Labyrinthine Artery Thrombosis

Labyrinthine artery thrombosis occurs when the blood flow in the labyrinthine artery, responsible for inner ear function, is blocked by a clot. This can lead to various symptoms affecting balance and hearing.

Types of Labyrinthine Artery Thrombosis

There are two main types:

  1. Complete thrombosis: Complete blockage of the artery.
  2. Partial thrombosis: Partial blockage, which can lead to varying degrees of symptoms.

Causes of Labyrinthine Artery Thrombosis

Several factors can contribute:

  • Atherosclerosis: Build-up of plaque in arteries.
  • Trauma: Injury causing damage to the artery.
  • Hypercoagulable states: Conditions increasing blood clotting risk.

Symptoms of Labyrinthine Artery Thrombosis

Common symptoms include:

  • Vertigo: Feeling of dizziness or spinning.
  • Hearing loss: Partial or complete.
  • Tinnitus: Ringing in the ears.
  • Nausea and vomiting: Due to severe vertigo.

Diagnostic Tests

Medical professionals use various tests to diagnose:

  • MRI: Imaging to detect blood flow in the inner ear.
  • Audiometry: Hearing tests.
  • CT angiography: Detailed imaging of blood vessels.

Non-Pharmacological Treatments

These focus on symptom management:

  • Vestibular rehabilitation: Exercises to improve balance.
  • Hearing aids: Assistive devices for hearing loss.

Drugs

Medications may include:

  • Anticoagulants: To prevent further clotting.
  • Anti-vertigo medications: To alleviate vertigo symptoms.

Surgeries

In some cases, surgical interventions like:

  • Thrombectomy: Removal of the clot.
  • Stenting: Placement of a stent to keep the artery open.

Prevention

Steps to reduce the risk:

  • Managing cardiovascular health: Controlling blood pressure and cholesterol.
  • Avoiding trauma: Protecting the head and ears from injury.

When to See a Doctor

Immediate medical attention is necessary if experiencing:

  • Sudden hearing loss or vertigo.
  • Persistent dizziness with nausea or vomiting.
