After spinal bulge surgery, children are warned to become “big-headed dolls” After spinal bulge surgery, hydrocephalus is very rare, but usually, cervicothoracic spinal bulge surgery may occur, or the child was already combined with hydrocephalus, if not treated in a timely manner, the child’s head will be the cerebrospinal fluid to expand, becoming ” Big head doll”. Cerebrospinal fluid is a colorless, clear liquid that circulates in the spinal canal and the brain. This circulatory system forms a cushion of water, like amniotic fluid, that protects the spinal cord and brain tissue from direct contact with the skull during a shock. If the cerebrospinal fluid circulation channels are not smooth, or if too much cerebrospinal fluid is produced and too little is absorbed, hydrocephalus will accumulate in the brain. Generally speaking, in children with hydrocephalus after surgery, if the condition is not too serious, then three months after the spinal bulge surgery, you can do hydrocephalus shunt surgery again to drain part of the cerebrospinal fluid into the abdominal cavity, so that the abdominal cavity can absorb the excess cerebrospinal fluid and avoid compression of the spinal cord and brain tissue; however, if the hydrocephalus is acute and the intracranial pressure increases sharply, you cannot wait too long, but have to do external drainage directly to drain the cerebrospinal fluid However, in the case of acute hydrocephalus, the intracranial pressure increases dramatically, so we cannot wait too long. For children who may have hydrocephalus before surgery, if the hydrocephalus is not severe, or if the pressure on the spinal cord and cranial brain is not too severe, then spinal bulge surgery can be done first; if the hydrocephalus is severe before surgery, then the hydrocephalus must be treated first, and then the spinal bulge. After spinal bulge surgery, the wound runs clear water. Be alert for cerebrospinal fluid leakage. In addition to hydrocephalus, more attention should be paid to cerebrospinal fluid leakage after surgery. The spinal cord is in the subarachnoid space of the spinal canal and is infiltrated by cerebrospinal fluid. If the lesion is not repaired well enough, when the cerebrospinal fluid pressure increases, it will leak out of the wound and flow out a clear water-like substance. This not only makes it difficult for the wound to heal, but in more serious cases, it may also cause cerebrospinal fluid infection and consequently central nervous system infection, such as meningitis and intracranial infection. Therefore, it is important to repair the fistula in a timely manner.
