Can a 2mm avm cause small bleeding in the brain?

Can a 2mm avm cause small bleeding in the brain?

AVM: A 2mm avm is an extremely small size avm and impressed they were able to find it on radiologic studies. An avm always has a risk of bleeding but if only 2mm in size this would be a low flow avm and the risks on the lower size. I would recommend followup in the future to make sure there is no growth in the avm as that would change the treatment. ...Read more

AVM inside spine. C4-c5. It has been bleeding. Go in a month to see if stable. How serious is surgery? What's the outcome if left alone?

AVM inside spine. C4-c5. It has been bleeding. Go in a month to see if stable. How serious is surgery? What's the outcome if left alone?

Problem with AVMs: Sometimes an AVM can be serious, especially in this location. Can you say if the AVM is in the spinal cord, or the spine? It may be important. An AVM could be clinically quiet and cause no problems. Larger AVMs (more than 4 cm, about 1.7 inches) tend to be a problem. So size is a factor. An AVM that has bled is at risk for bleeding again. It is the bleeding that often causes a problem. ...Read more

I have an arteriovenous malformation (prefrontal cortex). Now, also really low mean platelet volume. Is the avm's bleeding risk high because of this?

I have an arteriovenous malformation (prefrontal cortex). Now, also really low mean platelet volume.  Is the avm's bleeding risk high because of this?

Platelets: A low mpv in and of itself is not necessarily a risk factor for bleeding if the total platelet count is normal. If treating the avm is not an option, then do avoid Aspirin and ginkgo biloba, which can both increase bleeding tendency. Speak to your doctor about getting an ivy bleeding time test, as it will tell you how well your platelets are working. And do make sure your BP is not elevated. ...Read more

What are symptoms you have with an avm?

What are symptoms you have with an avm?

Depends on location: Avms can present with hemorrhage or seizure. If the avm is located close to the motor region, they can also present with focal weakness because of ischemia from the "steal" phenomenon associated with the avm. ...Read more

What symptoms do you have with an avm?

Depends on location: Avms may present with a bleed, which may be manifest as a headache or alteration in level of consciousness. Patients may also present with a seizure. This is from the ischemia to the surrounding brain as most of the blood to the area is going to the avm rather than the brain. Focal motor deficits may occur if the avm causes adjacent brain (motor area) to suffer from a shunting of blood to the avm. ...Read more

If i had AVM since i was born? would i have symptoms by now? wouldn't it have gotten bigger and cause headaches?

If i had AVM since i was born? would i have symptoms by now? wouldn't it have gotten bigger and cause headaches?

AVM: Most AVM don't expand and are in the proportion in the brain. They don't cause headaches. When they bleed, they may cause seizures or stroke like episodes, best to discuss with your doctor. ...Read more

Can symptoms of meniere disease be a avm?

Yes but not likely: Dizziness, ringing in the ears, and nausea are the the primary symptoms of meniere's disease. This disease is more common than aterio venous malformations. Nevertheless an avm which is located in certain areas of the brain could reproduce some of these symptoms but the common causes are more likely. ...Read more

If i had AVM from being born severely premature, would i have symptoms by now? If i ask my doctor for MRI you think he will order one?

If i had AVM from being born severely premature, would i have symptoms by now? If i ask my doctor for MRI you think he will order one?

Brain AVM: It is unlikely that you have a brain AVM because premature babies often undergo imaging of the brain to ensure there is no brain hemorrhage or hydrocephalus. A brain AVM would have been detected at that time. To reduce your anxiety, I think it is reasonable to obtain an MRI and MRA of the brain now to screen for an AVM or any other vascular pathology. ...Read more
