What is the brain AVM?
Arteriovenous malformation (AVM) is a congenital defect of blood vessels that changes the method of blood circulators, albeit a specific area in the brain. The arteries and veins that do not develop correctly are a cluster that prevents blood flow to nearby tissue. The AVM brain is usually formed at the beginning of the fetal development, although doctors are not sure of precise causes. AVM in most cases does not cause any noticeable symptoms, although this could potentially rupture if blood pressure was too high, which can lead to extensive bleeding and related complications. The torn brain of AVM is a medical emergency that requires surgical drainage and repair to avoid life -threatening situation.
The artery usually adds blood from the heart to hundreds of small capillaries in the brain, which in turn nourish brain tissue. The blood used then drains the veins and points back to the heart to be ooxygenated. In the case of the AVM brain, arteries and veins are accumulated together that causes blood to run directly into veins without achieving brain tkana. The AVM brain is usually small enough to keep the blood flow still through the brain correctly.
Scientists were unable to identify clear causes or risk factors for the development of AVM brain. There is no genetic component, because the problem rarely runs in families. Environmental factors such as parent diet, drug use or lifestyle activity were not associated with the condition.
Most small brain AVMs do not cause health problems. However, it is possible for a child or young adults to experience frequent migraines or seizures that are later associated with AVMS. A small number of older people who have non -decreased, undiagnosed malformations are also developing rapidly declining vision, memory and concentration skills. Bleeding is the main problem of brainavm, which can lead to weakening headaches, loss of vision, numbness and problems with speaking and breathing.
brain AVM cane be undiagnosed until it is discovered during tests for other problems such as seizure disorders. If the imaging scan reveals a small AVM, a neurologist may decide to perform preventive surgery. During the surgery, a small piece of skull is removed and AVM is cut by a laser device. Another option that grows in popularity is called endovascular embolization, which includes the delivery of the adhesive type to AVM to seal it and prevent blood flow.
emergency surgery is essential in the treatment of a cracked brain AVM. While the patient is administered by therapy for stabilizing oxygen and the heart supported by life, AVM is quickly removed and excess blood is drained by a vacuum tube. The prognosis after surgery depends on the amount of damage, but many patients are able to perform full recovery with other operations and physical therapy.
