Carotid Artery Disease

Content

Carotid artery disease may be asymptomatic (without symptoms) or symptomatic (with symptoms). Asymptomatic carotid disease is the presence of a significant amount of atherosclerotic build-up without obstructing enough blood flow to cause symptoms. However, a sufficiently tight stenosis will not always cause symptoms. Symptomatic carotid artery disease may result in either a transient ischemic attack (TIA) and/or a stroke (brain attack).

A transient ischemic attack (TIA) is a sudden or a temporary loss of blood flow to an area of the brain, usually lasting a few minutes to one hour. Symptoms usually go away entirely within 24 hours, with complete recovery. Symptoms of a TIA may include, but are not limited to, the following:

  • Sudden weakness or clumsiness of an arm and/or leg on one side of the body
  • Sudden paralysis (inability to move) of an arm and/or leg on one side of the body
  • Loss of coordination or movement
  • Confusion, dizziness, fainting, and/or headache
  • Numbness or loss of sensation (feeling) in the face
  • Numbness or loss of sensation in an arm and/or leg
  • Temporary loss of vision or blurred vision
  • Inability to speak clearly or slurred speech

    • TIA may be related to severe narrowing or blockage or from small pieces of an atherosclerotic plaque breaking off, traveling through the bloodstream, and lodging in small blood vessels in the brain. With TIA, there is rarely permanent brain damage.

    Call for medical help immediately if you suspect a person is having a TIA, as it may be a warning sign that a stroke is about to occur. Not all strokes, however, are preceded by TIAs.

    Stroke is another indicator of carotid artery disease. The symptoms of a stroke are the same as for a TIA. A stroke is loss of blood flow (ischemia) to the brain that continues long enough to cause permanent brain damage. Brain cells begin to die after just a few minutes without oxygen. The area of dead cells in tissues is called an infarct.

    The area of the brain that suffered the loss of blood flow will determine what the physical or mental disability may be. This may include impaired ability with movement, speech, thinking and memory, bowel and bladder function, eating, emotional control, and other vital body functions. Recovery from the specific ability affected depends on the size and location of the stroke. A stroke may result in problems such as weakness in an arm or leg or may cause paralysis, loss of speech, or even death.

    The symptoms of carotid artery disease may resemble other medical conditions or problems. Always consult your physician for a diagnosis.


    Carotid Stenosis

    Content

    The goal of treatment for carotid artery disease is to reduce the possibility of TIA or stroke, or to prevent the recurrence of a stroke.

    Medical Therapy - Medications such as aspirin, other antiplatelets agents (like Plavix), diabetic medications, and medications that lower cholesterol and blood pressure are commonly prescribed when the degree of narrowing is less than 60 percent. Smoking cessation, exercise, and a healthy diet is also important for managing carotid artery disease and preventing further narrowing.

    Carotid Endarterectomy - For patients with significant carotid artery narrowing with or without stroke-like symptoms, surgery may be recommended. Carotid Endarterectomy surgery involves exposing the carotid artery in the neck, clamping the artery above and below the plaque buildup, opening up the artery with a knife while it is clamped and directly removing the plaque (Figure 2).

    Carotid Stenting - Alternatively, for select patients, carotid angioplasty and stenting, may be recommended. This procedure involves placing a self-expanding stent in the artery at the site of the narrowing and the stent expands holding the artery open (Figure 3), thereby, reducing the risk of future strokes.


    Georgia Stroke Care Provider Hangs On To Medical Malpractice Win

    A Georgia doctor won't face a new trial over claims that he negligently treated carotid artery disease in a patient who suffered a series of small strokes before a debilitating post-surgery event that led to her death.

    The health-care providers' expert witness was qualified to testify about the standard of care and whether it was breached, even though she was relatively inexperienced compared to the defendant, the Georgia Court of Appeals said Aug. 2 in affirming the judgment. Two non-pattern jury instructions, moreover, didn't improperly placed "a thumb on the scale" in the defendants' favor, the court said.

    Real Stories From People Who Had a Surprising Gut Feeling That Turned Out to Be Correct - Obsev

    Some people claim to have a sixth sense that lets them know when something is about to happen. Although most people aren't clairvoyant, there is some truth to having a gut feeling about future events. People have claimed to turn down job offers, decline evening plans and forgo vacations just because they had a feeling that things were about to take a turn for the worse. And when these feelings prove to be right, it's evident that maybe there is a reason that people have these instincts. The gut wrenching feeling that you have to act now just can't be ignored. Having a life-threatening experience is memorable enough, but narrowly avoiding one by seconds is just as unforgettable.   He's Still in Jail Unsplash My oldest daughter (30-something) stopped by my work one day and introduced her new boyfriend.

    clinical trials day :: Article Creator Everyday Drug Discovery: How Tech Expands The Potential Of Clinical Trials And Recentres Participants Throughout my career in the development and implementation of technological solutions to support clinical research, I've been lucky enough to work closely with a wide range of so-called "stakeholders" in the clinical trial lifecycle, from regulators, drug development research teams, site staff, and patients.  While all groups have demonstrated an inspiring level of dedication and passion, I have always been moved by patients' willingness to sacrifice their time and adapt their care plans to take part in clinical trials, fully understanding they might not directly benefit from the treatment being tested, though so often desperately hoping they do. Patients recognise the importance of clinical research to the long term success in treating diseases of all kinds, and in turn the industry has t...
