In 1909 Thomas Jonnesco published his interesting paper under the title General spinal anesthesia through an approach of the subarachnoid space at a thoracic level, providing condition for surgery on the skull, head, neck and thorax. Etherington-Wilson proposed explaining the various possibilities for the spinal anesthesia. Leonardo da Vinci was considered the discoverer of Human and animal Ana...

Abundant erythrocytes remain and lyse partially in the subarachnoid space after severe subarachnoid haemorrhage (SAH). But the effect of subarachnoid erythrocyte lysate on brain injury is still not completely clear. In this study, autologous erythrocytes (the non-lysate group) and their lysate (the lysate group) were injected separately into the cistern magna of rabbits to induce a model of exp...

Subarachnoid pharmacotherapy, a novel therapeutic strategy for the treatment of focal neocortical epilepsy, could be adapted for the treatment of stroke. Specifically, subarachnoid pharmacotherapy could be adapted to maximize functional recovery after cortical ischemic stroke. The key element of this strategy is a device implanted chronically in the subarachnoid space overlaying the cortical in...

background developing controlled hypercarbia is a known scheme of lowering the suprasellar part of the adenoma in order to assist the surgeon, which acts through raising the icp and therefore the csf pressure. objectives the purpose of this study is to compare the effect of introducing a lumbar drain with that of controlled hypercapnia on the quality of transsphenoidal pituitary tumor resection...

While a wide array of pathological changes occur in cerebral arteries following subarachnoid hemorrhage (SAH), the most consistent is endothelial damage. Since the endothelium normally modulates reflexes that influence vascular tone, any damage to it may represent a significant contributor to cerebral vasospasm following SAH. This experimental study investigates the correlation between end...

The result of the recent survey regarding cervical myelography by using a C1–2 puncture published by Yousem and Gujar is an important contribution to the neuroradiologic practice. The authors’ excellent work demonstrates the rationale in an effort to maintain the existing skills, even requiring certain skills. For a long time, we have practiced the lateral cervical approach with intrathecal pun...

OBJECTIVE To apply a theoretical model to analyse the derangement of cerebrospinal fluid (CSF) dynamics in syringomyelia associated with adhesive arachnoiditis. METHODS An electrical circuit model of CSF dynamics in the spine was used. With this model, the derangement of CSF dynamics in adhesive arachnoiditis was simulated. The effects of various surgical procedures were then analysed, such a...
