Epidural space: Anatomy and function - Kenhub
2023年10月30日 · The term "epidural space" commonly denotes the area between the dura mater, the outermost layer of the spinal meninges, and the inner surface of the vertebral canal. However, the term is also used to describe the extradural space of the cranial cavity, which typically exists as a potential space.
Epidural space - Wikipedia
Between the vertebrae and the dural sheath is the spinal epidural space. Unlike the cranial epidural space, the spinal epidural space contains adipose tissue, the internal vertebral venous plexuses and the spinal nerve roots. [1]
Update on applied epidural anatomy - PMC - PubMed Central …
Applied anatomy for common approaches to the epidural space. The commonly used ‘loss of resistance’ technique to saline or air relies on a sudden, marked, loss of resistance to injection, between the dense ligamentous tissues and the looser, fat-filled epidural space.
It has been found that the morphogenesis of the primary epidural space is determined by the formative influence of the spinal cord and its dura mater, while that of the secondary epidural space is determined by the walls of the vertebral canal (Rodionov et al., 2010).
Anatomy of the epidural space - ScienceDirect
2012年11月1日 · The posterior longitudinal ligament (PLL) borders the epidural space anteriorly as it overlies the vertebral bodies and intervertebral discs. Laterally the medial aspect of the pedicles and the intervertebral foramina demarcate the space.
Epidural Space - an overview | ScienceDirect Topics
The epidural space between the dura and the bones of the spinal canal contains epidural fat, spinal nerves, blood vessels, and ligaments. The epidural fat space is prominent ventral to the dura at the mid-body level of the lumbar vertebrae, especially L5-S1 ( Fig. 3-26 ).
Recall relevant anatomy adjacent to the epidural space. Explain the role of ultrasound in identifying the epidural space when faced with challenging anatomy. A sound knowledge of applied anatomy is the cornerstone of safe and effective regional anaesthesia. In this update we revise the anatomy of the epidural space and relevant adja-
The posterior longitudinal ligament (PLL) borders the epidural space anteriorly as it overlies the vertebral bodies and interver-tebral discs. Laterally the medial aspect of the pedicles and the intervertebral foramina demarcate the space. The exact point within the foramina that the epidural space ends is not well defined.
Epidural space The boundaries of the epidural space are sum-marized in Table 1 and the definitions of the cervical, thoracic, lumbar and sacral regions are defined in Table 2. The epidural space contains fat, the dural sac, spinal nerves, blood vessels and connective tissue (Table 3). Blood supply Inside the spinal canal there is an anterior and
The anatomy of the epidural space - Anaesthesia & Intensive …
The epidural space is important to the anaesthetist as the site for epidural block. It surrounds the spinal part of the dura and extends from the foramen magnum of the skull to the sacral hiatus. It contains the vertebral plexus of veins, small arteries, lymphatics and the epidural fat.
