Posterior Cerebral Artery Stroke Symptoms
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
In a recent exam my mom discovered that, she don't have the posterior cerebral artery. Is this normal?
There are 2.: Normally there are 2 posterior cerebral arteries. If one or both are missing it is abnormal. ...Read more
What does "minimal ectasia versus tiny aneurysm of the P1 segment of the left posterior cerebral artery" mean??
What does it mean when "minimal ectasia versus tiny aneurysm of the P1 segment of the left posterior cerebral artery? "
Who is the best doctor in the country to treat severe stenosis in the distal p2 segment of the right posterior cerebral artery?
Hard to answer: The first thing to answer is whether you need treatment for it. If so, you are looking at an interventional neuroradiologist who would potentially treat the narrowing with ballon angioplasty. This is not a procedure without risk! ...Read more
Recently, my mother discover that, their posterior cerebral artery was missing or in others words, "don't have any". Is this normal?
Normal no: A "normal" ie frequetly described anatomic variant - yes. ...Read more
Migraine history MRA/MRI results: right A1 anterior cerebral artery is hypoplastic. Right P1 posterior cerebral artery is markedly hypoplastic. Low lying cerebellar tonsils, no chiari. Borderline high riding left jugular bulb. What's the significance?
What does left anterior cerebral artery (a1)hypoplasia on head mra report means? For above is there high risk for ischemic or hemorrhaging stroke (s)?
Normal: It is a common normal variant that doesn't carry risk of stroke. We all have some asymmetry in blood vessels and hypoplasia simply means that blood vessel is smaller than it's counterpart on the other side. ...Read more
Stroke team at hospital evaluated. All tests were negative. Classic stroke symptoms. Current neuro "fishing" with EMG for arm. My concern is brain da?
Unlikely damage: Hard to say what occurred based upon your description, but unlikely permanent brain issues if your studies were negative. Cannot advise re EMG, as do not have full details. One alternative thought might involve an atypical migraine event, and this could be explored. You seem unsure about your doctors, might a second opinion or a Concierge visit here help? ...Read more
Had a lot of head CTs (7-8) & CTAs (2) due to TIA / stroke symptoms over the years and injuries associated to illness. Scared of brain cancer.
Induced Ca unlikely:
I worry more about history of "TIA/stroke" and "injury" in a 38 yo.
Radiation risk for the listed studies is well under 1 in 500 or so and "brain cancer" is even less likely.
MRI is a great test for the brain and vessels as there is no ionizing radiation, BUT you must be able to have the test. For example no metal shavings in your eye from an injury and no unstable implanted ferrous metal. ...Read more
If stroke like symptoms were caused by cervical artery dissection, would this show up in MRV and MRI of brain. Or only a scan of neck?
Depends on timing: A CT or MRI can detect changes of edema (fluid) due to cell death within the brain. Often by the time these changes are seen, it is late in the process. Also this would tell us the arterial territory involved, but not that it is a result of dissection. Emboli or thrombus of an artery are more common causes of stroke. A carotid dissection is less common, though more common in vertebral artery. ...Read more
MRA report. Nonvisualization right A1 &P1 segment. Rt anterior cerebral artery. Congenital or acquired occlusion. What does this mean?
MRA report: The correct thing to do is to ask the physician who ordered the test to explain the findings to you ...Read more
Hmmmm...: The propensity to have a stroke can be genetic. The specific arterial occlusion, not necessarily. But, high colesterol, high blood pressure and family history of stroke put you in a higher risk catagory. If you smoke you increase your risk exponentially. Lifestyle modification can be key. If on the otherhand you are talking about aneurysms--that could very well be linked. ...Read more
Please explain where the left 8th nerve and the a1 segment of anterior cerebral artery are in relation to each other? Both of mine are "hypo plastic"
Far away: They are not near each other. Hypoplastic blood vessels in the brain are occasionally seen on mra/cta studies. ...Read more
" hypoplasia of the left anterior cerebral artery a1 segment is noted. Impression: normal mra of the circle of willis." what does above hypoplasia mea
Unusually small: That finding means that one of the arterial branches in your brain didn't develop fully. Not to worry though because if the report is'normal' that brain territory is getting blood from elsewhere. Many people have hypoplasia of a segmental artery which is usually inconsequential. ...Read more
I had TIAs 5 days ago. The CT scan showed that I had complete occlusion of the origin of the anterior cerebral artery. What are my options?
Prevention: 1. Have your doctor check for numerous risk factors such as hypertension, hyperlipemia, diabetes, inflammation or arteries, hyperhomocysteinemia, cardiac disease, carotid stenosis, chance of emboli from distant source. In general if no emboli would use combination of Aggrenox and a statin for prevention. ...Read more
I dissected an artery 9 weeks ago which caused a cerebular and brain ste, m stroke. My balance is now ok but I am dizzy when walking is this normal?
Will improve: Given time and rehab you will improve you can also talk to your neurologist for assistance and help ...Read more
Vas surg said blocked subclavian L artery. No bp, & barely a pulse. 1 of 4 arteries to brain has reversed flow to try to get blood to L arm? Stroke?
Complicated scenario: Subclavian stenosis & coarctation of the aorta can cause this scenario. You may've been born with a condition & it just progressed. In any case, the situation's VERY complex. There's not enough space here to establish your history, go over ALL of your questions/concerns, & figure out a treatment plan that will reduce complications in the future. You're best off using HealthTap Prime. Good Luck! ...Read more
Diplopia, squeezing band of pressure in head, absent L posterior inferior cerebral artery. Chol/hdl calc 6.7. FH mutation. Could this cause stroke/tia?
No: Minor anatomic variants of the arteries in the back part of the brain are no big deal. Sorry for misunderstanding -- I'm glad your FH / familial hypercholesterolemia was detected & can be managed. Without other findings, band and diplopia are unlikely to be serious ischemic disease, but are classic "functional". You're right to be concerned as such headaches, even if not "stroke", can disable. ...Read more
Does hypoplasia of the left anterior cerebral artery a1 segment increase risk for aneurysm or ischemic and hemorrhaging strokes? If yes why?
It shouldn't: Hypoplasia is commonly a normal finding. It should not increase risk of any kind of stroke. ...Read more
Since coiling of brain aneurysm on right carotid artery, I had 3 tia's weeks after surgery. 6 months has past, but I'm scared of having a major stroke?
Yes. Call Now!: Patients who have had carotid artery surgery definitely have a risk of stroke. The highest risk of stroke is during and immediately after the procedure and is generally quoted at about 2%. If you are experiencing any signs of stroke and have had recent carotid surgery call your surgeon immediately or go to the emergency room. Difficulty speaking or weakness on one side of the body would be the most common complaints. ...Read more
Yes: But am not really impressed with aspirin potency in preventing a stroke, as clopidigrel and Aggrenox seem more effective. ...Read more
This could be stroke: Or it could be from other causes of left arm numbness. Is there weakness? Is there increased reflexes. If you think you have a stroke you should see a doctor as soon as possible. An MRI done with diffusion weighted imaging can tell if you have a stroke. Ask your doctor fi this could help you. ...Read more
See below: If there is no significant facial droop, I would try swallowing an Aspirin with the smallest amount of liquid needed. If you are having trouble swallowing the tablet, place it under your tongue. Aspirin is quite bitter! Many stroke victims, especially those with facial droop have difficulty swallowing. In our ed we give our patient's a rectal suppository of aspirin, I wouldn't expect you to have it. ...Read more
I'm 16 and afraid of having a stroke. Also have anxiety which mimics stroke symptoms. I have normal BP and cholesteral?
Get seen: Their is help for the kind of anxiety you are feeling. Let your parent or guardian know. Get a full physical work up and ask for a referral to see a therapist. There is no shame whatsoever in asking for psychological help at your age. It can make all the difference for a healthy productive life. Good luck and best wishes. ...Read more
