbed by the surrounding tissues, which usually takes about one month. This situation does not require special treatment, it will be absorbed by itself, but you should observe the absorption situation in time to avoid infection. 3. Postoperative infection: If the sterilization is not strict before the operation or the infection after the operation, it will also lead to the presence of effusion. It is necessary to timely anti-infection treatment, you can take oral cefixime, amoxicillin and other antibiotics. It is recommended that patients seek timely medical treatment, clear diagnosis, actively cooperate with the doctor’s treatment, not indiscriminate use of drugs.
