CAROTID ARTERY DISSECTION

 

Carotid artery dissection is a tear in the inner layer of the carotid artery wall that allows blood to flow between the layers. It can be caused by injury or occur suddenly without a known cause. https://people.com/mom-died-flight-from-dominican-republic-experienced-medical-tragedy-brother-says-8609170

Carotid artery dissection is the most common cause of stroke.

Symptoms:
  • Headache.
  • Scalp pain.
  • Eye pain.
  • Neck pain.
  • One eye with a droopy lid and small pupil (partial Horner syndrome)
  • One-sided weakness or numbness.
  • Pulsing sound in an ear.
  • Trouble swallowing.

      CAUSES:

An injury to the neck can cause carotid dissection. The injury may be caused by something like a car accident.

Some people with diseases that are known to weaken arterial walls are at greater risk for a dissection. These dissections can occur with vigorous physical activity such as:

  • Swimming and scuba diving
  • Skating and dancing
  • Play sports such as tennis, basketball, or volleyball
  • Doing yoga
  • Riding roller coasters or other rides
  • Jumping on a trampoline
  • Giving birth
  • Having sex
  • Sneezing or coughing
  • Receiving extreme neck manipulations

 A carotid dissection can also occur suddenly, without a known cause.

RISK factors:

  • Infection
  • High blood pressure
  • Migraine headaches
  • Smoking
  • An elongated styloid process
  • Use of birth control pills
  • Alcohol use
  • Fibromuscular dysplasia
  • Ehlers-Danlos syndrome
  • Marfan syndrome
  • Homocystinuria
  • Alpha-1 antitrypsin deficiency
  • Osteogenesis imperfecta
  • Cystic medial necrosis of the aorta
  • Segmental mediolytic arteriopathy
  • Reticular fiber deficiency
  • Reversible cerebral vasoconstriction syndrome
  • Autosomal dominant polycystic kidney disease

TESTING:

  • Lumbar puncture with analysis of cerebrospinal fluid
  • Magnetic resonance imaging (MRI) of the brain and neck
  • Magnetic resonance angiography (MRA) of the brain and neck
  • Cranial computed tomography (CT)
  • Cranial computed tomography angiography (CTA)
  • Carotid doppler and ultrasound

TREATMENT:

  • Clot-busters (thrombolytics), if your dissection caused a stroke
  • Heparin to prevent more blood clots
  • Intravenous (IV) fluids
  • Blood pressure medicine
  • Insulin or glucose to control your blood sugars
  • Pain medicines, such as acetaminophen, ibuprofen, or naproxen
  • Antiplatelet medicines, such as aspirin
  • Anticoagulant therapy with warfarin or other anticoagulation drugs
  • Surgery/Stent(s)

A carotid dissection can cause problems with blood flow to Brain or Eyes. This can cause a TIA, stroke, or one-sided blindness, which are Medical Emergencies. Call 911 if one be having a stroke or TIA or if there is sudden loss of vision.
