The subdural space: the third place to go astray
Anaesthesia, 1990Summary Subdural placement of the tip of the Tuohy needle or epidural catheter may account for many unexpected complications of attempted epidural blockade, for example ‘unexplained’ headache, false‐negative aspiration test down needle or catheter, false‐negative test dose, unilateral block, delayed total spinal and neurological ...

On the question of a subdural space
The Anatomical Record, 1991AbstractThe structure of the meninges, with particular attention to the architecture of the inner portions of the dura mater and the arachnoid mater, has been reviewed in reference to the probable existence of a “subdural” space. The dura is composed of fibroblasts and large amounts of extracellular collagen. The innermost part of the dura is formed by

Scanning in diseases of the subdural space
Seminars in Nuclear Medicine, 1971Hematoma, hygroma, and empyema, as well as primary or secondary neoplasm may occupy the subdural space and appear as a thickened vascular rim or "crescent sign" on the brain scan. In the evaluation of a patient for this differential diagnosis, it must also be considered that chronic subdural hematomas may be detected with greater ease than the acute or

The Origin of the Spinal Subdural Space: Ultrastructure Findings
Anesthesia & Analgesia, 2002Previous 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 Subdural Myth: Space or Place?
Anatomy & Physiology, 2016The term “Subdural” is commonly used loosely to describe any item below the Dura Mater, but when considering the mechanics of Shaken Baby Syndrome it is necessary to keep to the original definition of a space between the Dura Mater and the Arachnoid mater. In 1991, a survey of literature relating to the structure of the meninges found that 32 out of 42

Ultrastructure of Spinal Subdural Compartment: Origin of Spinal Subdural Space
2014The study of the structure of the subdural compartment is relevant in the performance of neuraxial blockade and in the understanding of the origin of cranial and spinal subdural hematomas associated with cerebrospinal fluid hypotension.

THE SUBDURAL SPACE AND ITS LININGS
Archives of Neurology And Psychiatry, 1933Since the monumental work of Key and Retzius 1 it has been generally accepted that the subdural space is lined by endothelium (mesothelium), as are the serous spaces. Mallory, 2 in 1920, asserted that the subdural space is not lined by endothelium, but by fibroblasts, the cells lining the dura being highly differentiated fibroblasts and those covering ...

[Does the subdural space exist?].
Revista espanola de anestesiologia y reanimacion, 1999A potential space between the dura mater and the arachnoides is thought to exist, occupied by a serous fluid and called the subdural space. Recent studies may change this classical concept, however. The dura-arachnoid complex from the epidural to the arachnoid space is formed by morphologically distinct layers: the dura mater, the subdural compartment ...

Tension Pneumocephalus of the Cranial Subdural Space
Neurosurgery, 1979Abstract A case of subdural tension pneumocephalus is presented. Computerized cranial tomography permitted rapid diagnosis including localization of the air, thus facilitating prompt treatment. Tension pneumocephalus should be considered in a patient with a cerebrospinal fluid drainage device who deteriorates after craniotomy.

The subdural space interpreted as a cellular layer of meninges
The Anatomical Record, 1991AbstractThe subdural region within the cranial meninges is examined in guinea pigs by electron microscopy. The fine structures of the arachnoid membrane and dura are described separately in specimens that have been isolated from each other during removal from the cranial cavity. In addition, the fine structure of the intact dura‐arachnoid is described,
