vertebral column, arteries, the brain, vertebrobasilar insufficiency, posterior circulation ischemia, vertebrobasilar circulatory disorders, group of disorders, blood supply, the brain is disrupted, vertebrobasilar system, the posterior circulation, the brain, 3 main vessels that provide circulation, the brain, 2 vertebral arteries, 1 basilar artery, the brain contains structures, crucial, sustaining life, instance, brainstem controls respiration, swallowing, level of consciousness, structures, the back, the brain, the occipital lobes, vision areas, the brain, cerebellum, motor coordination, blood flow, in the posterior circulation, the brain disrupted by many different conditions, most common cause is stroke, hardening, the arteries, atherosclerosis, atherosclerosis occurs, fat accummulates, blood vessel wall, causing local inflammation, irritation, swelling, areas of inflammation, plaques, break off, blood clots inside the vessel, clots, travel inside the arteries, get stuck, in the brain, blocking the blood supply, fed by the artery, abrupt stopping of blood supply causes, rapid malfunction, death, the affected brain cells, very sensitive to lack of circulation, what happens, a person suffers a certain type of stroke, vcd, dissection, tear, the artery wall, involves bleeding, the artery wall, the release of a clot which then blocks blood flow, dissection, plaques, the arteries, fibro-muscular dysplasia, by trauma, car accident, manipulations, the neck by a chiropractor, massage, the time, no apparent cause of dissection, less common causes, vertebrobasilar vascular disorders include connective tissue diseases, instance, lupus, forms of arthritis, vasculitis, loss of vision, particularly affecting same part, the visual field on both eyes, double vision, vertigo, sensation of things spinning around, numbness, tingling, nausea, vomiting, difficulty swallowing, balance, poor coordination, headache, neckache, loss of hearing, slurred speech, ordered, what the underlying cause is likely to be, imaging, the brain, ct scans, mri, imaging, the blood vessels, mri angiography, mra, ultrasound, computed tomography angiography, cta, another type of blood vessel imaging, imaging, the heart, echocardiogram, conventional angiogram, x-rays, the arteries using injected dye, lumbar puncture, spinal tap, rarely needed, blood tests, electrocardiogram, ecg, holter monitor, a prolonged ecg to look, abnormal heart rhythms, x-rays, transcranial doppler, ultrasound, the blood vessels, the skull, special coagulation tests, requested, the diagnosis is unclear, patient has an abnormal tendency to form clots, management, divided into emergency treatment, prevention of recurrences, critical to seek medical attention, fast, a stroke, brain attack, type of stroke is one, rapid medical attention, the difference, death, between mild, severe disability, hospital, 3 hours, onset of symptoms, use of a medication, t-pa considered, a clot-buster, given intravenously, injected, veins, has been shown to improve the chances of a meaningful recovery, unfortunately, t-pa, potentially dangerous drug, it, cause bleeding, in the brain, hard to tell whether a stroke has been, a clot, by bleeding, giving this medication, in the case of a stroke, bleeding could be fatal, careful evaluation must be done, physicians must order several tests, careful physical examinations to make sure that t-pa, right treatment, physicians, deliver the clot-buster using a small catheter inserted, the skin, is then advanced, blocked area, the brain circulation, the aid of x-ray angiography, tried, too late, the 3-hour window required, the intravenous t-pa, unclear at this time, better than using other treatments, prevention of new strokes depends on the underlying cause, always critically important that blood pressure, heart conditions, blood sugar, cholesterol problems, all addressed, plaques have caused a stroke, blood thinners that block the function, sticky cells, the blood, platelets, most important of these drugs is aspirin, other drugs of similar effectiveness, clopidogrel, ticlopidine, dipyridamole, one recent european study showed that the combination, of 2 of these anti-platelet drugs, aspirin, dipyridamole, better than either drug alone, prevent, recurring strokes, a dissection is found, left to resolve on its own, aspirin, warfarin, another blood thinner, 3-6 months, significant blockage of a blood vessel, an angioplasty, open up the artery, a balloon, a stent, keep it open, stents, not universally available, contrarily, placement, a stroke, vascular problems exist, a result of another illness, vasculitis, steroids, immune-suppressing drugs used, prognosis depends in part on the underlying cause, strokes, the brainstem region, potentially life-threatening, demand urgent medical care, most important prognostic factors, associated medical problems, patients, young, have no significant medical problems, a substantial recovery, expected, recovery also depends upon the area, the brain, affected, prognosis is very poor, the patient is in coma, cannot move both arms, legs, complications of vertebrobasilar circulatory disorders, stroke, its complications, complications of stroke, respiratory failure, require use of mechanical respiration, lung problems, lung infections, heart attack, dehydration, swallowing problems, the placement of tubes, in the stomach, artificial feeding, movement, sensation, paralysis, numbness, formation of clots, in the legs, patients, have visual loss in one eye, complications, medications, surgery, have any symptoms, suggest a vertebrobasilar circulatory disorder, remember the motto, the stroke neurologist, "time is brain", prevention of strokes, disorders includes cessation of smoking, regular exercise, blood pressure control, healthy diet, diabetes, prevention of dissection includes avoidance of neck manipulation, trauma, neck.
