Objective: Due to the particularity of anatomy, there are many subcutaneous effusions after posterior fossa surgery. This paper discusses the characteristics and treatment strategies of persistent infection related to subcutaneous effusions in the posterior fossa.
Methods: Seventeen patients with persistent intracranial infection after neurosurgical posterior fossa surgery from March 2015 to July 2020 were retrospectively analyzed. According to different stages of infection, the treatment process of intracranial infection was divided into the acute infection stage, clinical response stage and infection cure stage, and the measures taken in the different stages were summarized.
Results: Compared with the acute infection stage, the indices of body temperature, blood and cerebrospinal fluid in the clinical response stage were improved, but there was no significant difference. There was a significant difference in each index between the acute infection stage and the infection cure stage. After the infection was cured, 17 patients were significantly relieved or cured of subcutaneous effusions by various methods.
Conclusion: It is necessary to be alert to the existence of subcutaneous effusions in cases of poor effects or repeated infections after routine treatment. Multiple replacements and flushing of subcutaneous effusions are an important means of treating this kind of infection.
