objective: an assessment of  nonoperative and operative intervention in regards  to  neurological  improvement  following  traumatic  closed  cervical spinal cord injury (csci). method: a retrospective evaluation of a cohort of patients with a csci from c3 to t1 was reviewed. the analysis included a total of 13 eligible patients. the  neurologic  and  functional outcomes  were  recorded  from  ...

Reported are a total of 81 microsurgical operations for cranial nerve root decompression comprising of 66 trigeminal, 10 facial, one vestibular, one vagus and three accessory nerve dysfunction syndromes from 1983 to 1990. Almost all cases of trigeminal neuralgia (TNG) secondary to vascular (59 cases) and minute mass (10 cases) compression, and those with hemifacial spasm (HFS) (nine out o...

Epidermoid cysts are notorious for their propensity to sneak into deep recesses between cranial nerves in the posterior fossa. Attempts to achieve complete excision using ordinary instruments when tempted by the seeming ease of dissection is known to cause unacceptable deficits. The Xomed monopolar stimulator electrode probe of the nerve integrity electromyography monitor has several advantages...

Aneurysmal subarachnoid hemorrhage (SAH) has devastating consequences on brain function including profound effects on communication between neurons and the vasculature leading to cerebral ischemia. Physiologically, neurovascular coupling represents a focal increase in cerebral blood flow to meet increased metabolic demand of neurons within active regions of the brain. Neurovascular coupling is ...

BACKGROUND Heritable disorders of connective tissue are recognized in a small minority of patients with neurovascular diseases. In this report, we review the neurovascular manifestations of four heritable connective tissue disorders: Ehlers-Danlos syndrome, Marfan's syndrome, osteogenesis imperfecta, and pseudoxanthoma elasticum, as well as two other systemic disorders with potential vascular m...

Neural activity is intimately tied to blood flow in the brain. This coupling is specific enough in space and time that modern imaging methods use local hemodynamics as a measure of brain activity. In this review, we discuss recent evidence indicating that neuronal activity is coupled to local blood flow changes through an intermediary, the astrocyte. We highlight unresolved issues regarding the...
