How do arteriovenous malformations damage the brain and spinal cord?

Hemorrhage: Most of the damage of an arteriovenous malformation occurs when the blood vessel or vessels are spontaneously ruptured and bleed into the brain, causing pressure and damage to the brain. The same can occur with an av malformation in the brain stem or spine. ...Read more

What are neural tube defects?

What are neural tube defects?

NTD: Neural tube defects are a host of lesions that affect the spinal cord. They vary in degree from spina bifida occulta ( mildest ) to craniorrachischis totalis ( severest), spina bifida, and myelomengocele being the most frequently encountered. They have been linked to a diet deficient in folate (folic acid) during pregnancy. ...Read more

Is arnold chiari malformation type one a neural tube defect?

Is arnold chiari malformation type one a neural tube defect?

No: The more accepted term is chiari malformation as arnold-chiari is an older term. This type of malformation is not a neural tube defect, but rather an abnormal migration of the cerebellar tonsils below the level of the foramen magnum (chiari type 1). This defect is attributed to a congenitally small posterior fossa, thus allowing the cerebellar tonsils to migrate downward. ...Read more

What nutrient prevents defects of the baby's spine and brain?

What nutrient prevents defects of the baby's spine and brain?

Folic acid: It has been shown that folic acid is critical to the development of the spinal column in a baby, and using a supplement with folic acid dramatically reduces the incidence if babies born with myelomengicele. ...Read more

Could the oxygenation of my brain affected before asd(atrial septal defect)closure?

Could the oxygenation of my brain affected before asd(atrial septal defect)closure?

Not usually: An ASD does not generally affect oxygen delivery to the brain (or the rest of the body). The only exception would be in the setting of severe pulmonary artery hypertension in which low oxygenated blood can flow from the right atrium into the left atrium and be pumped to the body. ...Read more

Are neural tube defect babies active?

Are neural tube defect babies active?

Possibly: It depends on multiple factors. There are different degrees of neural tube defects. Some people can have a mild defect and other may have a severe defect.

Are subarachniod cysts in the temporal lobe area related to chiari malformations?

Are subarachniod cysts in the temporal lobe area related to chiari malformations?

No: Subarachnoid cysts are common and are usually asymptomatic. The middle cranial fossa where the temporal lobe sits is a common location for these cysts. Arnold-Chiari malformations involve the posterior cranial fossa, not the middle fossa unless there is secondary hydrocephalus. http://radiopaedia.org/articles/arachnoid-cyst ...Read more

What is neural tube defects often mentioned in pregnancy..?

Spina Bifida: "neural tube defects" is a general name for developmental problems regarding the early developing spinal cord. The most commonly known defect is called "spina bifida" -- a defect in which the developing spinal cord is open to the skin on the back of the baby. This can lead to bowel or bladder control problems, neurologic problems, and even paralysis. ...Read more

Afp normal, enlarged brain ventricles, is it still possible to have a neural tube defect ntd?

AFP: A normal AFP reduces the risk of an open neural tube abnormality. Enlarged cerebral ventricles are usually not associated with neural tube abnormalities. ...Read more

Can baby with anencephaly grow a brain with stem cells?

Can baby with anencephaly grow a brain with stem cells?

No: Brain growth in utero concides with growth of the body and skull and the brain has already spent 9 months growing and responding to stimuli in the womb. A full brain would not grow correclty from stem cells after birth. ...Read more

Is the treatment for arteriovenous malformations (avm) ofthe brain through arteries now?

Not "ALL": The treatment of avms is should involve mutliple specialists these days. Some of the more recent research suggests that treatment through the arteries is dangerous but it is important to realize that many of those treatments did not involve a team of doctors treating the patients.

Having mri/mra of neck, carotid, and posterior fossa - will it show masses in the cerebellopontine angle, jugular, vagal, vestibular schwanommas, etc?

Having mri/mra of neck, carotid, and posterior fossa - will it show masses in the cerebellopontine angle, jugular, vagal, vestibular schwanommas, etc?

Head and Neck Masses: Mri uses large magnets to create images of possible masses. Mri is a related technology that images blood vessels to look for blockages or aneurysms (ballooning). While there are some more specialized tests to look at certain areas, in general, the answer to your question is yes. ...Read more
