Low-grade astrocytoma: surgical outcomes in eloquent versus non-eloquent brain areas

Low-grade astrocytoma: surgical outcomes in eloquent versus non-eloquent brain areas.

A retrospective study of 81 patients with low-grade astrocytoma (LGA) comparing the efficacy of aggressive versus less aggressive surgery in eloquent and non-eloquent brain areas was conducted. Extent of surgical resection was analyzed to assess overall survival (OS) and progression- free survival (PFS). Degree of tumor resection was classified as gross total resection (GTR), subtotal resection...

Surgical Strategies for Epilepsy in Eloquent Areas

As part of their initial workup, patients typically undergo videoelectroencephalography (video-EEG), magnetic resonance imaging (MRI) of the brain, and neuropsychological testing [3]. Depending on how well these tests localize the epileptic foci, additional studies might be indicated, such as positron emission tomography (PET), magnetoencephalography (MEG), and single photon-emission computed t...

Management of Brain Tumors in Eloquent Areas

Brain tumours in eloquent areas represent a great challenge for Neurosurgeons due to its surgical resection complexity. The main goal of this chapter is the comprehensive study of perioperative work-up, diagnostic and preoperative functional techniques, microsurgical skills and intraoperative monitoring for the management of brain tumours located in eloquent areas. Integral management of brain ...

Functional recovery after surgical resection of low grade gliomas in eloquent brain: hypothesis of brain compensation.

OBJECTIVES To describe functional recovery after surgical resection of low grade gliomas (LGG) in eloquent brain areas, and discuss the mechanisms of compensation. METHODS Seventy-seven right-handed patients without deficit were operated on for a LGG invading primary and/or secondary sensorimotor and/or language areas, as shown anatomically by pre-operative MRI and intraoperatively by electri...
