Cyberknife Treatment for Arteriovenous Malformation
AVM or Arteriovenous Malformation is an abnormal clustering of blood vessels that happens within the vessels that supports the brain and the spinal cord. In a human cardiovascular system structure, blood vessels called arteries carry blood away from the heart, transporting oxygenated blood into various organs, except with pulmonary artery's case. Arteries branch out to smaller ones called capillaries where the actual exchange of nutrients and by products like carbon dioxide occurs. The deoxygenated blood will then be carried through the veins back to the heart for re-nourishment. But in a person with AVM, the blood goes from arteries then, directly to the veins, without passing through the capillaries, making the blood that flows to brain and spinal cord unoxygenated. Case leads to tangling of vessels, usually during the embryonic period affecting fetal brain and/or spinal cord. The condition's major symptom is unpredictable and episodic brain or spinal bleeding or hemorrhage. Manifesting the symptom may result to 10% chance of dying and 20% chance of neurologic abnormalities. Other symptoms include muscle weakness, paralysis, seizures, ataxia or uncoordinated body movements, visual disturbances and the presence of bruit, a distinctive "whooshing" sound brought about by the excessive rushing of blood flow through the arteries and veins of an AVM. Procedures like cerebral angiogram, CT scan and MRI (Magnetic Resonance Imaging) are done to confirm the abnormality. Possible treatments are the surgery, endovascular embolization and stereostatic radiosugery. The surgical removal of the affected vessel or tumor indicates that the patient is cured but it opens the possibility to different complications like infection, cardiovascular disease or stroke and other neurological problems. On the other hand, endovascular embolization is a procedure by which a catheter is inserted into a leg artery, threading to the brain's artery using X-ray imaging and injecting a glue-like substance to block and reduce blood flow into the AVM. Lastly, stereostatic radiosugery uses radiation is used to destroy the AVM. But possibility of occurrence of headaches, seizures and scar formation can also occur after the procedure. Then, another technological treatment is developed. That is the Cyberknife treatment for arteriovenous malformation.
Cyberknife treatment for arteriovenous malformation is a state-of-the-art development using well developed technology, making the procedure more comfortable and more effective. It is a modified streostatic radiosurgery procedure. But compared to the usual stereo radiosurgery, this procedure does not need to put patient in a frame to control his movements. The patient lies on a table comfortably, as the computer-controlled robotic arm moves around him and an X-ray machine directs radiation to the target area in different and various positions and angles. This avoids possible damage to surrounding tissues. No scars are formed. Also, throughout the treatment, there are cameras that provides image guide to accurately locate a tumor. Since non-invasive, the procedure is painless, no scalpel is used and requires minimal or even the absence of sedation. Also, no blood loss complication is manifested in this procedure. The patient can also get back to his/her usual lifestyle after the treatment.
One of the best Cyberknife treatments for arteriovenous Malformation in the world is Colorado Cyberknife. It is also the first Robotic Cyberknife Intensity Modulated Radiation Therapy (IMRT) System, creating a greater hope for cancer patients. It offers individual planning treatment and ensures quality and safe care for every patient. It makes use of comprehensive system that manages every aspect of health care for the patient from pre-planning down to its post-delivery. All of which enabled them to be universally recognized in the field of radiation oncology.

A fast way to get gout relief is with baking soda which I've found it to be very effective. But now that I have gotten my uric acid levels under control I don't need to use this home remedy anymore.
Gout was once the 'disease of kings' due to their diet, but not any more. Anybody can have gout nowadays. Easy access to relatively cheap, mass-produced food and alcohol has meant that we are all at the mercy of gout through our diet.
We need to keep our omega 6 foods at a minimum and include more omega 3 into our diets. Adding food items such as walnuts, chia seeds, to our salads is a simple and natural way to get our omega.
Most children demonstrate some impulsive/hyperactive behavior or have difficulty remaining on-task. Although typically found in boys, in 3-7% percent of children the inattentive, hyperactive, and/or impulsive behavior is recognized by clinician as being a significant problem that is not typical of normal development.

Did you know that you have a brain cell shaped like a star? They are called astrocytes. However, this kind of brain cell may be surrounded by an abnormal mass of tissue called neoplasm. When this happens, the person may have astrocytoma.
Cancer is one of the leading causes of deaths around the world. It claims millions of lives every year, and it is sad to note that millions are presently suffering from it. What is worst is that many people are not aware that they already had it.
Cyberknife treatment for cancerous tumors is one of the latest treatment modalities used by medical practitioners to minimize or to totally eradicate cancer-causing cells in the body. It is widely practiced in Europe and in the United States, and it already revived thousands of cancer patients.
A cancer tumor is more than just an abnormal cell growth. It can be deadly. In fact, millions of people who had it already died, and millions more are presently suffering from severe forms of it.
