Insights

Dorsal thoracic arachnoid webs are a rare cause of spinal cord compression. This video shows microsurgical resection of a dorsal arachnoid band, relieving progressive myelopathy.

Area of Science:

  • Neurosurgery
  • Spinal Surgery
  • Neurology

Background:

  • Dorsal thoracic arachnoid webs are an uncommon cause of progressive myelopathy.
  • Associated syringomyelia may occur above or below the arachnoid band.
  • Differential diagnoses include dorsal arachnoid cysts and ventral spinal cord herniation.

Observation:

  • A 63-year-old man presented with progressive myelopathy.
  • Microsurgical techniques were employed for identification and resection.
  • The condition was caused by a dorsal arachnoid band compressing the spinal cord.

Findings:

  • Successful microsurgical resection of the dorsal arachnoid band was performed.
  • The procedure aimed to decompress the spinal cord.
  • Visual documentation of the surgical technique is provided.

Implications:

  • This video demonstrates a viable surgical approach for dorsal thoracic arachnoid webs.
  • Early diagnosis and surgical intervention can prevent further neurological decline.
  • Microsurgical resection offers a potential solution for myelopathy caused by these rare spinal anomalies.

Cranial and Spinal Meninges01:19

Cranial and Spinal Meninges

The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

Spinal Cord: Gross Anatomy01:15

Spinal Cord: Gross Anatomy

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...

Anatomy of the Brain: Ventricles

There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen.

Cerebrospinal Fluid01:21

Cerebrospinal Fluid

Cerebrospinal fluid (CSF) is a colorless liquid that flows around the brain and the spinal cord, playing a vital role in the protection, support, and overall function of the central nervous system (CNS). CSF production, circulation, and absorption are tightly regulated processes essential for the brain and spinal cord to function properly.
CSF Production
CSF is produced mainly in the choroid plexus, a network of capillaries and ependymal cells located within the ventricular system of the brain....

Spinal Cord: Cross-sectional Anatomy

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.
Gray Matter and its Components
Central to the gray matter is...

The Arch of Aorta01:10

The Arch of Aorta

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
Encircling the heart, the coronary arteries form a ring-like structure before...
