OBJECT Currently, mannitol is the recommended first choice for a hyperosmolar agent for use in patients with elevated intracranial pressure (ICP). Some authors have argued that hypertonic saline (HTS) might be a more effective agent; however, there is no consensus as to appropriate indications for use, the best concentration, and the best method of(More)
The dura mater is important to the clinician as a barrier to the internal environment of the brain, and surgically, its anatomy should be well known to the neurosurgeon and clinician who interpret imaging. The medical literature was reviewed in regard to the morphology and embryology of specifically, the intracranial dura mater. A historic review of this(More)
Liliequist’s membrane is an arachnoid membrane that forms a barrier within the basilar cisternal complex. This structure is an important landmark in approaches to the sellar and parasellar regions. The importance of this membrane was largely recognized after the advance of neuroendoscopic techniques. Many studies were, thereafter, published reporting(More)
The intracranial bridging veins are pathways crucial for venous drainage of the brain. They are not only involved in pathological conditions but also serve as important landmarks within neurological surgery. The medical literature on bridging veins was reviewed in regard to their historical aspects, embryology, histology, anatomy, and surgery. Knowledge on(More)
INTRODUCTION Entrapment of the suprascapular nerve at the suprascapular notch may be due to an ossified suprascapular ligament. The present study was conducted in order to investigate the incidence of this anomaly and to analyze the resultant bony foramen (foramen scapula) for gross nerve compression. MATERIALS AND METHODS We evaluated 104 human scapulae(More)
Masses of the lateral skull are not uncommon and include lipomas and epidermoids. However, meningoceles of the lateral skull are very rare and are often misdiagnosed. Even rarer are atretic encephaloceles of this region. We report a newborn with a right atretic encephalocele of the asterion. Lesions of the anterolateral and posterolateral fontanelles should(More)
OBJECT Knowledge of the detailed anatomy of the craniocervical junction is important to neurosurgeons. To the authors' knowledge, no study has addressed the detailed anatomy of the intracranial (first) denticulate ligament and its intracranial course and relationships. METHODS In 10 embalmed and 5 unembalmed adult cadavers, the authors performed posterior(More)
Alfred W. Adson was a pioneer in the field of neurosurgery. He described operations for a variety of neurosurgical diseases and developed surgical instruments. Under his leadership the Section of Neurological Surgery at the Mayo Clinic was established and he functioned as its first chair. Adson's contributions to the understanding of spinal and spinal cord(More)
BACKGROUND The resection of planum sphenoidale and tuberculum sellae meningiomas is challenging. A universally accepted classification system predicting surgical risk and outcome is still lacking. OBJECTIVES We report a modern surgical technique specific for planum sphenoidale and tuberculum sellae meningiomas with associated outcome. A new classification(More)
Spinal cord injury is a highly prevalent condition associated with significant morbidity and mortality. The pathophysiology underlying it is extraordinarily complex and still not completely understood. We performed a comprehensive literature review of the pathophysiologic processes underlying spinal cord injury. The mechanisms underlying primary and(More)
