33 year old female with hypertension and received mra results that show mild to moderate vertebral artery stenosis. What does this mean usually?

33 year old female with hypertension and received mra results that show mild to moderate vertebral artery stenosis. What does this mean usually?

Need to be watched: Means you have early narrowing of blood vessels in your neck. Which can progress and cause further narrowing and increase risk of stroke. No surgery needed now, but you have to be on high doses if statins and an Aspirin a day. Repeat carotid doppler every 2 years. If you have high blood pressure or diabetes , should be well controlled. ...Read more

Vertebral Artery (Definition)

A vertebral artery is a small artery that comes of of the aorta (the biggest vessel in the body that takes oxygenated blood away form the heart to deliver to the rest of the body) to give blood to the vertebrae. There are two arteries , one right and one left until the aorta splits. Since the aorta runs right next to the vertebral column, ...Read more

I am a 33 yr fit female with hypertension, white matter changes on MRI and vertebral artery stenosis found in mra. Could I have a stroke soon?

I am a 33 yr fit female with hypertension, white matter changes on MRI and vertebral artery stenosis found in mra. Could I have a stroke soon?

Perhaps.: You are probably at higher risk than average for having a stroke. I would recommend taking an adult aspirin a day and modify your risk factors (blood pressure control, healthy diet, weight loss, smoking cessation, cholesterol control, etc.). Speak to your physician for more information. ...Read more

Can past vad - vertebral arterty dissection cause stenosis or a bruit in the carotid artery? Or any other stress to local arteries? What is the path?

Can past vad - vertebral arterty dissection cause stenosis or a bruit in the carotid artery? Or any other stress to local arteries? What is the path?

Not usually: A bad trauma can cause dissection of vertebral and carotid arteries at the same time but rare. Carotid bruit can indicate a stenosis which is usually atherosclerosis. Fibromuscular dysplasia can cause narrowing. Fmd is usually in women. Fmd can affect the vertebral arteries and the carotid arteries. Fmd can cause dissection in vertebral and carotid arteries. ...Read more

Why is my right vertebral artery smaller than the left? Could this cause problems?

Why is my right vertebral artery smaller than the left? Could this cause problems?

Normal: This is a very common finding. Vertebral arteries are typical referred to as right or left dominant. This reflects one artery larger than the other. Both of the vertebral arteries join to form a single artery called the basilar artery within the brainstem. Having one artery that is larger than another has little overall impact and is a normal finding on radiology or angiography studies. ...Read more

Vertebral artery compression. Can i have an MRA scan with my head turned right which is what causes my symptoms??

MRI positional : Yes. If the radiologist works with the MRI tech sets up the scan of your neck but many radiologists can look at the standard MRI images and determine the area of question compressing the artery if they know to look for it make sure they have a good history before they read the study ...Read more

Can a pinched vertebral artery in your neck cause a pulsating sensation in or around your head of the other arteries?

Can a pinched vertebral artery in your neck cause a pulsating sensation in or around your head of the other arteries?

Vertebral artery: No. A pinched (stenotic) vertebral artery may not have any symptoms if the opposite vertebral artery is large enough to carry the additional flow. When there is blockage of one vertebral artery and poor collateral flow from other arteries then the pinched vertebral artery can cause imbalance, spinning of the room (vertigo), and light headedness or fainting. ...Read more

Can vertebral artery dissection cause slight bleed out or form hemotoma on exterior rather then within artery wall - if so, what could that cause?

Can vertebral artery dissection cause slight bleed out or form hemotoma on exterior rather then within artery wall - if so, what could that cause?

Yes,not as above : Vertebral artery dissections can cause bleeding usually from the dissection/rupture of a saccular aneurysm. These aneurysms are more common intracranially than in the extracranial location. The aneurysms are typically located at branch points of the major vessel. Treatment of the aneurysm is typically endovascular, with the placement of coils to occlude the aneurysm. ...Read more
