UNLABELLED Previous studies of samples from cranial meninges have created doubts about the existence of a virtual subdural space. We examined the ultrastructure of spinal meninges from three human cadavers immediately after death to see whether there is a virtual subdural space at this level. The arachnoid mater had two portions: a compact laminar portion covering the dural sac internal surface...

Meningiomas are common spinal tumor and mostly located at intradura. Recurrence rate after surgery for extradural meningioma was higher than intradural meningioma. A patient with intra and extradural spinal meningioma was treated and discussed its features and clinical management. A 41-year-old woman noted numbness of bilateral legs, gait disturbance, and mild bladder disturbance for over the t...

A case of myelomatous involvement of the dura mater is reported. The patient presented with blurring of vision in the right visual field and left sided facial numbness. A magnetic resonance imaging scan of the head revealed extensive infiltration of the dura mater. Cerebrospinal fluid (CSF) analysis showed no plasmacytosis and although there was a raised CSF protein concentration, no paraprotei...

An in vitro experimental study of the control of the human dura mater optical properties at administration of aqueous solutions of glucose and mannitol has been presented. The significant increase of the dura mater optical transmittance under action of immersion liquids has been demonstrated. Diffusion coefficients of glucose and mannitol in the human dura mater tissue at 20 degrees C have been...

The purpose of this researchanalyzed the determinants oil palm FFB yield on each character coastal land and mineral in eastern region Aceh Province based variety harvest fraction. Research has been carried out using survey methods experiments laboratories with36 samples were taken for three parts which would be used as a repeat determining CPO fatty acids from FFB. results showed that was deter...

The connective tissue attachments to the cervical spinal dura mater originating from the ligamentum nuchae (LN) and rectus capitis posterior minor (RCPM) muscle were evaluated in 30 cadaveric spines. Magnetic resonance images (MRIs) were correlated with the attachments in four cadaveric specimens. Attachments from the LN to the RCPM were also identified. The LN and the RCPM to dura attachments ...

This study was to evaluate the morphological features of degenerative spinal stenosis and adequacy of lateral canal stenosis decompression via unilateral and bilateral laminectomy. Measurements of facet joint angulation (FJA), mid facet point (MFP), mid facet point distance (MFPD), the narrowest point of the lateral spinal canal (NPLC) and the narrowest point of the lateral spinal canal distanc...

Neurosurgical Division of the Hospital Geral Santa Isabel, João Pessoa PB, Brazil;Associated Physician. The true importance of performing a watertight dural closure, for neurological procedures, is to avoid several complications such as cerebrospinal fluid (CSF) leakage, pseudomeningocele (PSM), meningitis, cerebral abscess, tonsilar herniation, hydrocephalus, etc. A variety of materials has be...
