Equilibrium and Balance01:15

Equilibrium and Balance

4.3K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

Veins of Head and Neck01:19

Veins of Head and Neck

1.0K
The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

The Vestibular System01:29

The Vestibular System

39.0K
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

Venous Return01:04

Venous Return

2.4K
The circulatory system plays a crucial role in ensuring the optimal functioning of the human body. One of its critical components is venous return - the process that completes the blood circulation cycle. This article will delve into the concept of venous return, how it works, and its significance to our health.
What is Venous Return?
Venous return refers to the rate at which blood flows back to the heart from the body's peripheral veins. It's an integral part of the circulatory system...

Forced Oscillations01:06

Forced Oscillations

6.5K
When an oscillator is forced with a periodic driving force, the motion may seem chaotic. The motions of such oscillators are known as transients. After the transients die out, the oscillator reaches a steady state, where the motion is periodic, and the displacement is determined.

Vascular Spasm01:16

Vascular Spasm

1.1K
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...

Summary
This summary is machine-generated.

Persistent oscillating vertigo (POV), including mal de débarquement syndrome (MdDS) and nonmotion POV (nmPOV), may stem from neck and thoracic outlet venous compression. Treatment relieving this compression significantly improved vertigo symptoms.

Area of Science:

  • Neurology
  • Vascular Medicine
  • Vestibular Disorders

Background:

  • Persistent oscillating vertigo (POV) encompasses mal de débarquement syndrome (MdDS) triggered by motion and nonmotion POV (nmPOV) from factors like neck injury.
  • Shared symptoms include rocking/swaying vertigo, headache, cognitive slowing, and fatigue, with unknown underlying pathology.
  • The study investigates a potential link between POV and extracranial venous compression.

Purpose of the Study:

  • To investigate the association between persistent oscillating vertigo (POV) and extracranial venous compression.
  • To present a case series demonstrating symptom relief following treatment of venous compression in the neck and thoracic outlet.

Main Methods:

  • A case series of patients diagnosed with MdDS and nmPOV were treated for extracranial venous compression.
  • Interventions included styloidectomy, stenting, neurotoxin injections, myotomy, and thoracic outlet decompression.
  • Catheter venography was used to assess dynamic obstruction and venous blood shunting.

Main Results:

  • POV was consistently associated with compression of the internal jugular vein (IJV) or subclavian vein at specific anatomical locations.
  • Compressions were often bilateral and occurred in tandem.
  • Unilateral decompression procedures significantly relieved POV symptoms.

Conclusions:

  • Oscillatory vertigo perceptions in MdDS and nmPOV may result from pulsations caused by venous outflow obstruction.
  • Impaired venous outflow and elevated venous pressure near the inner ear could continuously stimulate the vestibular system.
  • Treating venous compression offers a potential therapeutic strategy for persistent oscillating vertigo.
