Ectasia Of The Basilar Artery
What is tortuosity of the basilar artery and the basilar artery impresses upon the lower brain stem.?
A radiologic descrip: I'll presume you're reading off a radiologic report that involves imaging the arteries within the brain. Description that an artery is 'tortuous' means its curvier than usual, and not abnormal; basilar artery sends blood to brain stem, located in basal part of skull in back of your head; whether any clinical significance to 'impresses on the brain stem' needs to be interpreted by neurologist. ...Read more
Arteries are defined as blood vessels which carry blood away from the heart (to either the body or lungs). Arteries: higher pressure, thicker walls, stretch (pulse) with each heart contraction & deliver blood to the arterioles which control the flow to individual capillaries. Veins are blood vessels which carry blood from capillaries back to the heart (body to right heart; ...Read more
MRI vertebrobasilar hypoplasia right side theres robust flow void anastomosing the basilar artery w cavernous portion of internal carotid artery/mean?
Normal variant: The arteries at the base of the brain can course in several different patterns but ultimately get the job done, that is, supply brain tissue. Your pattern is like your fingerprint. Some more unusual patterns have an increased association with aneurysms, but this would have likely been described if present and vertebro basilar hypoplasia, as in the picture, is pretty common. ...Read more
What does "minimal ectasia
versus tiny aneurysm of the P1 segment of the left posterior cerebral artery" mean??
Arterial tear: An uncommon cause of stroke, but among younger patients, it is one of the most common. Sometimes spontaneously, sometimes after an activity that involves sudden torsion to the neck, a tear may form along the three layers that constitute the arterial wall. This tear causes turbulent blood flow and predisposes to clot formation. These clots can then cause a stroke by blocking important arteries. ...Read moreSee 1 more doctor answer
Ischemic stroke: Carotid artery disease usually occurs at the origin of the internal carotid artery at the neck and results from plaque build up. The main concern is that blood clots may for from turbulent blood flow this plaque causes, and the clot may travel upward and block an important brain artery, causing a stroke. It is a common found and commonly treated cause for stroke. Several options exist. ...Read moreSee 1 more doctor answer
Arterioclerosis: Arteriosclerosis or plaque buildup in the wall of the coronary arteries will narrow the lumen to the point where there is flow restriction, then clot formation. The plaque may rupture, allowing a flap-like effect, blocking the lumen, resulting in clot formation. Trauma may cause a separation of the layers of the wall, and this dissection results in clot formation. ...Read moreSee 1 more doctor answer
Variable significanc: It depends on how large the fistulas are. A small coronary fistula can be without major effect. However, I have seen large coronary fistulas that require surgical or catheter repair. I suppose "bilateral" means both left and right coronary arteries have connections to either a coronary vein / atrium or other venous structure. ...Read more
Arteriosclerotic internal carotid & vertebro basilar arteries predominantly the left vertebrobasilar segment appearing tortuous with slight prominence?
Picture this: The coronary arteries branch off from the walls of the aorta, and dive down into the outer layer of the heart mucle. On the left side, the left main artery branches into the left anterior decending (lad), which runs down the front wall of the heart, and the circumflex, which runs around the lateral wall. On the right, the right coronary artery runs along the bottom wall of the heart. ...Read moreSee 1 more doctor answer
Several: There are a number of risk factors that lead to plaque in the coronary arteries which is the reason for the blockage. Some of these are smoking, high blood pressure, unhealthy diet, an abnormally high cholesterol, lack of exercise, and obesity. There are also hereditary factors. ...Read moreSee 2 more doctor answers

Chest pain: There may be no symptoms but if the blockage is severe enough, chest pain, especially on exertion, can occur. Also heart attack or even sudden death. Therefore, good to see your doctor and be advised of your risk factors and ways to prevent coronary artery blockage. ...Read moreSee 1 more doctor answer
I have been told I have mild ectasia of the basilar artery. I suffer with migraine and my father has multi infarct dementia. Should i be concerned?
Outdated concept: There's no such thing as basilar "artery" migraines. The term basilar migraine dates back to a time when migraine pathophysiology was thought to involve arterial wall constriction followed by compensatory dilation. Basilar migraine was thought due to basilar artery spasm. This notion has been discredited; however, the term is firmly entrenched & we all use it & know what it means & doesn't mean. ...Read moreSee 2 more doctor answers
Yes: It can happen.Get a more detailed answer ›
Just is: The carotid arteries are anterior circulation vessels; you can think of them as supplying the front of the brain. The basilar artery is at the base of the brain and is created by the confluence of the two vertebral arteries, which are posterior circulation vessels. It is possible to have disease in only one of these vessels, or in all of them, or in any combination. ...Read moreSee 2 more doctor answers
Basilar for brainstm: The top of the basilar artery is like a fork in the road. When a blood clot affects this area, small strokes can occur in the brainstem, causing numbness, weakness, trouble talking, eye symptoms, or impaired consciousness, and sometimes, more than one stroke occurs at the same time. ...Read more
Medullary compressio: This is not an uncommon finding in people over 65 on mri scan. It is significant if you are having symptoms such as dizziness, black out spells or blood pressure fluctuations. It can frequently such be followed by a neurologic professional, but should generally be evaluated by someone with experience in cerebrovascular disease. ...Read more
Meds, reduce risks: This is generally from narrowing/blockage of the arteries to the back of the brain. Symptoms of this can vary, but often include dizziness, difficulty using an arm, loss of sensation of face/arm/leg. It is treated with antiplatelet medications (eg. Aspirin, plavix, (clopidogrel) aggrenox), controlling cholesterol, blood pressure, diabetes, cessation of tobacco use, and in some cases placing a stent. ...Read moreSee 1 more doctor answer
Brainstem origin: More common in woman, is associated with an aura of < than one hour followed by a headache. The aura produces a field cut (loss of vision) leading to temporary blindness, followed by ataxia, vertigo, tinnitus, nausea, vomiting, slurred speech, bilateral paresthesia, or a change in the level of consciousness. It affects all age groups and both sexes. The presentation can be confusing. ...Read moreSee 1 more doctor answer
Varied: In about 25% of patients, vertigo, slurred speech, and diplopia imply altered brainstem function. Commonly in adolescent women but also in others, total blindness and sensorial clouding accompanied by vertigo, slurred speech, tinnitus and distal/perioral paresthesias followed by a confusional state. The symptoms usually persist for 30 m followed by a throbbing occipital headache. ...Read moreSee 1 more doctor answer
Extensive: Manifestations include dizziness, vertigo, ataxia, visual disturbances such as double vision or tunnel vision, numbness and/or weakness in face/arms/legs, clumsy speech. This is often familial. A higher stroke risk exists with this type. Blood clotting abnormalities may be present predisposing to strokes. ...Read more
