Summary
Spinal cord vascular malformations, including arteriovenous malformations and cavernomas, are classified by imaging and histology. Magnetic resonance imaging aids diagnosis, often obviating angiography for these rare conditions.
Area of Science:
- Neurology
- Radiology
- Pathology
Context:
- Spinal cord vascular malformations present diagnostic challenges.
- Classification systems are crucial for understanding these lesions.
- Radiological and histological features guide diagnosis.
Purpose:
- To classify spinal cord vascular malformations based on radiological and histological findings.
- To highlight the diagnostic utility of Magnetic Resonance Imaging (MRI).
- To discuss the relative frequencies of different malformation types.
Summary:
- Spinal cord vascular malformations are categorized into arteriovenous malformations (AVMs), cavernomas, arterial aneurysms, and venous malformations.
- AVMs are the most common, including dural arteriovenous fistulas and intradural AVMs.
- Intradural cavernomas, arterial aneurysms, and venous malformations are rarer, with specific considerations for their location and presentation.
Impact:
- Provides a structured classification for spinal cord vascular malformations.
- Emphasizes the diagnostic role of MRI, potentially reducing the need for invasive angiography.
- Enhances understanding of the prevalence and characteristics of various spinal vascular lesions.

01:54The Spinal Cord
32.5K
The spinal cord is the body’s major nerve tract of the central nervous system, communicating afferent sensory information from the periphery to the brain and efferent motor information from the brain to the body. The human spinal cord extends from the hole at the base of the skull, or foramen magnum, to the level of the first or second lumbar vertebra.

01:30Neurulation
46.7K
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the...

01:26Varicose Veins I: Introduction
281
Varicose veins, or varicosities, are abnormally dilated and twisted superficial veins caused by venous valve incompetence. This condition commonly affects the lower extremities, especially the saphenous veins, due to the higher pressure from prolonged standing and walking. However, varicosities can also occur in other areas, such as the esophagus, vulva, spermatic cords, and anorectal region.Etiology and typesPrimary varicose veins, often idiopathic, are more common in women due to inherent...

5.6K
The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.

6.7K
The spinal cord resides within the protective confines of the vertebral column. It is the main pathway for information traveling between the brain and the body. It plays a fundamental role in nearly all bodily functions, from simple reflexes to complex motor movements. The spinal cord begins at the medulla oblongata at the base of the brainstem and extends downward, terminating at the conus medullaris near the first and second lumbar vertebrae. The spinal cord's length in adults is...

01:16Vascular Spasm
4.3K
The vascular phase, also known as vasospasm, is the initial stage of hemostasis, crucial for preventing excessive bleeding when a blood vessel is injured. After a vessel is cut, nerves in the damaged area trigger pain and other sensory impulses. Simultaneously, the smooth muscles in the vessel wall contract, resulting in a vascular spasm. This contraction reduces the vessel's diameter at the injury site, slowing or stopping blood loss through the vessel wall. Vascular spasms typically last...
