Minute Hæmorrhages in the Pia Mater

Diffuse Sarcoma of the Cerebral and Spinal Pia Mater

Tumors of the soft membranes of the brain and spinal cord, especially those of a diffuse character, are comparatively rare~ and a careflll study of each individual example is of distinct value. The dollowing case was kindly offered me for study by Prof. Ludvig ttektoen, to whom I am indebted for much assistance in the preparation of my report. Primary tumor of cerebrum, secondary diffuse sarcom...

Ultrastructural findings in human spinal pia mater in relation to subarachnoid anesthesia.

UNLABELLED We examined ultrastructural details such as the cellular component and membrane thickness of human spinal pia mater with the aim of determining whether fenestrations are present. We hypothesized that pia mater is not a continuous membrane but, instead, that there are fenestrations across the pial cellular membrane. The lumbar dural sac from 7 fresh human cadavers was removed, and sam...

Pia Mater Significantly Contributes to Spinal Cord Intraparenchymal Pressure in a Simulated Model of Edema.

STUDY DESIGN Intraparenchymal pressure (IPP) measurements in an in vitro cadaveric model of CNS edema. OBJECTIVE To assess the contribution of pia mater to IPP and the effect of piotomy. SUMMARY OF BACKGROUND DATA Multicenter randomized control trials have shown that decompression with durotomy/duroplasty significantly decreases intracranial pressure (ICP). There is a paucity of evidence re...

The retinopial vein: a vein passing directly from the retina to the pia mater at the optic nerve head.

BACKGROUND/AIMS All blood drainage from the retina is thought to occur through the central retinal vein with rare, if any, exceptions. A chance observation of a specimen in which this pattern did not apply suggested that the subject required review. METHODS An optic nerve head, identified from an earlier study as possessing an unconventional venous drainage arrangement, was examined histologi...
