Resistant Pseudomeningocele following Craniotomy for Non-Traumatic Acute Intracranial Haematoma in Very Young Children: Report of Four Cases.

Background: The incidence of non-traumatic intracranial haemorrhage among neonates is less than among adults. However, the outcomes are generally poor, with high rates of morbidity and mortality. Non-traumatic intracranial haemorrhage can cause a sudden increase in intracranial pressure, requiring emergency craniotomy for evacuation. Methods: We report 4 cases following craniotomy for non-traumatic acute intracranial haematoma in very young children. The surgical technique and postoperative course are discussed, with emphasis on dural repair to avoid resistant pseudomeningocele. Results: Despite successful management of the acutely raised intracranial pressure, all patients afterwards developed tense pseudomeningoceles and required formal dural repair. This led to a change in institutional practice and modifications to the surgical technique. Conclusion: The authors highlight the postoperative occurrence of resistant pseudomeningoceles in young children after clot evacuations and leaving the dura open. They describe the surgical procedures to avoid these pseudomeningoceles. [ABSTRACT FROM AUTHOR]
