Multicenter StudyRisk factors for neurosurgical intervention within 48 hours of admission for patients with mild traumatic brain injury and isolated subdural hematoma.
The objective was to identify demographic, clinical, and radiographic risk factors for neurosurgical intervention within 48 hours of admission in patients with mild traumatic brain injury and isolated subdural hematoma. ⋯ In the setting of mild traumatic brain injury with isolated subdural hematoma, radiographic risk factors were shown to be stronger than demographic and clinical variables in understanding future risk of neurosurgical intervention. These final radiographic risk factors should be considered in the creation of future prediction models and used to increase the efficiency of existing management guidelines.

Multicenter StudyA taxonomy for cerebellar cavernous malformations: subtypes of cerebellar lesions.
An anatomical taxonomy has been established to guide surgical approach selection for resecting brainstem and deep and superficial cerebral cavernous malformations (CMs). The authors propose a novel taxonomy for cerebellar CMs, introduce 6 distinct neuroanatomical subtypes, and assess their clinical outcomes. ⋯ Most cerebellar CMs are convexity lesions that do not require deep dissection. However, transsulcal and fissural approaches are used for those beneath the cerebellar surface to minimize tissue transgression and preserve associated function. Complete resection without any new deficit is accomplished in most patients. The proposed taxonomy for cerebellar CMs (suboccipital, tentorial, petrosal, vermian, tonsillar, and deep nuclear) guides the selection of craniotomy and approach to enhance patient safety and optimize neurological outcomes.
