Abstract:
Posterior fossa craniotomy is commonly performed for various pathologies. However, intra-cranial infection following craniotomy causes morbidity. Pseudomeningocele is one of the main complications following posterior fossa operation. This study aimed to test the hypothesis that the risk of intra-cranial infection is increased in patients who undergo posterior fossa craniotomy with pseudomeningocele compared with those without pseudomeningocele. We retrospectively analyzed the data of patients undergoing posterior fossa craniotomy for the management of neurological pathologies at our institute from 2011 to 2020. A total of 308 craniotomies were included, and the primary outcome of interest was the occurrence of intra-cranial infection. Standard statistical methods were used to explore associations between several parameters, including pseudomeningocele, intra-cranial infection, and wound leak. Of the 308 craniotomies, 41 (13.3%) developed intra-cranial infection and 59 (19.2%) involved pseudomeningocele. Of cases involving pseudomeningocele, 27 (45.8%) developed an intra-cranial infection compared with only 14 of 249 without pseudomeningocele (5.6%; p < 0.001). In the multi-variable analysis, pseudomeningocele was associated with intra-cranial infection (odds ratio [OR] 8.56; 95% confidence interval [CI] 3.145-23.299; p < 0.001) and wound leak (OR 91.339; 95% CI 10.437-799.364; p < 0.001). The findings indicate that patients undergoing posterior fossa craniotomy are at a greater risk of intra-cranial infection if there is pseudomeningocele after the operation.
Insights
Posterior fossa craniotomy patients with pseudomeningocele face a significantly higher risk of intracranial infection. This complication, often following surgery, warrants careful monitoring and management strategies.
Area of Science:
- Neurosurgery
- Infectious Disease
- Patient Outcomes
Background:
- Posterior fossa craniotomy is a common neurosurgical procedure.
- Intracranial infection is a serious complication following craniotomy.
- Pseudomeningocele is a frequent complication after posterior fossa surgery.
Purpose of the Study:
- To investigate the association between pseudomeningocele and the risk of intracranial infection after posterior fossa craniotomy.
- To test the hypothesis that pseudomeningocele increases intracranial infection risk.
Main Methods:
- Retrospective analysis of 308 posterior fossa craniotomies performed between 2011 and 2020.
- Primary outcome: occurrence of intracranial infection.
- Statistical analysis to assess the association between pseudomeningocele, intracranial infection, and wound leak.
Main Results:
- Intracranial infection occurred in 13.3% of patients; pseudomeningocele in 19.2%.
- Patients with pseudomeningocele had a 45.8% rate of intracranial infection versus 5.6% without (p < 0.001).
- Pseudomeningocele was significantly associated with intracranial infection (OR 8.56) and wound leak (OR 91.339).
Conclusions:
- Pseudomeningocele is a significant risk factor for intracranial infection post-posterior fossa craniotomy.
- The presence of pseudomeningocele substantially increases the likelihood of developing intracranial infection.
- Early detection and management of pseudomeningocele may be crucial in preventing intracranial infections.
