Chiropractic May Help Carotid Sinus

How Can Chiropractors Treat Carotid Sinus?

Carotid SinusIn human anatomy, the carotid sinus is a dilated area at the base of the internal carotid artery just superior to the bifurcation of the internal carotid and external carotid at the level of the superior border of the thyroid cartilage. This is sensitive to pressure changes in the arterial blood at this level. And a rare cause of spontaneous syncopal attacks.

This is the reflex area of the carotid artery, consisting of various nerve receptors for bar regulation (pressure regulation of the body in sync to external conditions). And dilated the portion of one of the major arteries supplying blood to the head. A widened portion of the carotid artery where there are nerve endings sensitive to pressure; when they are stimulated, the heart is slowed, blood.The carotid is an important component of a neural control system responsible for heart rate and blood pressure homeostasis.

Carotid-Cavernous Sinus Fistula

What Is a Carotid-Cavernous Sinus Fistula?

A carotid-cavernous sinus fistula (CCF) is an abnormal connection between an artery in your neck and the network of veins at the back of your eye. These veins at the back of your eye transport blood from your face and brain back to your heart and are located in small spaces behind your eyes called cavernous sinuses. Sometimes an abnormal channel forms between these veins and one of the internal or external carotid arteries that run up each side of your neck.

A fistula can raise the pressure in your cavernous sinuses, which may compress the cranial nerves located around the cavernous sinuses. This compression may damage the nerve function, which is to control your eye movements. These cranial nerves also allow you to experience sensation in parts of your face and head. The increased pressure caused by the fistula can also affect the veins that drain your eye. This can cause symptoms such as eye swelling and abnormal vision.

Causes of Carotid-Cavernous Sinus Fistula

Direct CCFs are most often caused by an accident or injury that tears your carotid artery wall. Causes may include:

A patient with breast carcinoma metastatic to the neck and carotid is described in whom syncope with hypotension and bradycardia developed.

Carotid Sinus Hypersensitivity or Carotid Sinus Syndrome: Risks, Symptoms, Diagnosis, Treatment

Symptoms Of Carotid Sinus Hypersensitivity or Carotid Sinus Syndrome

Some Of The Symptoms Of Carotid Sinus Hypersensitivity or Carotid Sinus Syndrome Are:

  • Frequent dizziness episodes
  • Hypotension , Loss of muscle tone
  • Excessive scarring in neck area, Amnesia after an episode of loss of consciousness
  • Reduced heart rate, Sudden falls, especially in the elderly population.

Treatment for Carotid Sinus Hypersensitivity or Carotid Sinus Syndrome
Surgical procedures like denervation surgery and endarterectomy is done to correct carotid hypersensitivity. Anticoagulants like asprin or Plavix can be given to prevent blood clotting and the blood getting thickened.

Managing Carotid Sinus Hypersensitivity or Carotid Sinus Syndrome
Carotid Sinus Hypersensitivity or Carotid Sinus Syndrome can be managed by following some steps as mentioned below:

  • Avoid massaging the carotid sinus
  • Avoid wearing tight collars
  • Turn the head slowly
  • Need to be extra careful when shaving over this area so as not to stimulate the artery. See more here.

The massage of the carotid is contraindicated in patients with diseased carotid arteries because of the risk of cerebrovascular accident.

Performing Carotid Sinus Massage in Elderly Patients

Carotid sinus massage is indicated in the elderly patient who has a history of unexplained falls, loss of consciousness and presyncope, and in whom results of the cardiac and neurologic work-up have been inconclusive. Because syncopal episodes account for a large number of emergency department visits in the elderly, physicians should know how to perform this maneuver. O’Shea and Parry describe the protocol used in their clinic, which has about 3,000 new patients each year.

Absolute contraindications to massage include myocardial infarction, transient ischemic attack or stroke within the preceding three months. A history of ventricular fibrillation or tachycardia, or a previous adverse reaction to massage are also absolute contraindications. A relative contraindication is the presence of carotid bruits, which should be evaluated by Doppler ultrasonography before proceeding with massage. If the ultrasound shows stenosis or atheroma, the patient should understand the risks and benefits of the procedure.

Electrocardiography (ECG) and continuous blood pressure monitoring should occur with the patient supine for at least five minutes before the massage. Baseline systolic and diastolic blood pressure measurements and heart rate should be recorded. By convention, massage is first done on the right carotid sinus with the patient supine. Between the angle of the mandible and the superior border of the thyroid cartilage. Read full article here.

The Carotid Sinus Can Lower Blood Pressure

The massage of the carotid sinus is contraindicated in patients with diseased carotid arteries because of the risk of cerebrovascular accidents; in rare instances, carotid sinus massage may initiate ventricular tachycardia. This is an area located at a major intersection of arteries and nerve points, and each patient should be aware of this tiny hub of activity. Normal people, especially the elderly massage unilateral or bilateral carotid sinus can cause three kinds of reaction, which is equivalent to the clinical carotid sinus syndrome syncope type performance.

The carotid sinus is usually present and which play a role in the regulation of partial pressure of CO 2 and O 2 levels in the blood destined to supply the brain, and in the blood pressure inside these vessels. It has been hypothesized that the dilation of this serves to support pressure sensing, and slows the blood flow to reduce pulsatility to protect the brain if you have this carotid sinus it’s better to ask ideas from the experts or you may call us here: (619) 831-8777 for more information.
